Overview

Built for mounting a scope on a rifle with a Picatinny (MIL-STD-1913) rail, these medium-height 40mm rings are aimed at shooters who want a purpose-driven setup rather than a generic accessory. The design is presented as an evolution of ARC’s M10 Scope Rings, with an emphasis on return-to-zero and a fit that can be selected by diameter, height, and inclination. CNC-machined from high-strength 7075 aluminum, they suit hunters and riflemen looking for a straightforward, precision-oriented mounting solution.

Considerations & Trade-offs

  • At $249, these rings sit at a premium price point compared with more basic mounting options.
