Ruger Mark IV Osight XR Mount

ReaperMount - Lightweight Performance

Engineered specifically for Ruger's legendary Mark series, the ReaperMount delivers lightweight performance with a rock-solid design. Precision-machined from aircraft-grade aluminum, it offers a perfect balance of strength and minimal weight, ensuring your optic stays locked in without adding unnecessary bulk.

Slim. Strong. Secure.

Its low-profile design keeps your red dot close to the bore for faster target acquisition, while the integrated recoil lug provides a stable, repeatable zero—even under heavy use. Compatible with most popular red dot footprints, the ReaperMount is the ideal upgrade for shooters demanding speed, accuracy, and reliability.

Designed and Manufactured in the USA

Our mounts are proudly designed, manufactured, and sold right here in the USA. Each mount begins as a billet of 6061-T6 aluminum and is CNC machined in our Lincoln, Nebraska shop to exacting standards. After machining, we sandblast and finish every mount with H-Series Cerakote—a two part, heat cured ceramic coating that delivers superior scratch resistance while preserving dimensional accuracy. We take pride in supporting American manufacturing and source our raw materials from companies that share the same commitment.
