Glock MOS Adapter plate 02 for Trijicon, Holosun (except 509), Ameriglo

The GLOCK MOS Adapter Plate 02 is a factory adapter plate that lets you mount compatible red dot sights into a GLOCK slide prepared for the MOS (Modular Optic System) configuration. Plate 02 is intended for use with popular footprint patterns including Trijicon, Holosun (except model 509), and Ameriglo on GLOCK slides with a 25.5 mm slide width. It provides a secure, low-profile interface that preserves the pistol’s slide fit and sight geometry when installing miniature reflex sights.

ABOUT THE MOS ADAPTER PLATES

GLOCK’s MOS adapter plates are part of the Modular Optic System that simplifies mounting of widely used reflex sights. Instead of proprietary machining for each sight, the MOS system uses numbered adapter plates so a variety of red dots can be installed quickly and repeatably. This approach keeps installation straightforward while maintaining alignment and durability for duty, sport, and defensive use.

ABOUT THE MODEL (ADAPTER PLATE 02)

Adapter Plate 02 is designed for GLOCK pistols with the MOS slide cut sized at 25.5 mm and matches the mounting footprints of Trijicon, Holosun (except 509), and Ameriglo optics. If your GLOCK slide has a different width (for example 27.5 mm or 28.5 mm), refer to the corresponding adapter plate numbers for compatibility.
