The C&H Precision Matte FN Pistol Red Dot Adapter Plate is a precision-machined mounting solution that converts FN 509, 510, and 545 optics-ready pistols to accept popular aftermarket red dot sights. If you've got an FN handgun and want to run a quality optic without replacing the gun, this adapter plate bridges that gap—letting you mount Trijicon RMR, SRO, and RCR models, as well as Holosun 507C, 407C, 508C, 508T, and 507 Comp optics, plus C&H Precision's own EDC-XL and COMP plates.

C&H Precision is a small family-owned operation based in Coastal Georgia, and they handle every step in-house: design, CNC machining on HAAS equipment, and quality control. That hands-on approach means tighter tolerances and fewer duds making it to your door. The plate itself is machined from 6061 aluminum and paired with stainless steel mounting hardware, so it'll stand up to hard carry and range work without corroding or wearing prematurely.

This is the kind of accessory that transforms a factory pistol into a practical optics platform. Whether you're setting up for competition, home defense, or just want a more modern sight picture on a solid FN platform, having the right adapter means zero gunsmithing—just bolt-on and go.
