Playing with a pump gun can be fun and challenging. If you want to see my opinion on taking the pump gun challenge, read the “Why Play Pump?” page. If you’ve already decided on playing pump, stay right here and maybe I can offer some tips. Overall tactics for successful pump gun play are not that different from using a semi-auto. Actually, a lot of what’s on this page will work for players regardless of their gun. The main difference is the pump player doesn’t have as much fire power to rely on, so he can’t afford to be sloppy. While tactics in general play differ.
Things to avoid
With a pump gun you are at a definite equipment disadvantage – not simply because of a lower rate of fire, but also because you have to use two hands. Therefore, you should avoid certain situations.
One of the first things to remember is not to get yourself in a situation where you won’t be able to use both hands when you need them.
Considering the rate of fire differential, you should also avoid going head to head with a semi-auto. Regardless of the type of equipment you are using, taking your opponent head-on is hardly ever the best tactic. Even if the two of you are on equal footing, you only have a 50% chance of success when you go head to head. If he has a semi and you have a pump, the odds just went up in his favor.
This is one place the pump player cannot afford to drop the ball (pun intended). Without the ease of quick “water hose” follow-up shots to guide you, as a pump player, marksmanship is your best friend. When playing pump, it is very important to be able to put your first few shots on target. Familiarity with your gun, along with a good, quick, sighting system can bring deadly accuracy (and lower paint bills). Although paintball guns may not have pinpoint accuracy, most are certainly accurate enough to take advantage of simple sighting systems. Whether you are using open post sights on the gun, or an electronic red dot system, the key is to learn how your gun shoots in relationship to the aiming point of your sight. If your gun shoots a 6 inch wide pattern at 30 yards, then attempt to zero the sight in the center of the pattern. At least that way, you’ll know the ball will hit within 3 inches of where you are aiming.
Learning how the gun shoots can only come from repeated use of the gun and sighting system as a unit. Gaining an intimate familiarity with how your gun shoots is the single most important skill necessary in pump play. Knowing that with only a few shots you can quickly hit whatever you want is confidence inspiring to such an extent that a lot of players refuse to play anything but pump (ironically, the same concept is achievable with semi-autos, but I suppose there’s less incentive to put that much effort into it).
Like anything else, practice and experience will bring confidence when playing pump. Confidence also grows from being successful, and success comes in part from your state of mind. You have to believe that you can win, despite having an equipment disadvantage – and the fact is, you can. You have to believe that you make things happen – not your opponent, not the field lay out, and certainly not the gun.
If you head out on the field with an attitude of the situation being hopeless because you are outgunned, that’s exactly what it will end up being. What will naturally follow your defeat is using the gun for an excuse. After all, it’s much easier to blame the gun than to admit you could have done better, right? That is an attitude pump players can’t afford to have. Take responsibility for what you did or didn’t do. Instead of telling yourself, “if I’d only been able to fire faster, I could have hit him,” tell yourself “Next time I’ll move to a better position where I will hit him.” Realize that overcoming the inherent disadvantage of playing with a pump is largely a matter of playing smarter, and avoiding the kind of sloppiness from which heavy firepower can save your butt.
Despite what I believe to be my unnatural tendency to get older and slower as my opponents become, equally unnaturally, younger and faster, I still have a good time playing pump. Part of that is because I actually play better. I think when I play with a semi-auto, I tend to have a lazy, laid back attitude (which is something I should be able to overcome now that I am aware of it-ha). The way I play pump tends to be more aggressive, meaner. I do very little hiding and lots of forward movement. If I can’t hit my target, I move as quickly as possible to a position where I can. I try not to stay in one position too long and give people with semi-autos a chance to pin me down in a hail of paint. I also try to realize when I am in a situation where withdrawal is the best option. My attitude when playing pump really comes down to a single word – determination. A determination that comes from the fact that I know I am at an equipment disadvantage, but if I work hard enough, I can win. It’s a very satisfying concept when it comes to fruition.
When looking at an object or area at night make a figure eight by moving your eyes in that direction. Your peripheral picks up more than your retinas at night. By moving your eyes in a figure eight you scan the target so fast that you mind can remember it all and you can somewhat decide if you saw something or not. Its better than just looking straight at the object or area.
