I've been wanting to get a 9mm upper for quite a while. Any info on compatibility to a Colt H-BarII? Thanks.

Please excuse my 9mm upper ignorance…

So have an ArmaLite M15A2. I put a Rock River 9mm post ban A2 upper on it. What do I use for magazines? What do I use to get the magazines to work in .223 magazine well? Thanks guys.

Will the Rock River Arms 9mm upper go onto the Colt Hbar without any problems? Does this require anywork be done to the existing hammer? Any info will be greatly appreciated.
