Zev Forged Upper 556nato Blk

The ZEV Forged Upper Receiver in 5.56 NATO Black is a precision-machined AR-15 upper receiver purpose-built for shooters who demand uncompromising dimensional accuracy and component compatibility. Manufactured from 7075-T6 aluminum forgings, this stripped upper is machined to tolerances of ±.001 inches—better than MIL-SPEC standards—ensuring flawless fitment with both mil-spec and premium aftermarket lower receivers, handguards, and rail systems.

The 7075-T6 aluminum alloy delivers superior strength-to-weight characteristics compared to standard 6061 aluminum, critical for upper receivers that must withstand repeated firing cycles and accessory mounting loads without deflection. At 0.69 lbs, this stripped upper is lightweight enough for extended patrol or training use while maintaining the structural rigidity necessary for sub-MOA accuracy platforms. The black anodized finish provides corrosion resistance in field environments and matches standard mil-spec AR-15 aesthetics.

This receiver is ideal for operators and precision shooters building a custom 5.56 NATO rifle without compromises. Whether configuring a designated marksman rifle, carbine, or specialized platform, the forged construction and tight machining tolerances eliminate receiver-induced accuracy variables. Stripped uppers allow complete control over bolt carrier group selection, charging handle, optics mounting systems, and barrel profile—essential for those optimizing builds for specific missions or competition disciplines.

ZEV Technologies positions the forged upper receiver as a foundation component for serious builds, prioritizing precision manufacturing over rapid assembly. The ±.001 inch tolerance specification is meaningfully tighter than standard MIL-SPEC requirements and ensures this receiver will function reliably across generations of compatible parts without the binding or feeding issues sometimes encountered with looser tolerances.
