    Excellent

    Posted by Kyle Gregory on May 15th 2020

    I am pretty dang impressed with this BCG. For being phosphate, it's incredibly smooth. The staking on the gas key is well done. The direction arrow on the cam pin is a nice feature. The extractor and ejector springs are incredibly stiff and should last a long time. For the price, it easily beats $200 bcgs I've had. Buy with confidence.

    Superb

    I'm normally not the type of person to write reviews, so the particular product or service I'm reviewing truly has to be exceptional. This BCG is exceptional. Zero tooling marks, deep/fine finish, excellent staking, and clean chromed interior. If I ever need another BCG, I'll be getting this one. Fantastic product!

    High Quality mil-spec bolt

    Posted by Bill Bronaugh on Oct 17th 2019

    Checks all the boxes. Double staking on both gas key bolts, thats nice to see. MPI tested naturally. At least on my sample, I see great machining. It actually has a very nice surface, nicer than my BCM bcg's and hell, theyre pretty nice BCGs.
    Besides being a top shelf BCG, I really like supporting people like Centurion Arms, they are some of the nicest people Ive done business with.

    Quality BCG, great value

    Posted by Brian on Aug 10th 2019

    These are a great value for a quality, reputable bolt carrier group. I actually appreciate the absence of an HP test on these as it seems HP testing only manages to decrease bolt life with little benefit to quality control. Overall a great option for a hard use rifle.

    A BCG that Delivers!

    Placed in an upper receiver that needed some attention to detail after purchase. I found that the SRC with DLC worked the best with this upper.....until Now! Centurion Arms BCG just works, cycles smooth, looks good, and the price is awesome! Keep making affordable, high quality
    product, and i will