When patrolling at night you must keep an interval distance of no more than 8-9 meters. On a moonless night no more than 5-6.This keeps the squad separated enough so that if an ambush, mine, or grenade was thrown then they would not all be killed at once. You don’t want to be so wide apart that if contact is made you turn and hit your man just because you saw movement and you thought he was somewhere else.”Cat’s eyes”work very well. They are reflective glow strips that go on the back of a soldiers kevlar or cap. You can see these strips for quite a distance depending on light source. You can pic them up at any military surplus store. Kem-Lights are also good for night operations but give off a lot of light. They now make tiny kem-lights to replace the cat’s eye’s. The kem-lights go out and the cat’s eye’s can be sewn or glued to objects so your best bet is to go with the cat’s eye’s
At night sound travels farther and louder. Most think its due to the fact that traffic is non-existent, people are asleep, and animals are asleep for the most part. If patrolling at night hand signals and good training is a must to be affective. Simple hand signs go a long way for you in terms of stealth and coordination. Some military missions are conducted with out ANY voice commands at all. In this day and age the elite are using throat mics. These are awesome! The good ones only transmit your voice and nothing else.
If patrolling and you think you are spotted or you hear a noise “STOP”. Don’t move. Most people are seen because they are moving. Your body gives of a larger and darker form at night when you are silhouetted against thin branches and shrubs. If you know you have been seen, and contact is imminent you must act first. This is where good team coordination comes in. Your team must have trained prior for just this problem. You only have 3 choices:
If you decide to attack then a charge is your best bet. I know it sounds stupid but a moving target is harder to hit than a stationary target. The enemy wont expect it, and you can out run a set explosive that was pointing in the target area you were just in.Not to mention that you are probably standing right where someone has been watching and waiting just for you.If you do decide to John Wayne it then watch your lanes of fire and check your targets. Your partners could have advanced ahead of you so dont throw ordinance. You could hit them by mistake. If anyone does throw ordinance it will be the team leader more than likely.
If you decide to run then your best chance of regrouping is having a set “Rally Point”. Start doing an assessment of men and equipment. When on a patrol the pointman or the team leader will assign a rally point every mile or so. This would be different for paintball players since the battlefield is smaller. But it helps to have a pre-designated point to regroup too if you are ambushed and even if you are running a raid or getting into a hasty ambush(get into that later).
Surrendering is not an option but since I gave tips on the other I will give this advice for those that surrender. In paintball surrendering is a mental letdown for anyone who has to do it. In the real world it’s a long mental and physical road for ANYONE.I was taught that if caught be respectful as long as you have to. Be the GREY man. That means don’t stand out. DON’T volunteer info or volunteer to work all the time. DO what everyone else does. Basically make it so that you DON’T stand out in front of your captors. Remember everything that’s going on around you as much as possible. It will help if you decide to escape. There’s A LOT more to this but Im not going to go into it.
For those that smoke. A person smoking a cigarette at night gives off a 5 foot radius(at least) of light when you are looking at them through night vision. In the army we would watch groups of men huddled around each other smoking and read their rank, name, badges and unit patches. To help give you a picture of just how much you can see using NV’s; you can see their eyes as if you were seeing them in the daylight. I quit smoking while in the army just because of that fact.
Light discipline is a must to be stealthy. Using a red lens in a flashlight cuts down dramatically in giving off light plus it doesn’t kill your night vision. It takes your eyes 20-30 minutes to fully adjust to seeing in the dark. When in a conflict at night it’s a good tip to keep one eye closed .If an explosion goes off and you have both eyes open then you have lost your vision. But if you had one closed and you open it you have a better chance of seeing. NOW….that doesn’t mean you will be able to see very well but it’s better than nothing. On a side note flash bangs that are used have enough candle power to blind you even with your eyes closed so don’t think you will hold the cops off just cause you closed you eyes.
Moving at night is tricky. When moving use shadows and depressions to your advantage. When patrolling at night you must stop and listen every few minutes or so. This helps you know if any sounds are different than the normal. This also helps in catching someone off guard if they have been following you. When moving do NOT go over the tops of hills ridges and walls. Your silhouette will give you away. If you must cross over a wall at night stay flat with the wall and hug the object. Do NOT cross over the tops of hills and ridges. Take that extra time to go around.
