Scalarworks SYNC/04 | Remington 870/1100

The Scalarworks SYNC/04 (SW1400) is a lightweight optic mounting solution designed for Remington 870, 1100, and 11-87 shotguns with the original four-hole receiver pattern. Engineered to accept optics with the Trijicon RMR footprint, this mount provides a streamlined platform for popular red dot sights used in tactical, hunting, and competition applications. Its compact design positions the optic low on the receiver for a consistent sight picture and practical co-witness configuration.

Manufactured in the United States, the SYNC/04 mount is CNC-machined from 7075-T6 aluminum and paired with 4140H steel hardware for durability. A sealed mounting interface helps protect against moisture intrusion, eliminating the need for an additional sealing plate. The mount is compatible with a wide range of Trijicon and Holosun reflex sights, making it a versatile upgrade for Remington shotgun owners looking to add a red dot optic.
