Kastle Group RMR-45™ 45 Degree Offset Red Dot Mount

The Kastle Group RMR-45™ is a low-profile 45-degree offset optic mount designed to integrate Trijicon RMR footprint optics onto modern rifle platforms. Built for shooters who require a fast transition between a primary optic and a secondary red dot sight, the RMR-45™ provides an intuitive backup aiming solution without adding unnecessary bulk or complexity to the weapon system.

Designed for use with Kastle Group’s FORTRESS™ optic mounting ecosystem, the RMR-45™ allows users to mount a miniature red dot directly to compatible Kastle scope mounts, providing a clean and streamlined solution for close-range engagements, passive aiming with night vision, and rapid target transitions.

Machined from premium materials and engineered for duty-grade reliability, the RMR-45™ maintains a rigid connection between the optic and host platform while keeping weight to a minimum. The 45-degree orientation allows the shooter to simply rotate the rifle to access the offset optic while maintaining their primary optic setup.

For night vision users, an offset RMR can provide an extremely effective passive aiming solution when paired with helmet-mounted night vision goggles. The elevated heads-up shooting position reduces the need for awkward head placement and allows for fast, repeatable presentations in low-light environments.