Im not going to go into night land nav just because I would need pictures and diagrams and not going to go into all that. My biggest tip for traveling in the dark is simply don’t do it if you don’t have to. Its very easy to get lost; even in your own backyard woods. DON’T use a constellation as a guide. They actually do move. I know your saying “I knew that already” but sadly I’ve heard it told by a grown man. The north star is your best tool for a guide if you don’t have a compass. If you are lost and need a way out then your best bet is to find a river or a stream and follow it till you hit civilization.
A trap in which concealed persons lie in wait to attack by surprise on a moving or temporarily halted target. It enables a small unit to set up and destroy a larger and better armed unit.
There are 2 types of ambushes:
1. Hasty ambush
2. Deliberate ambush
The hasty ambush is set when imminent contact will be made. This is primarily used when you know the enemy is after you or you have seen them approaching before they saw you and you have enough time to set one up. If you don’t have time you must make a decision on whether to stay or run. If you stay you must have the advantage position wise and weapon wise. Otherwise run and find a position you can defend.
The deliberate ambush is a planned action against a target. This is primarily used on well travel routes or areas in which you have intel or have watched the target for days (months even)and have a good idea of the area. To have a successful ambush you must have good concealment. Pre-planned firing lanes are a must. This is where anti personnel ordinance is at its best. A well placed claymore can eliminate an entire platoon.
Your men must wait until the person assigned to start the ambush fires his weapon or sets off any ordinance. Hit your target and then go to your next pre-assigned target. Once the ambush has gone off (successfully I hope) you will send your security teams to close off lanes of travel, another security team will check weapons, documents, and search for POW’s. In some paintball scenario’s eliminating a certain person requires that person to hand over an object or info. Its always good to have a security element that isn’t part of the ambush line. These guys watch the ambush’s teams backs. They can also come forward to help with firepower if the ambush has gone wrong. IF the ambush has gone wrong once again go to your pre-determined rally point.
There are 2 main types of ambush formations….the Line formation and the L formation. The line formation is good for assaults after the ambush has been started. The L formation is good for having interlocking fire in which the enemy is hit by 2 different directions. Fire discipline is a must for the L formation.
The best formation in setting a good ambush is what’s best for your team and the terrain and situation. Concealment, firepower and fire discipline are the keys to eliminating your enemy before they even know what happened.
The most important rule in an ambush is this; The moment the ambush is set it is a natural thing for an untrained soldier to completely unload every round all at once into the kill zone. This is a big mistake that can cost you and your team. Let the heavy gunner do his thing, let the m-203 do its thing and just hit your target and stay in your lanes of fire.
Reconnaissance; A preliminary survey to gain information. Recon is what makes or breaks a military. Without info you’re blind. In today’s world we now have drones, planes and leg units watching targets all over the world gathering information and reporting it back to command.
When gathering intel on a unit the best way to get every bit of important info is to do what I was taught.
Its called a SALUTE report:
Size – How many do you see.
Activity – What are they doing?
Location – Where on the map are they?
Unit – Who are they? What team?
Time – When did you see this?
Equipment – What types of weapons are they carrying?
If you use that simple plan when gathering info to give to your commander then you will have every bit of info they need to make decisions. On a side note one thing they left out was which direction did they come from and where do you think they are heading? That is key when deciding to send troops and also pull the recon team out of the area.
When on a patrol and you come up and encampment or the target area they following steps are what usually happen.
When setting up the defensive position for this mission it is best to do a circle formation. This gives a 360 view. Also teams make a safety word for coming back after the recon. You don’t want to shoot your own man after doing his job now do you? It’s really called a challenge and password command. It can be set so the security team[‘s word is house and the recons team’s word is apple. If the recon team gives the wrong word then they get it. That is drilled into your head if you go into the military.
Elite units have been know to laager up and watch a section of area for months at a time. If you must set up a bivouac(temporary encampment under little or no shelter) then here are some tips to keep you from being seen.
BOUNDING OVER WATCH
This is a type of tactic used to move onto a target while being covered by others while you are in the movement phase. Some call it leap frogging.
