C&H Precision FN 509®, FN510®, FN545® V4 MIL/LEO Plate For Trijicon (RMR/SRO/RCR) Holosun (407C/507C/507Comp/508T) C&H (EDCXl/Comp) FN509-RSH

The C & H Precision FN 509, FN 510, and FN 545 V4 MIL/LEO Plate is a premium, 1x unmagnified conversion adapter engineered to securely mount full-sized red dot sights onto factory optics-ready FN handgun slides. CNC-machined from lightweight 6061-T6 aluminum with a black MIL-SPEC Type III hard-coat anodized finish, this low-profile plate measures under 0.10 inches in thickness. It adapts the proprietary slide cut layout into a robust Trijicon RMR footprint, providing native compatibility with duty-grade optics from Trijicon, Holosun, and C & H. To prevent screw stripping under heavy recoil, the design incorporates patented 416 stainless steel T-nuts that deliver an industry-leading six to seven threads of maximum engagement. Operating entirely without batteries or internal electronics, this durable American-made hardware solution arrives pre-bundled with stainless steel mounting screws and features full coverage under the signature C & H Precision Lifetime Warranty.
