The ZEV Technologies Forged AR-15 Stripped Lower Receiver (part no. LR-556-FOR) starts as a 7075-T651 aluminum forging that ZEV machines to tolerances tighter than standard mil-spec, giving builders maximum compatibility with mil-spec and aftermarket parts. ZEV finishes the receiver in a True Black Class 2 Type 3 hard-coat anodize and adds its distinctive Gator Grip texture to the front of the magazine well strap for extra purchase during reloads. Between the tight tolerances and the premium finish, this is a lower built for shooters who want a demonstrably better base than a standard forging before they even start their build.
