Scalarworks SYNC/03 RMR Red Dot Mount – Fits Mossberg 500/590/930

The Scalarworks SYNC/03 is the ultimate low-profile red dot mount for Mossberg shotguns, delivering unmatched strength-to-weight performance for tactical and competition setups. Compatible with the Mossberg 500 Tactical, 590/590A1, and 930 series shotguns, this mount is precision CNC-machined from 7075-T6 billet aluminum—the same material used in aerospace and military applications for its superior strength and durability.
