OPF-G, RMSc is a Glock MOS (not the sub compact MOS G43X and G48 that already have the RMSc footprint), and compatible with RMSc, Vortex Defender CCW, and SIG Romeo X Compact (closed and open emitter) sights.
Due to the wide variety of RMSc compatible sights available, we do not supply the sight to plate screws that are often unique to and ship with the sights, OPF-G, RMSc is shipped with the plate to slide M3 0.5x6mm screws only.
RMSc compatible sights usually ship with different lengths of M4 0.7mm screws. The shorter set of screws are usually the correct length. To confirm the correct length, do not install OPF-G, RMSc on the slide yet, but install the sight on the plate with the shorter screws first, the tip of the screw should not protrude beyond the underside of the plate.
Milled from 4140 steel, and black nitride treated.
Proudly made and designed in the USA.
