C&H Precision V4 LEO/MIL Glock 43X / 48 MOS Optics Plates for Trijicon RMR, Holosun 407C/507C/

Looking to mount a red dot on your Glock without modifying the slide? The C&H Precision GLX-RSH rear sight adapter lets you install popular red dot optics directly into the factory rear sight dovetail — no milling required.

This adapter plate is the perfect solution for Glock owners who want to add a Holosun 507C, 407C, 508T, or Trijicon RMR/SRO to their slide while preserving OEM integrity. It’s ideal for those seeking a backup or non-permanent optic setup — great for concealed carry, range use, or testing a red dot before committing to slide work.

Machined from aerospace-grade materials and finished with a durable hard-coat anodizing, this plate delivers a rock-solid mounting surface while maintaining optimal sight picture alignment. Whether you're training or carrying daily, the GLX-RSH helps bridge the gap between standard Glock slides and modern red dot performance.

🙋 FAQ – Glock Rear Sight Holosun Adapter

Q: Will this adapter fit a Glock without the MOS cut?
A: Yes. This plate is designed to mount optics on Glocks that do not have a MOS cut — it installs directly into the rear sight dovetail.

A: It supports Trijicon RMR, SRO, and Holosun 407C, 507C, and 508T.

Q: Will it co-witness with factory iron sights?
