No compromises are made as every crucial aspect is meticulously examined and double-checked. While this BCG maintains SOLGW’s impeccable factory standards, it boasts a unique feature that sets it apart from the rest—a beautifully laser-etched Lone Star logo on the carrier.

SOLGW takes pride in being completely transparent, and we provide you with a comprehensive breakdown of the BCG below.

SOLGW Lone Star Lower
Description
In a joint project with our friends over at Rogue American Apparel we bring you LONE STAR.
Lone star was our second lower ever released all the way back in 2015. We have re-released it for 2018 and plan to make it a stocking item. Represent your fierce Texas Pride with LONE STAR.
Head over to Rogue American’s site and check out the other equally awesome gear.
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.
