These lowers come engraved with FIRE / SAFE on both sides of the receiver. This Cerro-forged 80 percent lower is not an FFL item; classified by the ATF as a non-firearm. It's made from T6 heat-treated 7075 aluminum with a Type III hardcoat anodized finish to protect against wear and tear and corrosion. Its magwells have been flared and broached, and all it needs is a machined trigger and safety well in order to be a fully functional, mil-spec lower receiver. Review some of the graphics that can be engraved by clicking on the Magwell and Safety tabs above, and customize the look of your 80 percent lower.
