I need help to ID this AR 5.56 barrel. It's 16" long, has a .568" muzzle dia. with a slight counterbore and NO muzzle threading. The top of the barrel is stamped a B (or 8) 5.56 NATO 1/9, and what looks like a crown cast into the gas block. It.s on a Rock River LAR 15 I just acquired[img][/img]http://s143.photobucket.com/albums/r136/dokey1.arbarrel2.jpg

  If it has no lug for a bayonet on the underside of the front sight/gas block it looks like you have a "post-ban" Bushmaster barrel. The no-thread barrels and no bayo lugs were common on guns here in Ca before the ban took place, my Colt upper is set up that way.
