Red dot mounts for Mossberg

A red dot sight on a Mossberg firearm gives you a single aiming reference that's faster to acquire than open sights, particularly under time pressure. Whether fitted to the rear sight dovetail of an MC1 or MC2 pistol, or to the receiver of a 500, 590, or 930 shotgun, the optic attaches without permanent modification to the frame or receiver.

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.

The dovetail specification and slide dimensions vary between Mossberg models and generations — always check the individual product page to confirm the mount fits your specific pistol before ordering.
