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.


  • Forged from 7075-T6 aluminum
  • Machine finished to improve tolerances
  • Matte black hardcoat anodized finish
  • Angry Patriot Logo
  • Three position selector markings
  • Compatible with Mil-Spec parts and receivers
  • B5 Furniture

    SOLGW quality outshines itself. Pairs well with my 13.7 SOLGW upper.

  2. darren.decker712 (verified owner)

    By far my favorite lower I’ve owned. Have had a few different uppers on it and everything has run great. Best “mil spec” trigger I’ve ever experienced. Starting to see why SOLGW has such a cult following.

    Shipped same day, love this lower with my PWS upper.

    Love this lower! Top quality everything! Unmatched warranty! Definitely my favorite manufacturer. If something ever does go wrong, they fix it! Even if you run it over with a truck!

    Lightning fast shipping, fit and finish is perfect .. superb lower. I highly recommend… paired with my 14.5 Bcm upper makes for a sweet shooter.. the A5 buffer and mid length gas system combo is a marriage made in heaven
