Toolcraft 5.56 NATO Black Nitride Bolt Carrier Group - Carpenter 158 Reviews

4.9 Rating 291 Reviews
I bought a Toolcraft black nitride BCG, coated it with a light touch of CLP. Dropped it into my PSA upper and fired away. After 100 rds, I pulled it and found it still slick and clean. I'm sold!

My 1st nitrided BCG. I'm very happy so far. I love the nitride treatment over regular phosphate/park. Also love the fact iits a hp,mp tested C158 bolt. Gas key staking is excellent and shipping was xtra quick. Already put 1500 rounds on it and no problems at all, and zero wear marks surprisingly, not even on the top rails. Also much easier to clean than a phosphate coated. I will shop Monmouth in the future and recommend to folks for sure. Shop here with confidence.

Very pleased with my first order from MMR. Best price online, shipped fast and well-packaged. BCG is super-nice with a beautiful finish. Bought to replace a returned BCG from another vendor that I've used before, but quality had fallen off. No such problem with the Toolcraft--will buy again!

Bolt carrier works as advertised. Coating is super slick and the finish looks great. Have had it out to the range a few times and has performed flawlessly. Would highly recommend for the price and would buy from Monmouth Reloading again.
