C&H Precision FN 509®, FN 510®, FN545® V4 MIL/LEO Plate For Holosun EPS-EPS Carry FN509-EPS

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 enclosed micro reflex sights onto factory optics-ready FN slides. CNC-machined from structural 6061-T6 aluminum with a black MIL-SPEC Type III hard-coat anodized finish, this low-profile plate maintains a slim deck height under 0.10 inches. It transforms the proprietary factory FN slide cut into a form-fitting interface tailored specifically for the Holosun EPS footprint, delivering an exact fit for the Holosun EPS, EPS Carry, and SCS Carry optics. To withstand intense cyclic slide forces and completely prevent hardware failure under heavy recoil, the design incorporates patented 416 stainless steel T-nuts and replaceable T-posts to provide six to seven threads of maximum engagement. Operating entirely without internal electronics or battery power, this American-made hardware package is widely available through tactical components suppliers like Primary Arms and Freedom Gorilla, arriving pre-bundled with a complete stainless steel multi-screw mounting kit backed by a full Lifetime Warranty.
