Start with Quality Forgings

Meticulous Machining
We wanted perfection, so we teamed up with the folks at DRG Manufacturing Industries. DRG Manufacturing is one of the industries’ best kept secrets. And while we’d love to keep them all for ourselves, we can’t talk about the quality of this lower without giving huge props to their team. Lots of companies are known for their creative vision, others are known for their unwavering attention to detail. DRG does both, and they do it very, very well.
Made in the USA
*Please note that these lowers will have cosmetic blemishes. Functionality is not affected. Blemishes may include bare spots in the engraved logo or “streaks” in the anodizing.
