About this product
This M27 inspired barrel is built for Brownells' BRN-4 upper and also fits HK416, MR556, MR556A1 and MR223 pattern uppers. It is 16.5" long with a medium contour, a 1-7 twist and a chrome lined 5.56 NATO chamber, finished in manganese phosphate.
The muzzle is threaded 1/2-28, so an A2 style flash hider or most common AR-15 muzzle devices thread right on. A forward bayonet lug installs after the gas block, held by a cross pin. Brownells calls for its BRN-4 16" gas block with this barrel.
