Wilson Combat Bolt Carrier Assembly

When you're building your AR-15, the most crucial part is the bolt carrier assembly, and the Wilson Combat AR-15 Bolt Carrier Group is a perfect choice! The Wilson Combat Bolt Carrier Assembly comes in several different finishes depending on your shooting needs: nickel boron, black nitride, and parkerized. Nickel boron offers resistance against corrosion and increases lubricity, which makes the bolt carrier easier to clean. Parkerized Bolt Carrier Groups have a manganese phosphate coating that increases the thickness of the bolt carrier. The black nitride coating is very durable and resistant to corrosion while having a smooth finish for easier operation.
