This guide details the installation of a red dot optic onto a Glock Modular Optic System (MOS) slide, a popular customization for improved target acquisition. The video, presented by Lenny Magill of GlockStore, emphasizes the benefits of red dots for speed and accuracy, especially for shooters with vision impairments. It covers selecting the correct adapter plate for various optic footprints and the proper tools for installation, including a T10 Torx driver. The guide also touches on the necessity of suppressor-height sights for co-witnessing with MOS systems.

Quick Summary

The Glock MOS (Modular Optic System) enables direct mounting of red dot sights using interchangeable adapter plates, eliminating the need for custom slide milling. This system is available for models like the G17, G19, G34, and G41, offering faster target acquisition and improved accuracy, especially for those with vision impairments. Suppressor-height sights are required for co-witnessing.

Frequently Asked Questions

What is the Glock MOS system and how does it work?

The Glock MOS (Modular Optic System) allows users to mount red dot sights directly onto the slide without custom milling. It uses interchangeable adapter plates that fit specific optic footprints, making installation straightforward for compatible Glock models like the G17, G19, and G34.

What are the benefits of using a red dot sight on a Glock pistol?

Red dot sights can significantly improve target acquisition speed by 20-30% and enhance accuracy. They are also beneficial for shooters with vision impairments, as they allow focus on the target rather than the front sight, and are standard in competitive shooting.

Which adapter plates are included with the Glock MOS system?

The Glock MOS system typically includes four adapter plates: Plate 01 for Docter, Insight, and Meopta optics; Plate 02 for Trijicon optics; Plate 03 for C-More optics; and Plate 04 for Leupold DeltaPoint optics.

Do standard iron sights co-witness with optics on a Glock MOS?

No, standard iron sights do not co-witness with optics on the Glock MOS system. You will need to install suppressor-height sights to achieve a usable co-witness, allowing you to use your iron sights if the red dot fails.

What tools are needed to install a red dot sight on a Glock MOS?

The primary tool required is a T10 Torx driver for removing the factory cover plate and installing the adapter plates. A high-quality driver is recommended over the often-included L-wrench for better leverage and to prevent stripping screws.
