VERY DURABLE AND RELIABLE. Used as a back up gun to my bushy, and the only thing that has ever broken on it was the sear spring. The stock barrel, the zero-gravity, performs very nicley. I personally am a fan of single finger triggers, so this makes me happy. . Just dont use crappy paint.
Trigger pull is a little tight, but if you know how to lighten springs it'll be fine. I can't think of anything else that I don't love about it. If you use crappy paint, be warned, it lodges between the bolt and body and is a biznitch to clean out.
A great gun at a great price. Can't be beat for durability/performance.
