The BCM 14.5″ 5.56 NATO Barrel is constructed from 41V50 chrome moly vanadium steel for superior strength and durability. These barrels are crafted through cold hammer forging to produce the most accurate, longest lasting barrels available with a more consistent chamber and bore. The chamber and bore are chrome lined adding protection against fouling and corrosion, ensuring a longer barrel life with less time spent maintaining and cleaning. A 1:7 twist rate ensures that this barrel can stabilize heavier rounds preferred by most professional infantrymen for their superior ballistics. M4 feed ramps increase reliable feeding while dimpling at the gas seat allows precise gas block installation. All BCM barrels are proof loaded and test fired prior to shipping to ensure the highest quality product makes it to your door.
