Comes fully assembled with all sub-components installed, including firing pin/spring/retaining pin, extractor, and extractor spring.   Also included in bolt assembly is a propriety center and roll pins.  Our 45 bolts incorporate our new bolt design which caters to single stage triggers with short resets.  It also allows use with the JP silent capture spring but is not recommend for 45acp applications.  This bolt is compatible with the Law Tactical folding stock and the Echo trigger.

    Outstanding Quality

    Posted by Matt on Mar 18th 2024

    I now own all three of Stern's PCC NiB BCGs. All cycle smoothly, are weighted properly for function, are much easier to clean than other finishes, and look great in the carbines. Highly recommended!

    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.
