OPF-G, RMR is compatible with RMR, SRO, and the new RMR HD and RCR.  If you have an RCR, you must use the capstan screws that came with the RCR.

If your RMR HD came with screws, do not use the 6-32 x 1/2 screws that came with RMH HD, please use the 6-32×3/8 screws, or our 6-32×3/8 T15 screws we provide.

Do not use our sight to plate screws with Holosun sights.  The screws we supply are for Trijicon RMR and SRO only.  From October of 2023, we’ve begun to transition T10 sight to plate screws to T15.

OPF-G, RMR is designed for GLOCK’s MOS and Trijicon RMR and SRO.  If you use a Holosun and the long set of screws with OPF-G, RMR, you will risk damaging the plate.  Holosun sights have 90 degree countersink screw holes, while RMR and SRO use 82 degree countersink.  In addition, the supplied RMR sight to plate screws (6-32 x 3/8) are longer than what Holosun includes.  Do not use our sight to plate screws with Holosun sights.

Our plates are made in ordnance grade 4140 steel, but it’s not immune to user induced abuse.  This can happen if the wrong Holosun screws are used with our plate.
