Anybody own or shoot a 9MM AR15? I'm looking at maybe purchasing one and need some feedback before I do. It's a Colt if that matters.

I have shot the Colt submachine gun quite a bit. The only think I do not like about it is that the magazines are hard to load and if you bang a fully loaded one against anything, it will spew out 5 to 8 rounds.

They shot good.

I have a Rock Island 16” 9mm AR. It uses the Colt or modified Uzi magazines. It is a fun gun to shoot. I sometimes use in it 3 gun matches where I expect the rifle targets to be inside 50-60 yards. With a red dot optic it is more than accurate enough for clay pigeons at that distance.

One advantage to a pistol calibre carbine, is some ranges will allow you to shoot them, where you cannot shoot a "real" rifle calibre.

With sub-sonic ammo a supressor is a cool ad-on

It really needs to be a SBR too.
