Helpful Positive Review It’s Parkerized. Again, it’s Parkerized. But not bad after some oil. by Andy, Verified Owner, July 8, 2023
I knew the finish would be Parkerized. I think some people don’t understand this model is. The Parkerized doesn’t come with a Wilson combat logo. No markings on it. Just a plain jane BCG. But if Wilson Combat stands behind it I have to imagine it’s q...

Product Info for 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 BCG 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.image

No matter what finish works for your needs, these bolt carrier assemblies are drop-in-ready and feature a staked gas key. You are ready to go with just a few clicks. Improve your AR-15's action and recoil from the moment you pull the trigger.
