I'm going to be welding an AAC Ranger 2 onto an AR barrel. I know it's sub optimal but SBRs are simply not an option in Washington state. I have two options, a cut down Colt barrel, and a cut down 14.5" MRP barrel. Both would be approx. 10.75" long.
I'm assuming I don't need to modify the port in either. What buffer do I need? H3? I doubt I need an X as Colt and SAW open the ports in their dedicated suppressed rigs, or so I hear.
Has anyone here gone this route before me?
