Arisaka Zero Rtn Clmp Spear 7.62 Std

The Arisaka Zero Retention Clamp Spear 7.62 Standard is a patent-pending optical mounting solution engineered to eliminate zero shift on precision rifles where handguard-mounted lasers and iron sights demand rock-solid stability. Developed for serious operators—law enforcement tactical teams, military marksmen, and professional shooters—this clamp addresses a critical problem: traditional mounting methods allow micro-movement under recoil, causing point-of-aim drift that compromises accuracy and target engagement speed. The Spear 7.62 variant is purpose-built for modern intermediate and full-power platforms operating in high-stress environments.

The Zero Retention Clamp uses a precision mechanical design that locks optics and sighting devices directly to the handguard with zero tolerance for movement, preventing the creep and vibration that degrades shot placement. Its intelligent clamping geometry distributes pressure evenly across mounting surfaces, eliminating stress concentration that can damage delicate optic tubes or shift optic zero over time. The lightweight design—just 0.19 lbs—adds negligible weight while maintaining the rigidity required for repeated firing cycles and rapid target transitions. Material construction and finish are optimized for field durability, corrosion resistance, and compatibility with modern weapon platforms operating in diverse climates.

This clamp is specifically engineered for the MCX Virtus platform in 5.56 NATO and .300 Blackout, as well as the Spear LT in 5.56 NATO, 7.62x39, and .300 Blackout—configurations favored by tactical operators requiring versatile intermediate caliber performance. Installation is straightforward for gunsmiths and field-tested shooters, requiring no permanent modifications to the host rifle. Whether outfitting a duty weapon, precision rifle, or specialized platform, the Arisaka Zero Retention Clamp Spear 7.62 Standard delivers the zero stability and confidence required in critical situations where accuracy cannot fail.
