If you want the best bolt carrier on the market, you just found it. We custom machine our bolt carrier groups with a focus on tolerance and a unique, aggressive look that also reduces weight. We then coat the entire carrier with nickel boron. This coating gives the carrier extreme lubricity, stops the finish from wearing away with use, and makes cleaning the carrier as simple as wiping it with a dry rag. Simply put, this is the last bolt carrier you will ever need to buy for your rifle.
