The C&H Precision Weapons MOS Adapter Plate for Glock bridges the gap between your pistol's factory mounting system and modern red dot optics. If you're running a Glock MOS slide and want to mount a Holosun 507K—one of the most popular compact pistol red dots on the market—this precision adapter gets you there with rock-solid reliability. C&H Precision manufactures these plates in-house at their coastal Georgia shop, holding each to CNC tolerances that matter when your optic is the aiming system on a defensive or competition pistol.

Built from 6061 aluminum with stainless steel hardware, the adapter plate is engineered to be both lightweight and durable. The design is straightforward: it converts your Glock MOS interface to accept the Holosun 507K footprint, preserving the co-witness capability and ergonomic advantages of a slide-mounted optic. Every plate passes multiple quality inspections before shipping, so you know what you're getting is square, properly finished, and ready to mount.

This is purpose-built American-made hardware for shooters who demand precision. Whether you're setting up a carry pistol, competition gun, or duty rig, a quality adapter plate is the foundation of a reliable optics installation. Installation requires a small amount of care and the right fasteners, but the fit and finish from C&H makes the job straightforward.
