have always wanted a pump marker even since I got into paintball. But when I got into paintball, the pump markers weren't the only option for markers anymore, semi's and electros where the new game. But the pumps were still the favored choice for players. Which meant that they were still expensive. Too expensive for me, and still too steep for me these days(about $500 too expensive).

Well, one day I decided to make my own pump. I had all the parts and the know how, so I set off to build one. The project gun was my first marker I ever owned, a Brass Eagle Stryker. (link to the original look) Brass Eagle Striker Semi-automatic Paintball Gun | Overstock.com

I started with some body work, removing body lines, chopping the feed neck, just little things. Then came the camo job. A simple, rough woodland camo. Then it was off to the internals. I had to do some bolt pin work because the stacked tube format had a single pin that connected both bolts together. I had to have both bolts cock back, but have the top bolt slide forward to load the ball into the barrel, while the bottom hammer bolt stayed cocked. This was done by making two pins(one for each bolt) and having them connect together by half notches in each pin. This would allow me to cock both bolts back and then slide the top bolt forward while having the hammer bolt stay put. I also had to extend the top bolt to allow the connecting rod to the pump handle to connect. That was done by threading a bolt into the rear of the top bolt. I filed off the threads and polished it up for looks.

I also had to make a new valve pin because the stock pin had notched in it to allow air to leak by.( yes I could have filled in the wholes with JB weld, but I wanted to make a new one anyways.)

The barrel was also made by me. It is 3/4 CPVC pipe. It is a 12 inch ported barrel. The ports are 1/16 inch port holes. The Strykers did not come with threaded barrels, instead they came with glued in plastic barrels. I removed mine, and now the new barrel is friction fit in place. So far it works nicely, and the ports reduced about 30% of the noise( as oppose to no ports). And the pump handle if from a wamlart pump that I pulled from the trash.

The stock is box aluminum. It is two parts, the rear shoulder piece and the strait part/drop forward. It was specifically made to only fit a long 9oz or smaller tank. The ASA is an on/off ASA held in place with a high rise scope mount, and is plumbed with macro lines. And the hopper is 50 round loader.

There is still a lot of work to be done to it. I have some more painting to do, and some spring tensions to work out. But here is what she looks like so far, enjoy

You know what? I haven't been on in 4 years, but this is the first good post I've seen since I got on today, everything else is the same crap...what's the best barrel, what's the best marker, somebody build this for me because I'm too inapt to do it myself, etc. I congratulate you, it actually looks somewhat like a high end pump. You sir, rule.

Dont complement me to much, I'm liable to get an ego bigger than my head right now

This project has been sitting in my room for quite some time and its caught my eye more than once these past few weeks. I had problems with making the lower hammer only fire once (and not re-cocking) but I think I've come up with a solution. I though it was because a spring tension issue, but now I think I've found a way around it. I need to make a new hammer, one that has vent holes to vent off the extra pressure and to keep it from 'farting out' after each shot. It functions properly like a pump, but some air is still slipping by and is causing the hammer to sputter out instead of just firing and staying put. I tried drilling out the original hammer but that crap is hard sh**. once I make a new hammer I should be in business.

I did get the painting done (painted the stock) so I'll have to get pics of that up. No promises...I'll try to get some pics up this weekend.

Oh and look me up on the 98OG if you haven't seen me there already.
