The HHQEV

[Terrible]

this is my second cannon i built. as you can see its just that (Hand Held Quick Exhaust Valve) with some assorted pipe fittings and an old 9 0z co2 paintball tank.

I have 2 barrels 1 is 1/2 inch x 44 copper pipe for AA batteries and a 3/4 x 30 for mini potatoe slugs

Nice gun indeed but I have one question. Is that a sprinkler valve because it looks like it from this angle. Simple and great.

Thanks... no its a 3/4 Quick Exhaust Valve works great!!! I know the valve is rated for 125psi has anyone pushed it passed that without any problems?

i believe it is rated to 150 if it is deltrol, and if it is i wouldnt push it past that. i think 150 is the safe # for these kinds of valves. try largening ur chamber for better performance

i've taken my QEV cannon past 200 using a compressor at a friend's dad's shop. No problem at all, but I wouldn't recommend it.

Very nice gun, and i like the stock.
