Each Weapon System - Fully Loaded With BCMGUNFIGHTER Upgrades!

Available in 11.5", 12.5" and 14.5"(non-pinned) configurations, every BCM® barrel uses the same Independently Certified Mil-Spec 11595E Barrel Steel (CMV) used in the USGI M16 family of rifles. Built to perform in extreme environments, BCM® barrels are stronger and more durable than typical commercial barrels, thanks to high concentrations of carbon and/or vanadium in the alloy.

BCM® barrels also undergo a M197 HPT (High-Pressure Test), commonly referred to as a proof load, rating each barrel for 70,000 psi. This hardening is followed by a MPI (Magnetic Particle Inspection) to detect any possible flaws in the barrels surface, with both circular and longitudinal magnetic fields per ASTME1444-01 in the current Military-Specification.


BCM® NFA carbines come stock with a carbine length gas system, as designed and fielded by the US Military in the XM177 carbine. Backed into the rifle length AR gas systems, the carbine length system was designed to be as compact as possible while reliably cycling rounds and maintaining compatibility with the standard M16 bayonets. The carbine-length gas system is still in use, powering stock M4 carbines issued to members of the US Military today.		A chrome lined bore and chamber is now a worldwide standard in the industry for a battle rifle. The chrome bore and chamber is harder than the barrel steel and on the USGI M16/M4 rifles will aid in chambering, extraction, and reliability. It increases velocity, and also resists against fouling and corrosion from extended use in the field. This gives the end user a longer barrel life with less required time in maintenance and cleaning.
