Barrel Profile.
11595E.
Running a 20" barrel with a 1/7 twist, 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.
HPT & MPI.
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.
