Either that or an AR SBR, and hows it running? Im getting ready to build my upper reciever to run as a pistol until my SBR stamp comes in.
Im having a hard time deciding between a 7" or 10" barrel. I really want a 7" barrel but am wondering about operating issues with the shortened dwell time of the 7" barrel. Seems like people are having problems with short stroking due to the limited time of gas redirect.
So, who has what and how does it run? Or better yet, whos ever built their one 7" or 10" uppers and how do they run? Anything I need to be aware of before I bolt this thing together?
