Product Info for American Rifle Company M-Brace 40mm Riflescope Mount

The M-Brace Scope Mount is engineered from the ground up to provide the most secure, recoil-proof mounting system for high-precision optics. Designed for shooters who demand uncompromising strength, precision, and reliability, the M-Brace Scope Mount ensures rock-solid alignmenteven under the harshest recoil forces. The M-Brace Scope Mount is built with an advanced serrated interface, inspired by Hirth couplings used in high-power gas turbines and machine tools. These serrations provide an unrivaled mechanical lock between the scope mount and accessories like laser range finders, ensuring that alignment remains rock-solideven under extreme recoil forces exceeding 200 lbs (900N). Unlike competing designs that concentrate stress in a single ring cap or an asymmetric mount, the M-Brace distributes forces evenly and efficiently into the rifle receiver, preserving both your optic and your zero.image
