Cosmetic Blemish Sons Of Liberty Gun Works Lower Receiver
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.

Prefect pressure fit with the upper, no wiggle at all. Blem was a small scuff on bottom of the magwell which exposed some metal, likely going to happen with regular use anyway, touch up with some cold blueing and its completely unnoticeable.

I couldn’t find the “blem”. My builder tested it and all specs were perfect. Why pay more when you don’t need to, buy blems and rattle can
