A burning hatred? :shock: Is it really that bad? :wink:

Anyway nice gun, but I bet its louder than all hell with that shorter barrel. So overall length is under 4 foot? Nice and compact.

Where did you get that valve, Ebay? Is it 2 inches and how much of the elusive moneys?

Trying to figure out how to make a SCUBA first stage regulator work for portable charging station. If only that pesky job thing didn't keep eating up all my time...

Details on the valve later... reason why later...

And the length is just under 5 feet. Loud=success in my book!

Sprinkler- $40
Fittings- $50
Pipe- $30 (needed to buy the 3" in 10' sections)
Experiencing the recoil before seeing plywood blown to chunks- priceless

Got the barrel at mcmaster. Go buy it from BCARMS. It's cheaper.

We can't buy from McMaster as they don't do international shipping, and shipping a barrel from the States is expensive enough. Just go to a plumbing merchant and ask.
