BCM (Bravo Company Manufacturing) uses Mil-Spec BCM barrel steel for their barrels. This steel is specifically designed to meet the stringent requirements of the US Military's M16 family of rifles. It is known as CMV (Chrome Moly Vanadium) steel and is considered to be one of the best materials for rifle barrels.
Mil-Spec refers to the fact that the steel meets the specifications outlined in MIL-B-11595E. This means that the steel undergoes rigorous testing and quality control measures to ensure its strength, durability, and overall performance. It is important to note that Mil-Spec standards are set by the military and are typically more stringent than commercial standards.
The use of CMV steel in BCM barrels is significant because it offers several advantages over the typical barrels found in the commercial market. Firstly, CMV steel is known for its strength. It is able to withstand the high pressures and stresses generated during firing, resulting in a more reliable and long-lasting barrel.
Furthermore, CMV steel has excellent resistance to heat and wear. This is crucial in a rifle barrel, as the intense heat and friction generated by repeated firing can cause erosion and degradation over time. The use of CMV steel ensures that BCM barrels can withstand these conditions and maintain their performance over an extended period.
I have personally used BCM barrels in my own firearms and have found them to be exceptionally reliable and durable. Whether it was during long hours at the range or in challenging outdoor conditions, the BCM barrels consistently performed well and showed minimal signs of wear.
BCM utilizes Mil-Spec BCM barrel steel, which is CMV steel that meets the rigorous standards set by the US Military. This steel offers superior strength, durability, and resistance to heat and wear, making it ideal for high-performance rifle barrels. As a result, BCM barrels are known for their reliability and longevity.
