Cross Armory Crrmadapter Adapter Plate Oxide Alumn Compatible W/ Rmr Optics

The Cross Armory RMR adapter plate bridges the gap between your pistol slide and Trijicon RMR optics. If you're running a red dot sight on a carry gun, duty weapon, or competition pistol, this black oxide aluminum mounting solution handles the job with minimal footprint. The adapter plate is engineered to securely mate RMR-pattern optics to slides that don't have direct RMR cuts, giving you a clean, repeatable zero without gunsmithing or permanent modifications.

Built from black oxide aluminum, the plate resists corrosion and maintains a low-profile footprint on your slide. Whether you're setting up a primary carry gun, a backup optic configuration, or experimenting with different pistol-mounted red dots, this adapter lets you standardize on RMR compatibility and swap between platforms without losing zero. The black oxide finish blends seamlessly with modern pistol aesthetics and holds up to the wear of daily handling and range use.

Cross Armory focuses on practical, no-nonsense mounting solutions for shooters who want their optics to stay put. This adapter plate reflects that philosophy—straightforward functionality, solid construction, and the kind of accessory that disappears into your setup once it's installed and verified at the range.
