If you are just having fun... do a PSA. Barrel should last you a good long while 3k+ rounds or so. Very cost effective.
If you plan to really abuse the gun get a better barrel. I forget, but maybe it was Shaw?
Couple of friends were bragging on a particular brand holding up very well after 10k-15k rounds. Anyone help me out here?
I do recall the barrel was 3 times more expensive than most.
I'll get back to this after I talk to Chris and Tycen.

I've built a ton of guns with cheap Green Mountain blanks... vast majority of these guns will never see 2k rounds... fantastic accuracy for $100 blanks... they just don't last forever.
