Scalarworks SYNC/03 | Mossberg 590/930

The Scalarworks SYNC/03 is a low-profile red dot mount designed for select Mossberg shotguns, including the 590, 590A1, and 930 series. Compatible with optics that use the Trijicon RMR footprint, this mount provides a direct and streamlined way to attach popular reflex sights to your shotgun. Its compact design places the optic close to the bore axis, supporting a natural sight picture and consistent shooting ergonomics.

Manufactured in the United States, the SYNC/03 mount is CNC-machined from 7075-T6 aluminum and finished with Type III black anodizing for durability and corrosion resistance. The mounting interface incorporates an O-ring equipped screw system designed to help seal the optic interface. The mount is compatible with a range of Mossberg tactical shotguns and several widely used reflex sights from Trijicon and Holosun.
