I asked this in the Industry forum, but I figured I would get an answer quicker over here, so..are Bushy M4 16" barrels in good supply? Im not interested in the 14.5" with the Y comp, or the full upper. Im trying to wait on a Rock River chrome lined, so I can give Pete in NH some business, but Im too damned impatient. If anyone knows if they are available, couldya lemme know? Thanks.
