ZEV Forged Black AR-15 Stripped Lower Receiver ZEV Technologies' forged AR-15 lower comes stripped and ready for your build, machined from a 7075 forging to better-than-Mil-Spec tolerances. Why Buy It Forged 7075-T651 aluminum, made in the USA Machined to about .001" tolerances Original ZEV Gator Grip texture on the mag well Flared magazine well for faster reloads Nylon-tipped tension screw for a tight upper fit Overview ZEV final-machines American-made 7075 forgings to better-than-Mil-Spec dimensions, held to roughly .001", so Mil-Spec and aftermarket parts fit the way they should. The receiver is finished in True Black Class 2 Type 3 hard coat anodize. Details set it apart from a plain forging: the Gator Grip texture on the front of the mag well gives your support hand purchase, the generous flare speeds reloads, and a nylon-tipped tension screw takes up slop with different uppers. ZEV does not ship it to Washington or Illinois. It is a premium start to a custom AR, available at BattleHawk Armory.
