The one I had, basic 16" A3, ran fine and dandy for me- guessing 400-500rnds. Then I traded it to my Chief and he reported no problems, but I don't know how much use he and his kids got out of it. It came back to me and I put 120rnds through it before my son ran off with it (actually, I gifted it to him), and he's reported no problems from it. I do hope he's keeping it clean.
It was always my opinion that it was just as well made and finished as anything in the line of DPMS, Double Star, RRA, the older Bushmaster I have, and my Olympic lower. And when it was brand new, it had a less sluggish break-in than my R-Guns upper, which cleared up well enough to haul to a HP match after 40 rounds.

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
