OSA Glock Optic Cut – Trijicon RMR HD
Upgrade your Glock with a precision direct-milled optic cut designed specifically for the Trijicon RMR HD. By machining the optic directly into your factory slide, the RMR HD sits significantly lower than factory MOS plates or dovetail adapters, creating a stronger mounting interface, improved durability, and a faster, more natural presentation.
Built for serious duty, concealed carry, and defensive pistols, this direct-mount solution maximizes reliability while taking full advantage of Trijicon's newest flagship pistol optic.
Note: This optic cut is not compatible with the Trijicon RCR or Holosun adapter plates.

Precision Machining
The slide is machined to a depth of 0.150", allowing the optic to sit lower than adapter plate systems while maximizing screw engagement and maintaining a secure mounting interface.
This cut incorporates front indexing posts along with integral recoil bosses surrounding the mounting screws. These precision-machined features absorb recoil forces, reduce stress on the mounting hardware, and help the optic maintain zero even after repeated removal and installation.
The result is a direct-mount system designed for long-term durability and hard use.

Our Thoughts
The Trijicon RMR HD takes everything shooters loved about the original RMR and modernizes it with a larger viewing window, top-loading battery, improved controls, and one of the best automatic brightness systems on the market.
It's quickly becoming one of our top recommendations for shooters looking for a premium duty or concealed carry optic.
A direct-milled installation is the best way to take advantage of everything the RMR HD offers. By eliminating adapter plates, the optic sits lower in the slide, improving presentation, increasing mounting strength, and creating a cleaner overall package.
Combined with precision-machined recoil bosses and quality mounting hardware, this cut provides the durability and repeatability expected from a professional-grade optics system.
Every refinished slide also receives a new striker channel liner during reassembly—one of the many small details we include to ensure your slide is returned ready for years of reliable service.
