Springfield Armory’s Agency Optic System (AOS) Mounting Plate is purpose-built for the 1911 DS, developed in partnership with Agency Arms. Machined from billet steel and finished in black, this plate provides the correct optic height for a natural sight picture and enables quick target acquisition. It features an integral rear sight with a serrated black notch installed on the rear dovetail.
Engineered to work with the Holosun 509T red dot sight, the mounting plate delivers dependable, repeatable performance whether you’re competing or relying on your pistol for defense. The plate comes with mounting screws for installation on the 1911 DS and works in harmony with the Prodigy’s precision-engineered design. Its low-profile design maintains a sleek appearance while delivering the optimal sight height that modern optic-ready 1911 pistols demand.
