Manufactured by Defense Industrial Base suppliers to WMD's exacting specifications to provide the best BCG available, these BCGs are specifically engineered for NiB-X nickel boron coating to provide long life, high reliability and easy cleaning and maintenance. The BCG components are coated and polished to reduce fouling adherence. Coating is guaranteed for life against chipping, spalling or flaking. Over 30K rounds in Government protocol endurance testing did not wear the coating off. Especially beneficial in short barrel setups and suppressed platforms.
