I have everything in the drawing above assembled and the m72 tube gutted but i just cannot get the piston valve to work. I made the piston out of a 1" pvc cap wrapped in duct tape with a piece of gasket material to seal onto the inner barrel. http://i318.photobucket.com/albums/mm435/Martyr_Maker/100...

I wish you luck. Im working on a demilled m72 with coax internals right now but its been kicking my ass for the last couple months.

First off, thank you all for the advice. I really appreciate the help. Second off, anybody attempting to do something similar to this with an inert m72 I want to warn that it is EXTREMELY difficult! Now to the issue at hand. I went the coaxial route that was suggested early on. http://i318.photobuck...

its actually around 66mm. The 2" pipe fits in fine but the fittings do not. That, among other things, is the biggest problem spot.

just needs to shoot out the mini vortex nerf rockets. We use them to take out bunkers, vehicles, or just lob them like a mortar with a 15' kill radius.

ok i finally had some time to work on this project but its a lot harder than i thought it would be. I only have 22 in. of space to work with and 2" fittings do not fit inside the tube. Both the toolies valve and coax set up are giving me problems because i do not have enough room for a schrader valv...

Thanks for the welcome! i searched around prior to posting this thread, the only relevant thread had a bunch of ideas but nothing conclusive. The guy who started the thread was building the entire thing from scratch. body, internals, everything. This gave him the ability to scale everything up. That...

ok guys im really excited. I just secured an inert m72 law tube to use for airsoft. For those of you who don't know what an m72 is.... http://world.guns.ru/grenade/m72law-2.jpg So now its time to start figuring out how to get it working but i really don't know where to start. It needs to use the 12g...

aha finally something on this forum i know a little about. :shock: http://steelhawkairsoft.com/mb120.html The launchers use a shell that is filled up with green gas, baisically propane with silicon added in. The shells have a pressure plate on the back and the trigger is hooked to a firing pin. When...

i was thinking about doing something along the lines of an AT-4 or a LAW sometime after i got all of the bugs worked out of this version. But i haven't put too much thought into it as of now. Thanks alot guys i really appreciate it. Ill probably start making the changes everybody seemed to agree nee...

well the C02 kinda creates a problem for me because most of the airsoft fields dont allow C02 in custom launchers. The only other gas besides compressed air that can be used is HFC134 or "green gas" which is basically propane. Nice thing about air is it is free so i prefer it.

ok so then what can i do as far as removable tanks if i ditch the ball valve?

Hi everybody im kinda new to spud guns so I was wondering if you guys could give me some advice on one i have been working on for a month or so that shoots out the mini nerf vortex rockets, 2" barrel. The project was intended for use in milsim airsoft so some of the concepts I wanted to have impleme...
