Brownells Brn-180
The 16″ barrel is machined from extra-strong 4150 carbon steel, with a hard Nitride finish that really resists surface wear. The BRN-180 is chambered in .223 Wylde – for extra flexibility in ammo choice – with 1-8″ rifling, so it handles both .223 Remington and military-type 5.56mm NATO ammo with equal aplomb. Up front there’s a replica of the AR-180’s unusual three-prong flash hider: the hemispherical bottom prong helps prevent the muzzle blast from kicking up a dust signature when shooting prone. Standard ½-28 tpi muzzle threads let you swap on a modern AR-15 muzzle device should you be bitten by the customizing bug.
