Forward Controls Design OPF Optics Platform For Sig Sauer P320 – Trijicon RMR

Machined in 4140 steel and Melonite coated, OPF-P320, RMR, is a new member of their OPF (Optics Platform, Forward Controls) line.  They again eschew aluminum for this application, and continue to use steel as other OPF plates, they prefer steel plates for steel screws.  4140 steel costs more and takes longer to machine, they use it extensively on other products.  They 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.

Proudly designed and made in USA.

Incompatible: M17/M18, and SIG P320 with integrated optics plate and rear sight

Please NOTE:

• OPF-P320, RMR, was designed and made for Trijicon's RMR, though Holosun 507c, 508T and 509T (with the adapter plate it comes with) also work on it, they do not guarantee fit and function for these sights.
• OPF-P320, RMR will not work on either commercial or mil issued M17 and M18, and P320s whose rear sight and optics plate are integrated.  It will only work on P320 with slides with separate plate and rear sight.
• Incompatible: M17/M18, and SIG P320 with integrated optics plate and rear sight
