ZEV Technologies Wedge Lock Hand Guard 16 5/8

The ZEV Technologies Wedge Lock Hand Guard 16 5/8 is a free-floating aluminum rail system engineered for shooters who demand precision accuracy and modularity on modern sporting rifles. Designed for professional and civilian operators running AR-pattern platforms in 5.56 NATO, this hand guard replaces traditional delta-ring attachment systems with an innovative stainless steel barrel nut and proprietary two-piece Wedge Lock mechanism. Built for those who refuse to compromise between performance and ease of installation, the Wedge Lock system tightens completely with a single fastener—eliminating the frustration of traditional multi-screw assemblies while maintaining rock-solid repeatability.

Machined from aircraft-grade aluminum with thick wall construction, the 16 5/8-inch profile delivers a lightweight, rigid platform that minimizes harmonic vibration and supports consistent zero retention shot after shot. The Wedge Lock design uses mechanical geometry rather than friction alone—the wedge shape forces the hand guard into absolute concentricity with the barrel, a critical factor in precision rifle builds where even minor runout degrades accuracy. Weighing just 1.58 pounds, this hand guard integrates seamlessly with standard Picatinny rail sections, allowing unlimited accessory configuration without adding bulk. The included stainless steel barrel nut ensures corrosion resistance and long service life in demanding field conditions.

Law enforcement precision rifle teams, competitive shooters, and military-adjacent professionals benefit most from ZEV's engineering—the Wedge Lock hand guard eliminates the POI shift that occurs when hand guards loosen over time. Installation is straightforward: secure the stainless steel barrel nut to the receiver, position the two-piece wedge system, and tighten the single retention screw to specification. The 16 5/8-inch length provides ample real estate for optic mounts, lights, and fore-end accessories while maintaining a compact profile suitable for CQB and mid-range engagement scenarios. This hand guard is compatible with all standard AR-15 upper receivers and 5.56 NATO platforms.
