ZEV Technologies MEGA Forged Upper Receiver

The ZEV Technologies MEGA Forged Upper Receiver is a precision-machined component engineered for AR-15 builds demanding tight tolerances and mil-spec compatibility. Built from 7075 T6 aluminum forgings, this stripped upper receiver is machined to ±.001" tolerances, ensuring reliable function with both factory mil-spec and aftermarket parts and accessories. For operators and builders prioritizing accuracy and repeatability, this upper receiver provides the foundation for a duty-grade or match-grade AR platform.

The MEGA designation reflects ZEV's commitment to dimensional precision and material quality. 7075 T6 aluminum is a high-strength aerospace alloy selected for its superior fatigue resistance and rigidity compared to standard 6061 T6 forgings. The tight tolerances mean bolt carrier groups cycle consistently without binding, reducing wear and extending component life. Because this receiver arrives stripped, builders retain complete control over configuration—barrel profile, gas system length, bolt carrier type, charging handle style, and handguard selection can be optimized for the specific mission or application.

This upper receiver appeals to precision riflemen assembling match-grade builds, law enforcement armorer s customizing duty rifles, and serious sport shooters who require dimensional consistency. The forged construction and mil-spec alignment also make it suitable for builders integrating legacy or contemporary optics mounts, rail systems, and accessory platforms without fitment complications. At 0.65 lbs, the receiver contributes minimally to overall weapon weight while maintaining the structural integrity expected in demanding patrol, range training, or precision shooting applications.
