[QUOTE="ColtDogg, post: 2634107, member: 2862"] On my Colt RR I had , it had the M4 Commando 11.5 upper on it. Ran like a top with the m4 2000 can on it. The upper was factory with a FSB. Now I got a Black Rain full auto lower I put together with a YHM 10.5 barrel, and a the adjustable gas block from Black Rain, and it's a nice set up. The adjustment screw has its own detent and will not back out. [/QUOTE]
