one of my friends shot someone with a paintball out of something like this from 200 yards away......................... he has a bruise the size of a basket ball on his side he lucky he didnt kill him. what a moron

for sum reason i agree with drac. my parents have let me build hugh spudguns that shoot water bottles .5 miles. but they wont let me get an airsoft gun or a bb gun!!!!!! it sux but i know what he maens

anyone know what size that barrell is? if not plz tell me what size barrell wilkl fit copperhead bbs thx

im buildin a similar thing, but with a 3/4 inch sprinkler valve. just wonderin how do u thread 3/4 inch cpvc to reg 3/4 inch?

is it cpvc or sch80 3/4" cuz my marbles dont fit at all in my reg sch40 3/4" barrel

well, yeah it was his first combustion and he wasn't experinced enough to know that acetlene would generate so much pressure. so i wouldn't recomend messing around with dangerous toys if ur not experinced in the matter

yah one of the kids my cousin goes to school with decided to try using acetelene/oxygen mix in his new combustion(he had only used pneumatic before that) he ended up in the ER getting pvc shrapnel removed from his stomach :x :x ouch! so i would stick with ether or propane or butane if i were u so u ...

ok thanx alot! no i know that i can make this out of sum scrap i have around my house if it was 2" i would have to go like 6miles to the nearest hardware store ,but i can do it now

hey what size pvc is ur chamber? i dont want planz or anything but i can't tell if the chamber is 2" or 1.5 or what.
thanks alot

yeah, i personally have one of joels' supah valves and im tellin u that it is the best u can get

that is insane i have a crrrappy bike pump in my garage so maybe i can find the parts to make it

i really want to build 1 of those but i cant find the valve on mcmaster!!!!! could someone tell me what category its under or what page its on

by the way my complements on the awesome metal
