I'm putting a sniper-style AR (20" barrel, 14" length of pull stock, SPR pistol grip, free float, heavy-duty optics mounts, 10x scope, etc.) and I'm interested in using the Bushmaster DCM barrel. My question is this: has anyone ever tried this barrel on a scoped rifle to determine its full accuracy potential (Jarrod, are you listening?)? One other thing - I also plan to use the BMAS 3 rail gas block and flip-up front sight; is the DCM barrel cut to use taper pins for gas block attachment?
Thanks in advance!
