How about a multi barreled gun that has a single chamber and valve with a big manifold to attach barrels to?

well can you make it look like an M14 with the chamber on your gun being analogous to the gas piston on the M14?

A double chamber makes it bulky. how about a longer chamber slightly larger? Keep it sniper looking.

Have fun!
BTW
I have access to bunch of copper pipe and fiitng and I want to build a Sniper with it. What does your barrel sealing piston look like? If you dont mind sharing a pic or description would be nice.

Thanks

ull see it on my comp gun..well the outside.. inside is a teflon machined piston fitting almost perfectly with 2 equilization grooves that are 1/32" and 2 sheets of neoprene bolted to the front and the back with a grinded put bushing so the barrel slides halfway through
