anything, just as long as it's not really bad dimpled paint.
Accuracy, accuracy, accuracy, and it can shoot through breaks pretty well too.
i got this barrel used online, since my brother got a cp one piece and said it was great and for 5 bores and 2 fronts it was a great deal. when i shot it i couldn't believe how accurate it was, especially since i had been using a freak for several months. the interchangeable backs are much sturdier than the inserts (on the other hand with inserts you only have to buy another back if you switch guns instead of a whole new kit). the backs have o-rings at the tops of the threads to stop them from unscrewing, which works, and yet despite the fact that i've got an autococker, which makes unscrewing barrels tough sometimes because of the front block, it's never gotten stuck on my gun. this thing is the most accurate barrel i've tried, better than the J&J Edge that came with my gun and better than my freak. also, with the freak if you get paint in it no amount of firing will clear the barrel out at all, the cp shoots clean much more easily. you've still got to squeegie it out, but it won't destroy your chances in the middle of a game.
This gets a 10 out of 10. Best accuracy i've ever seen, shoots clean fairly easily, and even though i got this used after trying it i would buy it at retail price, it's definitely worth it.
