Forward Controls Design Milspec M17/M18 Optic Mounting Plate, Rear Sight Dovetail

The Forward Controls Design Milspec M17/M18 Optic Mounting Plate is a precision-machined adapter that brings modern red dot capability to military-issued Sig Sauer M17 and M18 pistols. Built from 4140 steel with QPQ corrosion-resistant coating, this rear sight dovetail mount delivers the accuracy and durability demanded by professional users and serious shooters who need reliable optics on duty or carry guns.

Engineered to mount Aimpoint ACRO P1 and P2 sights with the tight tolerances their optical systems require, this plate has earned trust among professionals specifically because it adheres to Aimpoint's official technical data. The dovetail design maintains the M17/M18 profile while giving you the advantage of a proven optic platform without permanent modifications to your pistol.

Forward Controls Design manufactures this plate in the USA to demanding specs. Installation is straightforward: the kit includes two M4 fasteners (0.7mm x 6mm, torque 20–25 in·lb), a T20 hex key, and loctite to secure your sight. This approach means you can mount and remove your optic as needed, keeping your options open whether you're at the range, in duty rotation, or training.
