so who makes the best quality 9mm ar? I was thinking about getting one. I definately want a factory 9mm gun - I don't want to convert my only AR and have to mess with switching back and forth as I shoot my 5.56 quite often so it's just easier to have two rifles. I know Colt made some of them, but those seem to be hard to find and very expensive. likewise I read that the olympics are pretty shoddy quality. Anyone have any experience with the products from bushmaster, rock river, or other makes? Anyone with first hand knowledge to share it is greatly appreciated.