While moving from your concealed position here are a few tips.
NOW you can use this technique for moving men and even squads onto a target.
Once again it is important to know your fields of fire so that all angles and areas are covered.
Most units will use a staggered man form of fire. That is where one man looks left while the other looks right some look forward and others check their rear. That is just an example.
MOVEMENT UNDER FIRE
Do not move on an empty clip(loader).you may have to engage a target that you know sees you and will fire before you can reach safe cover. The best thing to learn is counting your shots. It saves time.
Do not run in front of the covering man line of fire unless you have to. If you do run low and as fast as u can so you do not block his sight.
Tape all loose gear to your equipment(non reflective tape).It keeps the noise down and you don’t want to loose your NVG’s or all your paint running out in the open.
Stay low and zig zag a bit while in motion. Don’t make it easy for them. Its extremely hard to hit a moving target. Especially with your adrenalin pumping, smoke, noise and what ever else is going on at the time.
If you have smoke use it if the wind is right. They cant hit what they cant see. A highly trained soldier will not fire until he has an absolute shot. the smoke will conceal movement and also set a fire at the same time if you want to start burning a gap between the 2 contacting forces.
Keep you head while under fire. Pay attention to your route. Its funny to see someone running full blast to a position only to lay themselves out due to a branch or board that was overhead. But when its you it’s a different story. So keep your head up and stay alert.

The troubled gun
The Line SI Promaster was one of the early open bolt blow-back semi-auto paintball guns, having made it’s appearance on the market shortly after the Tippmann 68-Special and PMI-III (later VM-68). The initial production gun suffered from several design flaws which quickly created a bad reputation and eventually lead to the gun’s demise. That was a real shame, because when they worked, the Promaster would shoot better than any other stock gun I have ever owned. For accuracy and consistency, no off-the-shelf blow-back being produced today even comes close. My Promasters always produced extremely consistent velocities, and Line SI always made very good barrels.
In 1991 I bought one of the early Promasters because it was the first gas operated semi-auto paint gun the company that manufactured my Bushmaster pump. (Line SI had also manufactured a double-action trigger-cocking semi-auto called the Advantage. I owned one of those for a while. It had a long, hard trigger pull.) The Promaster would use Bushmaster barrels, of which I had several. The original cost was around $400.00, and at least 4 different friends of mine also bought the gun. With Line SI’s reputation, We couldn’t wait to get our hands on the Promaster.
Most people who now see the Promaster assume incorrectly that it is just another in a long line of Spyder clones. The Promaster, while having almost identical operation and similar dimensions internally, preceded the Spyder by several years. From what I can remember, the Promaster also preceded the F-1 Illustrator, which most people give credit for the development of the Spyder . Although the Spyder design and operation is the same as an F1 Illustrator, the Spyder should probably be considered a Promaster copy. The internal valve, valve pin, main spring, bolt, and hammer on the Spyder are very close to that of the Promaster. As a mater of fact, a lot of those parts will actually function inside of a Promaster with no modification. This is not the case for the F-1. The initial production Spyders even had the same color scheme as the late model Promasters. The first time I saw a Spyder, from a distance I thought it was a Promaster.
Promasters had several nice features. The barrel was removed with a simple thumb screw, exactly like the Bushmaster. The snub can be removed from the body with a thumb screw, giving easy access to the bolt, and feed chamber for cleaning. The grip frame is hinged for easy access to the trigger/sear area, although getting into this area of the gun for anything other than trigger modifications is never necessary. The trigger shoe is held on by a single screw and is the same piece that appears on later Indian Creek Designs guns.
Being one of the early blow-back semi-autos, it’s easy to see how the problems in the Promaster design were unforeseen. One of these was the connection between the rear most part of the two-tube design. While the slot for the link pin between the bolt and hammer is milled completely out on modern two-tube blow-back guns, on the Promaster it was not. There was a slot machined for the link pin, but it did not extend all of the way to the back of the gun. This caused the link pin to eventually break, as it slammed back time after time against the connecting aluminum material. The solution was to remove this material, which Line SI eventually began doing on their production guns. I did mine with a hacksaw. This modification also made pulling the bolt/hammer combo out of the gun much easier, where before the link pin first had to be removed through a hole in the top of the gun (like the F1 Illustrator).
