Cut Down SBR Barrels
I have a Colt 6920 that I'm registering as an SBR. I was wondering how reliable my upper would be if I had ADCO cut it down to 11.5" and open the gas port if needed? Has anyone else done this and had great results? I'm not questioning ADCO's work, but I would like to know if buying a stock BCM 11.5" upper would be more reliable? I don't want to end up with something that's going to be finicky when I could've just bought a reliable factory upper from BCM.
