A simple/quick over-under pneumatic.

A simple over/under pneumatic. Modded 3/4" sprinkler valve, 24"x2" chamber, 36"/2" barrel, quick-connect filling and another T-stock, which I'm a fan of. Not going for power or distance, just something fun/relatively quiet to play with, maybe sent some retrieving dummies to play fetch w/ my friends' dogs. I'd say it's not bad for an evening of TV watching. With some silver paint, it'd almost look like a prop from MIB

That looks like a clean build. Good job. I'd like to see it after you've painted it.


Im glad you said you weren't going for power, because some non-efficient things almost hurt my eyes. (Im more of a performance & power guy):
- That stock, I hope that it isnt connected to the barrel and blocked off inside? It would cause the dead volume which is already quite big to become ridiculously large.
- The zig-zag after the sprinkler constricts flow and adds dead space. I have to admit that it adds to the cool looks.
- The big T piece could've been an 90* elbow. Less dead space. But again, it may look cooler the way it is now.
- Your blowgun is mounted in reverse. It isnt meant to be pressurized that way and may leak (and thus cause accidental triggering)
- Your valve porting and pipes to the barrel are lower in diameter then the barrel. Not very optimal, but acceptable for a non-performance gun.

Above criticism can be ignored, but I just had to say it, for if you decide to make a more powerful gun some day.
