    NIB Bolt

    Posted by Eric on Jun 24th 2023

    The quality is top notch. NIB coating is great. It is very slick and easy to clean. Got this one over the standard because I will almost always shoot suppressed, and NIB is much easier to clean. Plus as it gets dirty it still stays slick. And it really slings the spent cases out with authority. With the 11oz buffer it runs very well.

    .45acp NiB Echo BCG

    Weighted right. Runs great- also in other manufactures upper/barrel. Glock mags feed & cycle spot-on. Highly recommend this BCG over all others.
