BCM barrels use 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. Receivers are machined from aluminum forgings 7075-T6 and Hardcoat Anodized per MIL-A-8625F, Type III, Class 2