Another immediate problem with the gun involved the double feeding of paintballs. This was caused by the poor design of the ball detent, which was a spring-loaded metal ball in the bottom of the snub. Getting two balls per trigger pull was a fairly common occurrence, especially when using smaller balls. Naturally this led to a high occurrence of ball breakage. Later model snubs addressed the problem by placing a spring loaded lever on the side of the snub. The thumb screws seen in the pictures are used to hold the Bushmaster barrels in place. These often vibrate loose unless you really tightened them down hard – which of course means you have a hard time getting them loose. Many people replaced the thumb screws with set screws for more reliability.
The early Promasters, although flawed in design, were well built. However, within several years of production, something went awry with some guns. My friends and I heard rumors (Even from Ross Alexander with Line SI) that there were other companies producing knock-offs, or somebody was producing shoddy licensed copies, and so on. This further added to the bad reputation of the gun. After owning three different Promasters, many parts have made their way into my collection that were somewhat odd. For instance, I have six different snubs, and no two are exactly alike. Some have a dip in the breech where the ball drops while others are smoothbore.. some have rounded edges on the ball detent holder, while some are squared off .. and they each seem to have slightly different internal dimensions. I have also seen this type of inconsistency with hammers, bolts, and other parts. One of the things I had to do to get the gun operating smoothly was hone out the inside of the snub. Some of my unhoned snubs will not even allow the bolt inside, while some will kink the bolt in a bind when the snub screw is tightened.
Blow-back from Blow-back
Like many guns of it’s type, the Promaster also suffered from excessive gas in the ball feed tube, or “blow-back”, as it’s commonly called. The problem can lead to a ball chop by interfering with the ability of balls to drop into the breech in cycle with the gun under rapid firing. This especially happens when the loader jams or run out of balls and there are few balls in the feed tube and the elbow.
Some guns address this problem by mounting a “power feed”, which first appeared on the blow-forward AGD Automags, and are now standard equipment on most blow-back semi-autos. Other guns tried to address the issue by adding O-rings to the bolt. On my Promaster, I have made a multi-prong attack on the problem over the years. The first thing I did was to drill holes in the feed tube and elbow in order to relieve some of the blow-back pressure. This seemed to help a little but did not completely solve the problem. Then I made an attempt to use a small knife and carve a slot in the plastic part of the bolt for an O-ring. My first attempt failed horribly, resulting in a broken bolt. The second attempt was made on a bolt which was made from a different kind of plastic, and survives to this day, many years and cases of paintballs later. However, this had only a minimal effect of eliminating blowback.
One solution that worked very well to address the problem was to add a VL2000 agitator loader to the gun. This assured no more jamming in the loader, which meant the feed tube and elbow were always full of paint until the loader ran out. This addition alone allowed the Promaster to achieve a relatively high rate of fire without chopping balls.
Another solution to the problem is a simple one I should have realized sooner: keep liquid Co2 out of the gun! Liquid Co2 expands so much when the gun is fired that it produces a lot of excess gas (and noise). Eliminating the liquid, by whatever method, greatly reduces the “blow-back” effect. Along these same lines, lowering the operating pressure is another way to combat the problem – more on that later. As a side note, some people modified Promaster snubs with powerfeeds to address the problem.
Another common problem which plagued the early guns was a recurring refusal to re-cock. It did not take very much change in the weather to throw the gun completely off. Part of this problem stemmed from the fact that the Promaster was so tunable. It has a valve that could be rotated to position any of four different size holes to the top, where gas transferred to the bolt – it has a tension adjustment for the main spring, and an adapter which adjusted the valve spring – and it had valve pins with different amounts of flat sides for controlling re-cock pressure.
Problems occurred when the velocity was off because of a change in gas pressure (temperature). It could be a very frustrating experience, and I saw several of my friends sell their guns following a tournament in which they could never get the guns to properly function. I liked the way the gun shot and was determined to make it work. The Promaster was designed much like older pump guns in that it had a tiny gas feed hole going into a relatively small valve chamber. That meant the gun required high pressure to operate. The gun used a limited volume of gas to both propel the ball and re-cock the bolt/hammer. In warm weather this was not a problem. An abundance of pressure easily overcame the volume deficiency. However, in cooler temperatures, anytime you adjusted one of those functions, you noticeably affected the other. For instance: you could change to a larger valve hole for higher velocity, but then the gun would not re-cock, and when you put in a different valve pin to make it re-cock, your velocity would drop again.
