Airsoft "rocket launcher"

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...

Re: "Sabotless" Semi-Automatic Shotgun Concept

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...

Re: 150 bar 15mm caliber piston valve beast

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...

Airsoft/ 1/4 ball bearings

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.

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.

Re: Battery Gun

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...
