The Sons of Liberty Gun Works AR-15 lower receivers are built from mil-spec 7075-T6 forgings from the lead forge in the U.S. They contour is fully machined leaving no flash marks from the forging. We take extra care when machining our lower receivers resulting in tolerances that are tighter and fits that are better than other lower receivers. We use mil-spec Matte black hard-coat anodized Mil 8625 Type 3 Class 2 finish.
When ordering, please put your dealers BUSINESS NAME in the SHIP TO section and then have them e-mail their license to us.
