Red dot mounts for Beretta M9A3

Adding a red dot to the Beretta M9A3 gives you a single focal plane on the modernised M9 with Vertec grip, front serrations, and suppressor-height sights. The optics-ready rear sight cut on the M9A3 is designed to accept a mounted optic directly.

A dovetail red dot mount fits directly into the rear sight dovetail on your pistol — the same cut that holds the factory rear sight. The mount replaces the rear sight and positions the optic directly above the slide in the sighting plane. Installation requires no gunsmithing and no machining: remove the rear sight, seat the mount in the dovetail, and tighten the setscrew. The modification is fully reversible — if you want to return to iron sights, you reinstall the factory rear sight and the slide is unchanged.

Compatibility depends on the specific model and configuration — always check the individual product page before ordering.
