well this is my first decent piston the first one sucked so much i mean like it had a good bumper but the piston deformed its self after the 20th and wouldnt fit no more so i got pissed and decided to make a new valve, i dont think this should belong in the cannons showcase cause, its not a cannon
this piston is going to be for my 2 inch tee 1.5 inch porting. the sealing face is the middle section of a toilet plunger very think stuff man

the back is held in with a old pressure gauge i took apart fits very well in the 1.25 coupler. the rubber from the toliet bowl plunger should seal well i hope, do you guys think it will?
