The Springfield Armory Micro AOS Mounting Plate A12B for 1911 DS pistols is designed for mounting compact micro red dot sights onto Springfields Agency Optic System (AOS)-equipped double-stack 1911 models. Built for precision, versatility, and durability, the A12B plate is ideal for enhancing concealability and target acquisition on slim-profile optics.
This A12B mounting plate supports a wide range of micro reflex sights designed for concealed carry and low-profile use. The plate integrates directly into the 1911 DS AOS cut, allowing secure attachment with the optic manufacturer’s screws. While some optics may require screw modification, most are drop-in compatible. The Micro AOS design maintains sight alignment, enhances co-witnessing potential, and provides a robust interface for reliable optic retention and zero maintenance.
