Nickel boron finish and bolt carrier compatibility

Nickel boron coating resists corrosion and reduces friction where your cam pin cycles through the bolt carrier. This hard-anodized surface treatment extends component life in both dry and wet conditions. The 3.9-inch length matches standard 5.56mm AR-15 specifications. Proper cam pin engagement ensures your bolt carrier group cycles smoothly without binding. For detailed information on California firearms and accessories, visit California-compliant handgun catalog.
