Arisaka Zero Rtn Clmp Vrts W/sig Std

The Arisaka Zero Retention Clamp Vertical with SIG Standard mounting interface is a precision-engineered handguard accessory mount designed to eliminate zero shift on optics and iron sights installed on the MCX Virtus and Spear LT platforms. Built on patent-pending technology, this clamp solves a critical problem that tactical shooters and military personnel face: maintaining consistent sight picture across high-recoil rifles in field conditions. Whether you're running a canted laser, mounted reflex sight, or backup iron sights, retention and repeatability demand a rock-solid mechanical interface.

The Zero Retention Clamp achieves superior zero stability through mechanical clamping geometry that locks accessories to the handguard with zero flex and zero creep. Unlike loose picatinny or M-LOK attachments that can shift under recoil, this design constrains all three axes of motion, preventing the micro-movements that accumulate into point-of-aim drift over extended fire missions. Weighing just 0.06 lbs, the clamp adds negligible mass while providing the rigidity demanded in patrol rifles, duty weapons, and DMR builds. The SIG Standard interface matches the MCX Virtus and Spear LT handguard geometry, ensuring seamless fitment without modifications or secondary adapters.

This clamp is essential for operators who need absolute confidence in accessory retention during rapid firing, tactical movement, or sustained engagement. Law enforcement and military end-users benefit most from the guaranteed zero hold—especially those running dual-optical setups (canted secondary laser with primary optic) where any shift cascades into shot degradation. The vertical-mount orientation makes it ideal for handguard-top installations where space and sight-line clearance are critical. Compatible with MCX Virtus builds in 5.56, 300 Blackout, and Spear LT platforms chambered in 5.56, 7.62x39, and 300 Blackout, this Arisaka Defense component is the definitive solution for handguard-mounted accessory zero stability.
