Product description

The Aimpoint® COA™ R sight model is developed for rifle use and hunting, with a focus on longer shooting distances and varied field scenarios. While retaining the COA platform’s low weight, tubeless construction, and ability to support fast target acquisition, COA R is configured specifically for tempo, precision, and quick follow-up shots in dynamic hunting situations. It offers a compact optical solution for hunters seeking a clear, unobstructed view and rapid engagement capability on rifle platforms.

To ensure mounting versatility, COA R uses a dedicated mount plate that converts the A-CUT™ footprint into a MICRO® compatible interface (#PA000700 – sold separately and required for all MICRO mounting solutions). This means that using AIMPOINT MICRO mounts is only possible when this mount plate is installed. It enables compatibility with existing MICRO mounting solutions while maintaining the mechanically locked system that secures the optic without screws entering the housing. The result is a stable, repeatable attachment that delivers confidence for accurate shooting at extended ranges.

For hunters seeking the COA platform’s speed and clarity on a rifle, the Aimpoint® COA™ R offers a compact, and precise red dot sight.
