Overview

Built for mounting a scope on a Picatinny rail, these rings are aimed at hunters and riflemen who want a secure, repeatable setup rather than a quick, casual solution. The 40mm high configuration gives you a specific fit option within the M-BRACE line, which is offered in different diameters, heights, and inclinations to match a range of rifles and optics. CNC-machined from high-strength 7075 aluminum, they reflect a more deliberate approach to scope mounting, with return-to-zero performance called out as a key feature. For shooters who value a straightforward, purpose-built interface between optic and rifle, this is a premium mounting option with a no-frills focus.
