Arisaka Defense ZRC-SPEAR-LT MCX Zero Retention Clamp for Sig Sauer MCX, LT Standard Handguard, Anodized Finish, Black

The Arisaka Zero Retention Clamp is a patent-pending solution designed to secure handguards on Sig Sauer MCX Virtus and Spear LT rifles, preventing flex that causes shifts in laser or iron sight zero. It fits models chambered in 5.56 and 300BLK, ensuring compatibility without supporting the Rattler variant. By clamping the handguard tightly to the upper receiver across two axes, it eliminates significant zero shifts—up to 5 mils or more—that occur under pressure. This innovative design includes a U-bracket that engages the upper receiver without touching the barrel or gas system, preserving the free-floated barrel for optimal performance. Crafted for durability and ease of use, the clamp minimizes interference with your grip while providing a stable platform for better shooting consistency. Ideal for tactical applications, it ensures your rifle returns to its original zero even after pressure is released from the handguard. Made with high-quality materials in the USA, this accessory offers a reliable upgrade for firearms enthusiasts and professionals alike.