Some people tried to overcome the problem by shooting liquid Co2 in cooler weather, but this lead to ball feed “blow-back” problems (as mentioned earlier). My solution was to basically make more efficient use of the available pressure. I did this by lengthening the slots on the valve pin with a dremel tool, working on the theory that not enough of the available gas was getting to the hammer for re-cock. This is probably the single biggest improvement I have ever made to the gun. It instantly eliminated my cocking failure problem, despite the weather. However, achieving a usable velocity continued to be a problem in cooler weather.
For about a year, I ran one of my Promasters on my 4500 psi HPA system. The gun required nearly 1000 psi to function properly and recharge quick enough under rapid firing. It worked very well but was not extremely efficient. From a 3000 psi fill on the 68 c.i. tank I would be lucky to get 400 to 500 shots, which is much lower than the 700 to 800 I’d get from a 20 oz Co2 tank (unfortunately the field I played at could not fill beyond 3000 psi at the time).
Since a need for higher operating pressure was the main problem this gun faced, I experimented with several methods of lowering the operating pressure. The trick to that, like on all paintball guns, is of course to improve the airflow. Some access to improvement was available through the multi-hole valve and changing springs, but none of this proved very effective. In fact if it was that simple I would have figured it out years ago. The problem remained that no matter how good the air flow, there simply wasn’t enough air to flow without starving the system. The valve chamber needed to be larger.
One of the earlier experiments I tried for enlarging the valve chamber area involved the use of the body from a WGP Sledgehammer low pressure regulator – the type that used to come stock on Auto-cockers. Amazingly it threaded right into the front of the Promaster, and other than removing the regulator parts, only required plugging the relief holes with set screws. The seal is not as reliable as I would like and requires a combination of an O-ring and lots of pipe tape. However, it at least works good enough to demonstrate that enlarging the valve chamber is a step in the right direction. When I first tried it, I found I could get fairly usable (mid 270s) velocity using as little as 600 psi. For a Promaster, that was nearly miraculous.
Eventually, I discovered that valve chamber extensions made for Spyders would fit the Promaster (imagine that!), although some models require some large amounts of pipe tape to seal properly. A large Shocktech volume chamber combined with the Taso high-flow valve/valve pin also made for a Spyder (which simply drops right in) offered a great improvement in the ability to move a larger volume of gas through the system.
I have made a number of modifications to my Promasters over the years that were not aimed at eliminating problems, but merely at improving performance or usability. Some of the modifications were made after seeing other Promasters, so these are not necessarily original ideas, although I did them myself.
The trigger on the Promaster was probably the best on a semi-automatic of it’s time. It was far better than the F-1 Illustrator ( I have owned 2 of those). However, it could be improved with two small set screws. One screw goes into the body just above the forward part of the trigger, while the other goes into the grip frame below the forward part of the trigger. These screws can be adjusted for take-up and over-travel and give a very short, crisp action. Warning: adjusting the over-travel screw too far can cause a full-auto response. While this may sound attractive, the gun cycles way too fast to feed paint in anything except liquid form.
The rear velocity adjuster for the Promaster is inside of the ASA. This means the Co2 bottle has to be removed before adjustments can be made. I have tried several methods of re-routing the gas feed so I didn’t have to remove the bottle just to get to the adjustment. My first idea was to re-route the gas into the front of the body by drilling and tapping a hole for a 1/8 inch NPT hose fitting. This was convenient for using a bottom-line type adapter. At times I also put a 45 degree elbow in the hole with an ASA on the end and used it as a vertical bottle gun. This modification lasted for about 5 years, until May 1999 when the threads gave and hose blew straight out. I guess years of swapping fittings finally took it’s toll. I recently drilled the hole a little deeper and again tapped it – I hope is holds for a while.
