OPF-S, RMR (Optics Platform, Staccato, RMR) is designed for optics ready Staccato P, C, C2 and XC with the factory or aftermarket 0.285 front sight. OPF-S, RMR features a dovetail compatible with the steel rear sight we designed and make for OPF-S, RMR and OPF-S, ACRO.
Precision milled from a solid block of 4140 and nitride coated, OPF-S, RMR is a solid state plate sans moving parts. We have taken steps to make the plate as light as possible, there is a rather significant lightening cut on the plate, which necessitates the use of a sealer plate for Trijicon RMR.
