Arisaka Defense Zero Retention Clamp for Spear LT and MCX Virtus - Part ZRC-SPEAR-LT

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

The Arisaka Defense Zero Retention Clamp (ZRC) for Spear LT and MCX Virtus enhances shooting accuracy by significantly reducing zero shift caused by handguard flex. Designed specifically for MCX Virtus models chambered in 5.56 and 300 Blackout, as well as Spear LT variants in 5.56, 7.62x39, and 300 Blackout, this clamp system ensures your sight or laser maintains its zero under various operational conditions. The ZRC is particularly effective in addressing issues stemming from the handguard's inadequate attachment to the upper receiver, which can lead to movement and zero inconsistencies when pressure is applied during shooting. This product is not compatible with the Rattler platform. The innovative design features exterior clamps that thread into a specialized U-bracket, which engages the extended upper receiver underneath the handguard, providing a secure connection across two axes without contacting the barrel or gas system. This preserves the free-floating barrel design while stabilizing the handguard, leading to improved shot consistency. The clamps are contoured to minimize interference with the user’s grip, ensuring comfortable handling during operation. Installation is straightforward, and the clamp system offers a reliable solution for shooters demanding precision and repeatability from their firearm's zero. Constructed with durable materials, the ZRC is built to withstand rigorous use while maintaining its secure fit and effectiveness over time. Whether you're engaging in tactical scenarios or precision shooting, this clamp system helps ensure your sight alignment remains consistent, reducing the need for frequent zero adjustments and enhancing overall shooting confidence.
