OSA Glock Optic Cut – Trijicon RCR
The OSA Trijicon RCR Optic Cut is designed for shooters who demand the durability of an enclosed-emitter optic without sacrificing the proven RMR footprint. By machining the Trijicon RCR directly into your Glock slide, this service creates a secure, low-profile mounting solution that eliminates the need for adapter plates while maximizing strength and reliability.
Even better, this cut remains compatible with the broader RMR footprint ecosystem, giving you the flexibility to switch optics in the future without having your slide re-machined.

Mounting Hardware
- Trijicon RCR: Uses the factory 6-32 x 3/16" Capstan screws included with the optic.
- Trijicon RMR / RMR HD / SRO: Requires optional 6-32 x .400" mounting screws.
- Holosun 507C / 507 COMP / 407C / 508T: Requires optional 6-32 x .320" mounting screws.
Precision Machining
The slide is machined to a depth of 0.150", allowing the optic to sit significantly lower than adapter plate systems while maintaining maximum strength.
Integrated front indexing posts precisely locate the optic and help absorb recoil forces, reducing stress on the mounting screws and improving long-term durability.
The result is a direct-mount system designed to maintain zero under hard use while providing a clean, factory-like appearance.

Our Thoughts
The Trijicon RCR is quickly becoming one of our favorite enclosed-emitter pistol optics.
It combines the legendary durability of the RMR with the reliability advantages of a fully enclosed emitter, making it an outstanding choice for duty guns, concealed carry pistols, and hard-use range guns.
One of the biggest advantages of this optic cut is future flexibility.
Unlike cuts dedicated to a single optic, the RCR footprint maintains compatibility with several of today's most popular optics, including the RMR, RMR HD, SRO, and Holosun 507C family. If your needs change down the road, you can swap optics without sending your slide back for additional machining.
Every refinished slide also receives a new striker channel liner during reassembly—one of the small details we include to ensure your slide is returned in top working condition.
