The blow forward bolt definitely works and is relatively easy to build:



What projectiles are you looking to fire though?

i was thinking paintballs or rubber paintballs

This is a simple pneumatic mechanism I made. Just uses a 3 way roller mechanical valve and a QEV. I need ideas on a working bolt so if you have any plz lmk.

It would help to know the mechanism you plan on implementing. People have had success cutting the back of the barrel with a hacksaw and slipping an o-ring over the groove as a detent to keep the ammo from rolling out the front of the barrel, but it doesn't stop the BB's going the other way. Thank y...

I have an old airsoft gun barrel and i want to make some blow black breech mechanism but the bbs keep rolling out of the barrel, any ideas?

Hi i made this airsoft "rocket launcher" it is essentially a giant shoulder mounted shotgun made out of a sprinkler valve and some pressure rated pvc pipes. I only pump it up to about 80 psi due to the risk of the pvc exploding. For the shell i use a 3/4 schedule 40 pvc pipe with a bunch of bbs insi...

An idle thought that is basically the unholy marriage of a nailgun and paintball marker: https://i.imgur.com/LqY0rAO.gif The benefit is that it will fire whatever fits in the barrel and it doesn't need to be airtight, indeed it could be fed though a hopper of shot of whatever size doesn't fall thou...

Hi I've made a very powerful pneumatic gun based on a piston valve. It looks ugly but it's a prototype yet, because i don't have enough money and needed tools now to finish it. But it still shoots. Tested with paintballs and 15mm steel balls(barrels are exchangeable). I've been able to launch the p...

6mm airsoft BBs and 1/4 ball bearings fit nicely inside of a 5/16 metal brake line. With the ball bearings use a magnet to hold them in place.

Hi i am looking for easy to get ammo that will fit nicely inside a schedule 40 pvc pipe. Something easy/cheap to get that can do a decent amount of damage to a target, Thanks.

Nice work for a first build! Looks like the first shot hit head-on and the second shot hit sideways.

Any reason you're shooting at night?

Thank you! I was really busy that day so the only time i to shoot was at night.

What is that 3 way valve with the lever called?

to watch the shooting test there is a link in the post

One of my first launchers was a battery launcher. I used sprinkler valves with battery operated solenoids. Performance was garbage, but it was fun. It was a fun thing and you also have a fun thing. I'd like to see yours work. I also had a sprinkler valve powered air gun for my first pneumatic launc...
