    Mil Spec is only same as other but the price is best deal than just add label as BCM, Aero or whatever.

    Finish on the tube was a bit rough, but definitely not lacking. It fit in my luth ar stock and aeryo precision lower like a glove. 5 stars for fit and price.

    It’s getting increasingly difficult to find a standalone A2 buffer tube, and thank god for BKF. Helped me complete my backpack gun for the wild lands. Love these guys.
