Frequently Asked Questions

What are the basic steps to install an optic on a Glock MOS pistol?

First, remove the factory cover plate screws. Then, select the correct adapter plate for your optic and place it on the slide. Secure the plate with Glock's shorter screws, mount the optic, and carefully start its mounting screws, avoiding stripping.

What tools are needed to install an optic on a Glock MOS?

You will need a star-head screwdriver to remove the cover plate screws. Glock provides the necessary adapter plates and mounting screws, which often have pre-applied Loctite. Ensure you have the optic and its specific mounting screws.

What is the most critical step when mounting a red dot sight on a Glock MOS?

The most critical step is carefully starting the fine-threaded machine screws that attach the optic to the adapter plate. Extreme caution is needed to avoid stripping these threads, which can cause significant problems.

Can I use the same adapter plate for different red dot sights on my Glock MOS?

No, Glock provides multiple adapter plates, and you must select the specific plate designed for your particular red dot optic model (e.g., a specific plate for Burris FastFire, another for Leupold DeltaPoint). Using the wrong plate will prevent proper mounting.
