Re: Rookie AR Question...
While there are some minor differences in chamber/cartridge dimensions, my AR15 (Bushmaster CMP) and my Ruger Mini 14, will both digest 5.56 milsurp and commericial 223, without any problems.
I've shot several kinds of 5.56 in the Ruger for years. It also likes bulk pack Ultramax 223 ammo, which is all reloaded in military Lake City brass. So is Black Hills ammo, if not mistaken?
I would contact the manufacturer of that AR, to see what they say.
