The C&H Precision Weapons FN 509/510/545 V4 Adapter EPS is a precision-engineered optic mounting solution designed for shooters running modern FN duty and service pistols with Electronic Aiming Devices (EADs). This adapter bridges the gap between FN's factory slide cuts and compatible enclosed-emitter red dots, enabling rapid-acquisition targeting on proven platforms trusted by law enforcement.
Manufactured using precision CNC machining and hardened steel construction, this V4 generation adapter ensures zero-shift durability across thousands of rounds. The low-profile footprint maintains sight-line geometry and eliminates co-witness conflicts with suppressor-height iron sights. Witness holes allow verification of proper optic seating, while the design accommodates the specific dovetail or direct-mill geometry of FN 509 Compact, 509 Tactical, 510 Tactical, and 545 Tactical variants.
Law enforcement, military support personnel, and civilian defensive shooters benefit most from this adapter's compatibility with the FN 509/510/545 platform ecosystem. The installation is straightforward, requiring no permanent modifications to the slide, making it an ideal choice for both duty use and high-round-count training cycles.
