Good: This is an accurate barrel and if into the whole military looking thing....it looks military with muzzle break.
Bad: Very oud, but loud has never bothered me. It has no range waht so ever. The reason? well with the rifling there are spaces in low parts of the rifling...there for u loose alot of velocity...this sux..really bad. also...with the spaces, it means u must have larger paintballs.
over all i didnt like it at all....the whole range thing made me mad. But note, when i used this barrel i was using a pirrahna. But over all...i wouldnt recomend it. I took the barrel back and got a J and J ceramic.....love it. Smart parts and dye barrels are better
