A steel optic plate that mounts a Trijicon RMR, RMR HD, SRO or RCR on SIG P320 slides that have a separate optic plate and an independent rear sight.
The OPF-P320, RMR is a drop-in adapter machined in 4140 steel and Melonite coated, for P320 slides on which the rear sight sits in its own dovetail and the optic plate can be removed independently. It is a collaboration between Forward Controls Design and TangoDown.
Key features
-
4140 steel — Steel rather than aluminium, Melonite coated.
-
Drop-in fit — Replaces the factory optic plate on compatible P320 slides.
Compatibility and fitment
- Fits only SIG P320 slides with a separate optic plate and an independent rear sight in its own dovetail on the slide.
- Will not work on commercial or military-issued M17 and M18 pistols, or on any P320 whose rear sight and optic plate are integrated.
- If the cut in front of the optic pocket is straight, the plate will not fit.
- Sights: designed and made for the Trijicon RMR; the RMR HD and RCR are also compatible. With the RCR you must use the capstan screws supplied with the RCR.
- Do not use with Holosun sights: the plate is incompatible with all known Holosun sights that use the RMR footprint.
- The RMR requires a sealing plate (not included); the RMR HD, RCR and SRO do not.
- Backup sights: for a lower co-witness, Night Fision offers suitable sights (blade height option 455-440).
- According to Forward Controls Design, the plate can be modified to work with the optics-ready SIG P226 by removing the two tabs at the front underside of the plate.
