C&H Precision FN 509®, FN 510®, FN545® V4 MIL/LEO Plate For Leupold Delta Point Pro / EOTech Eflx FN509-DPP/EFLX

The C & H Precision FN 509®, FN 510®, FN545® V4 MIL/LEO Plate is a duty-grade adapter designed to mount Leupold DeltaPoint Pro or EOTech EFLX reflex sights onto optics-ready FN large-frame pistols. CNC-machined from lightweight 6061-T6 aluminum and protected by a MIL-SPEC Type III hard anodized black finish, it offers far superior structural strength compared to standard factory options. The adapter integrates C & H's patented 416 stainless steel T-posts, providing deep thread engagement to eliminate the risk of sheared screws under heavy recoil. Its low-profile design sits snugly within the factory slide cut, lowering the optic's height over bore to preserve intuitive target acquisition. Proudly made in the USA, this rugged plate provides a secure, movement-free interface trusted by law enforcement and competition shooters alike.
