Can this be done and maintain reliability? I dont really see why not as it would seem to be similar to a 10.5 with a carbine gas port. I'm asking as I have a spare 16in BCM midlength barrel and I'm in the process of starting to build my first SBR. If it can be done I think it would make for an incredibly sweet shooting, unique and practical rifle.
If done the setup would be
-12.5in Midlength BCM Upper
-Larue 11.0 Rail
-Surefire MB556K and Surefire Mini
-Aimpoint T1
-Troy BUIS
Lets hear what the experts say...
