Do not use OPF-P320, RMR with Holosun sights, OPF-P320, RMR is incompatible with all known Holosun sights that use the RMR footprint.Trijicon's new RCR and RMR HD are both compatible with OPF-P320, RMR. If you have an RCR, you must use the capstan screws that came with the RCR.OPF-P320, RMR will not work on either commercial or mil issued M17 and M18, and P320s where the rear sight and optics plate are integrated. It will only work on P320s with an independent rear sight.Machined in 4140 steel and Melonite coated, OPF-P320, RMR, is a new member of our OPF (Optics Platform, Forward Controls) line. We again eschew aluminum for this application, and continue to use steel as other OPF plates, we prefer steel plates for steel screws. 4140 steel costs more and takes longer to machine, we use it extensively on other products. We do not deem light weight to be of particular use in this application, but consider reliability and durability far more useful and important qualities.OPF-P320, RMR is a drop in adapter for superb Trijicon RMR sights.OPF-P320, RMR is a Forward Controls Design and Tangodown collaboration.Torque value for T15 6-40 x 9/16 screws: 13 to 15 in lb.RMR will require a sealing plate, while RMR HD, RCR and SRO do not.Proudly designed and made in USA.
