    Description

    The bolt carrier group is the heart of your rifle so it’s worth spending a little here. This one is mil-spec dimensioned for 5.56 and .223 and it’s finished in nickel boron. That coating is slick enough that carbon wipes off with a rag instead of a scraper and it cuts friction inside the receiver too. Many shooters run these with very little lube. If you’ve ever spent an evening scrubbing a BCG you’ll appreciate the difference.

    PROCESSING & SHIPPING

    Orders typically ship within 1–3 business days (Monday–Friday) after payment and all required documentation are received. Time to arrival after shipment depends on the carrier.

    FIREARM TRANSFERS

    • Firearms must ship to a licensed FFL dealer of your choosing — confirm with them first that they can accept the transfer.
    • Your receiving FFL will need to email their license to [email protected] before we can ship.
    • Inspect your firearm at your FFL’s location before signing ATF Form 4473 — once signed, the firearm is considered accepted.

    You’re responsible for knowing the firearms laws in your state before ordering. For complete shipping, returns, and restocking-fee policy details, see our Shipping & Returns page.
