Overview
Built for mounting a scope on a rifle setup that calls for a 40mm, 1.50-inch, 45 MOA configuration, this scope mount is aimed at shooters who want a purpose-driven interface rather than a generic accessory. It reflects American Rifle Company’s M-BRACE mounting system, presented as a continuation of the company’s M10 ring design. The provided notes also indicate a possible bolt-handle clearance issue on some actions with 90-degree bolt rotation when mounted in the far aft recoil slot, which may be avoided by shifting the mount forward one slot. Torque specification for the scope clamp is 6.2 Nm, or 55 in-lbs.

Considerations & Trade-offs

- Installation calls for a specific scope clamp torque spec of 6.2 Nm (55 in-lbs), so careful setup is important.
- This is a dedicated scope mounting system, so it is best suited to rifles and rail setups that match the 40mm, 1.50" configuration and 45 MOA design.
- The premium, engineered design and $399 price point make it a more specialized choice than basic scope mounting options.
