They were cheap and they were light. Good? Dunno if I'd go that far. The only one I owned was a 28 ga. O/U but I've handled the SxSs and other gauges of O/U. They looked nice to be honest but the fit wasn't as good as it looked. It was so rough that I had to use lapping compound to smooth it up so it would open and close.
I can't say for sure if it's was just me, the lightness of the gun or what but I wasn't ever able to hit even 50% with it at skeet at a time with I was shooting close to 95% with my others guns. That's all the experience I have with American Arms. Maybe someone else has more.
