This BCG is made to Mil-Spec standards for upper compatibility and the bolt is made to work with SAAMI spec chambered barrels. Due to the variability of tolerances between manufacturers, specific fit to a barrel or upper is not guaranteed so we recommend checking headspace and fitment on any new build.
