Arisaka Defense MCX Zero Retention Clamp, Fits Sig Sauer MCX, Standard Handguard, Anodized Finish, Black ZRC-V-300-SLIM

Overview

The Arisaka Defense MCX Zero Retention Clamp (ZRC) is an aluminum accessory designed to reduce zero shift for lasers and iron sights mounted on the handguards of Sig Sauer MCX Virtus and Spear LT rifles. By utilizing a U-bracket that engages the extended upper receiver underneath the handguard, the ZRC secures the assembly tightly across two axes without contacting the barrel or gas system, thereby preserving the free-float characteristics of the barrel. CNC-machined from 6061-T651 aluminum with a black Mil-A-8625 Type III hard coat anodized finish, the clamp is contoured to minimize interference with the user's grip. This model is compatible with the MCX standard handguard.
