From the renowned manufacturer BCM, this 16″ 5.56 NATO barrel is constructed from professional grade 41V50 chrome moly vanadium steel. This superior quality steel offers outstanding durability, making it ideal for extended use. The chamber and bore are lined with chrome, providing protection against fouling and corrosion. This ensures a longer barrel life with less time spent on maintenance and cleaning.

The 1:7 twist rate of this barrel allows it to 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 to 70,000 psi and then magnetic particle inspected to detect any possible flaws in the barrel surface.

This is a high quality barrel that is perfect for those who demand the best in terms of performance and durability. With its superior construction and attention to detail, this BCM barrel is sure to exceed your expectations.
