    Receiver Extension Nut

    When I needed to replace my carbine's receiver extension nut BCM was the first company to come to mind. Installation was simple with a perfect fit. This nut torqued up to 40 ft/lbs without any problem or deformation.

    Support BCM

    I don’t even have an AR but I needed a castle nut for an Ak stock. The quality is second to none but the main reason I went with BCM is because they sponsor the Bongino podcast, which I also recommend
