OPF-G, RMR is compatible with RMR, SRO, and the new RMR HD and RCR. If your RMR, RMR HD, and SRO come with sight to plate 6-32 screws, be sure to only use the 3/8" screws, do not use longer 1/2: screws.

Do not use this sight to plate screws with Holosun sights. The screws we supply are for Trijicon RMR and SRO only. From October of 2023, transition began to 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 this sight to plate screws with Holosun sights.

Plates are made in ordinance 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.