The next idea for re-routing the gas input was the addition of a vertical bottle adapter. I got this vertical ASA one from Indian Creek Designs. It requires the drilling of three holes, and the tapping of two of them. The center hole for the gas inlet must go completely into the valve chamber. Note: Although Indian Creek Designs is known for an entirely new line of guns, they did at one time carry Promaster parts. Once another route for gas was established to the valve chamber, the rear threads on the ASA were no longer needed – so I cut them off and polished the end. The modification requires that the rear ASA air passage be blocked, which is a simple task of tapping the air passage and inserting a set screw. This gave the gun a somewhat shorter profile. On a side note, the first production Promasters had the purple finish seen on the body of this early model.
The Ultimate Promaster?
Unlike many of the guns in my possession over the years, the Promasters were not simply “loaners” or experimentation pieces. They have served as my main guns and have both been through thousands and thousands of rounds of paint, both in rec, tournament, and scenario play. Even when I owned an AGD Minimag, the Promaster was still my first back-up and often used. In warm weather, I preferred the Promaster over the Minimag because of it’s ability to be incredibly accurate without being paint picky. Not until I acquired a PPS Blazer did I actually semi-retire the Promasters… or so I thought..
At a recent 24 hour scenario game, I aquired yet another Promaster (my fourth) and began working on what may be the ultimate version of the gun. The unique thing about this example was the snub. It was one of a hand full modified to have a powerfeed. At the same time the snub was also threaded to receive WGP Autococker barrels. For the low price of $50 (which included a stock barrel), I couldn’t resist.
The gun suffered the same familiar problem when I got it, and in fact would not even re-cock the day I bought it, despite a temperature in the mid 70’s where I was playing in Florida. A quick run over the valve pin with my battery-powered Dremel tool and changing to a softer valve spring solved the problem. I was able to use the gun that day and thoroughly enjoyed it, although overall velocity was somewhat low. When I returned home I installed the TASO valve and valve pin, and a Shock-tech valve chamber extension which put the velocity up past 350 fps, despite colder weather (it had just snowed that weekend at home in Tennessee while I was away in Florida). A spring change and a regulated Co2 source brought the velocity down to legal limits and the gun hsa since functioned flawlessly.
With the addition of a .45 grip frame, sight, foregrip and Dye Barrel, the gun was ready to rock. Personally, I just like the way it feels, which seems to be much more solid than today’s lightwieght cookie-cutter blow-backs. I also like the back-bottle set-up, which adds to the overall comfort, and gave me something useful to do with my one Co2 tank that has a built-in regulator/valve. This configuration worked well, but was a little to bright and flashy for my taste..
The latest incarnation of Promaster #4 has all of the Spyder parts, 16 oz. anti-siphon Co2 tank with CMI regulator/pin valve and an ever increasing amount of politically incorrect cosmetic work, including an actual M16/AR15 forgrip. It also uses the powerfeed snub and an older WGP Sniper barrel which had a 1-inch OD. I turned the front end down on a lathe for the cosmetic effect. These pictures of the gun show the “carry handle” and “flat-top” versions of the the gun. I have used this gun frequently throughout 2001 and it not only continues to work great, but has never needed anything more than a slight adjustment to the CMI regulator to account for the varying limits at different fields. It’s also a very easily pointable (?) and comfortable feeling gun in this configuration, as well as being just plain fun because of the looks it receives.
Meanwhile Promaster #1, which was modified with the vertical ASA and can be seen elsewhere in this article, has been converted and re-painted for use as my gun for night time scenario play. It includes the additon of a nightvision scope, a Palmer Stabalizer regulator, a rear cocking bolt from a Scorpion (a Spyder clone) and a few other accessories. Unlike the #4, this one has the stock Promaster valve and valve pin, since attaining what would normally be considered a “usable” velocity isn’t important for night play, where limits are lower. It also has the WGP regulator body for a valve chamber extension as described earlier.
The morale of the story here? If you have a Promaster which doesn’t function, thank Kingman for building such a nice copy. Because of the success of the Spyder, many aftermarket parts are available which can turn a finicky Line SI Promaster into something that actually works – and works well. Not only that, you can have a lot of fun as people at your local field try to guess what kind of gun it is, and try to argue that it’s just another Spyder copy.
