Springfield Armory 1911 DS Prodigy AOS RMR Optic Plate Kit - SKU: PH5077N-RMR-PLATE-SET - UPC: 706397961367
Product Description
The Springfield Armory PH5077N-RMR-PLATE-SET is a factory Agency Optic System (AOS) mounting plate engineered specifically for the 1911 DS Prodigy series of handguns. Developed in collaboration with Agency Arms, this steel optic plate adapts the slide's specialized AOS footprint to accept red dot sights utilizing the industry-standard Trijicon RMR footprint—including the Trijicon RMR/SRO and Holosun 407C/507C/508T optics.
Precision-machined from high-strength billet steel and finished with a durable black Melonite/nitride treatment, this plate ensures maximum shear strength against reciprocating slide velocity. The unit features an integrated rear iron sight machined directly into the plate body. When paired with the factory tall front sight of the 1911 DS Prodigy, it provides an immediate co-witness sight picture for seamless backup indexing in the event of optic battery or emitter failure.
The system utilizes deep indexing recoil bosses and custom mounting screws to distribute shear forces away from the optic fasteners, preserving zero retention and preventing screw shearing under high-volume firing schedules.
