Firefield RA-45 Modular 45 Degree Offset RDS Mount

Description

The Firefield RA-45 Modular 45 Degree Offset RDS Mount provides a versatile solution for mounting a micro red dot sight alongside a primary riflescope. Its 45-degree offset positions the secondary optic for rapid transition between magnified and unmagnified aiming, while the reversible design supports both left and right-side mounting.

Firefield centres the RA-45 around the bore axis to promote fast, intuitive red dot acquisition when the rifle is rotated. The 1.75-inch offset keeps the optic close to the rifle while providing sufficient clearance around most scope turrets, resulting in a compact and efficient dual-optic configuration.

Firefield RA-45 Modular 45 Degree Offset RDS Mount Features

• 45-Degree Offset Mount: Positions a micro reflex sight at a 45-degree angle, allowing rapid transitions from a magnified scope to a close-range red dot sight.
• Modular Plate Design: Three interchangeable mounting plates support popular micro red dot footprints, therefore one mount can accommodate a broad selection of optics.
• Docter/Venom Compatibility: Plate 1 supports compatible Docter and Venom footprint reflex sights for flexible optic selection.
• RMR Compatibility: Plate 2 provides direct mounting for compatible RMR footprint red dot sights.
• RMSc Compatibility: Plate 3 accommodates compatible RMSc footprint optics, expanding support for compact micro reflex sights.
• Reversible Configuration: The RA-45 can be installed on either side of the rifle, consequently supporting left and right-handed shooting preferences.
• Bore-Axis Alignment: The mount is positioned around the centre axis of the bore, helping the secondary optic move naturally into view when transitioning from the primary scope.
• 1.75-Inch Offset: The calculated offset keeps the red dot close to the rifle while allowing clearance around most riflescope turrets.
• Low-Profile Construction: The compact mount can fit beneath many cantilever scope mounts, providing greater flexibility when arranging optics and accessories.
• 6061-T6 Aluminium: Durable aluminium construction combines strength with low weight, avoiding unnecessary bulk on the rifle.
• Matte Black Finish: The non-reflective surface creates a discreet appearance and complements most black rifle and airsoft configurations.

The Firefield RA-45 includes Docter/Venom, RMR and RMSc mounting plates, enabling direct compatibility with many popular micro reflex sight designs. Two additional plate mounting screws and a T15 Torx wrench are supplied alongside the quick-start guide, so installation and configuration remain straightforward.

For airsoft rifles, DMR builds and other scoped setups, the Firefield RA-45 Modular 45 Degree Offset RDS Mount creates an effective combination of magnified and close-range optics. Since its modular footprint system, reversible orientation and low-profile 45-degree design provide considerable installation flexibility, the RA-45 offers a practical way to add a secondary red dot sight without compromising the primary optic.
