Exacting construction and rigorous durability are the standard for every weapon system that comes off our line. BCM® Professional Grade Weaponry® are hard use tools, built to perform in combat where unfailing performance is the only standard for men and machine.
BCM® M4 carbines come stock with a carbine length gas system, as designed and fielded by the US Military in the XM177 carbine. The BCM MID16 series and BCM Recce series are offered with a optimized mid-length gas system, while our 9" 300 Blackout uppers feature a pistol gas system.
Utilizing either independently certified 11595E Mil-Spec barrel steel or SS410 stainless barrel steel, are more durable than typical commercial barrels and specced to perform under heavy use in high-threat environments in extreme temperature conditions.
Every chrome lined BCM® barrel is subjected to the Mil-Spec HPT(High Pressure Test) and then MPI (Magnetic Particle Inspected) to detect any possible flaws in the barrels surface, guaranteeing a more durable weapon.
