C&H Precision Weapons Fnx 45 Adap Rmr/Sro/Holo
The C&H Precision Weapons adapter plate for FNX 45 lets you mount modern red dots on your optic-ready FN handgun without gunsmith work. If you're running an RMR, SRO, Holosun 407C, 507C, 508C, 508T, or 507 Comp—or C&H's own EDC-XL or COMP plates—this precision-machined adapter bridges the gap between your FNX frame and your preferred optic footprint. It's a clean, reliable solution for shooters who want to upgrade their duty gun or carry gun with combat-proven glass.
C&H machines every plate on HAAS CNC equipment in their coastal Georgia shop, then runs each one through multiple quality checks. That's not marketing fluff—it means tight tolerances and zero wobble where it matters. The body is 6061 aluminum, durable and lightweight, paired with stainless steel hardware that won't corrode or seize.
Whether you're setting up a nightstand gun, a range toy, or a serious carry piece, this adapter gives you the optics flexibility that FNX shooters have been asking for. No permanent modifications, no fitting headaches—just drop it on and zero your dot.
