I'm sure this has been asked before, but I couldn't find it. How exactly does the action of the bolt assembly function on the pistol caliber ARs? Is it recoil action, or something else. Does this require a specialized bolt carrier, and bolt assembly? I'm interested in building a .40 or .45 caliber AR, and have no idea where to begin researching it. I currently have one SBR AR15 under my belt, and like the idea of a pistol round for a SBR. Any answer's and information will be greatly appreciated. Thank's SweatyBlue |
