I have made a heap of these Soda Bottle chambers guns and they are awesome and cheap as hell they look pretty schmick aswell..Nice gun keep on shooting.
I wouldn't be so sure about that...My brother's pneumatic exploded in it's hands, causing major cuts and 2 days deafening. (the bottle had been used for a loong time at 60 psi and exploded at 40) bottles are made for handling pressure of 80 psi in a small area. When it's the whole bottle that is pressurized, it slowly deforms itself, causing little decrease in pressure resistance.
I trust metal since this afternoon when my brother came and said "i can't hear you...i'm cut." and i saw his mouth bleeding, and his hand.
Do what you want to do, but a 2" by 1' of gal. steel pipe is a lot more sure than a plastic soda bottle.
