RE: sighting system for pistol caliber carbine.....
Agreed, and you could go out to longer ranges with the .223 Rem. But, since I already have 9MM guns but not .223, it makes soem sense. And also I can fire it at pistol-only ranges, which there seem to be a lot of around here.
Thanks for your advice. Do you have an opinion between the tubed or tubeless designs?
