C&H Precision RMR Plate For Holosun 407K/507K RMR-HOLOK

The C & H Precision RMR Plate for Holosun 407K / 507K is a precision-engineered 1x unmagnified conversion adapter designed to mount compact, slimline reflex sights onto full-sized pistol slides or mounts. CNC-machined from lightweight 6061-T6 aluminum at their Coastal Georgia facility, this low-profile plate features a baseline thickness of just 0.095 to 0.099 inches and is protected by a MIL-SPEC Type III hard-coat black anodized finish. It converts a standard, full-sized Trijicon RMR footprint into a secure interface that accepts the Holosun K-series sub-compact footprint—including the Holosun 407K, 507K, EPS, and EPS Carry models—while actively preventing raw side overhang. To withstand heavy cyclic recoil forces, the plate utilizes patented 416 stainless steel T-nuts and replaceable T-posts to deliver six to seven threads of maximum engagement. Operating entirely without internal electronics or batteries, this ultra-lightweight adapter weighs approximately 0.45 ounces and comes packaged with stainless steel mounting hardware backed by the C & H Precision Lifetime Warranty against manufacturing flaws.
