Based on Forward Controls Design successful Glock MOS compatible plate design, OPF-PDP, RMR is made for the Walther PDP and Trijicon RMR.
Featuring the same tight tolerances and design that hold the sight immobile on the plate, OPF-PDP, RMR was created to satisfy LE and defensive carry users demand for an RMR plate that FCD created for Glock MOS. FCD did have some reservations, as they only choose to take on projects where they can truly bring improvement to the platform, it is not Forward Controls goal to create a plate for every pistol that can accept one, nor every optic that exists for it.
For the Walther PDP, FCD came across challenges they didn't encounter with the Glock MOS, namely, the PDP optics cut lacks an anti-shift, anti-rotation mechanism found on the Glock MOS. The plate can't move along the bore much due to its being enclosed in the pocket, but it is possible to rotate it, and shift it laterally before the screws are installed.
OPF-PDP, RMR is machined with the same attention to detail and tight tolerances as other plates in the OPF family of products, this now comes into play as a factor for mitigating rotation of the plate in the PDP's optics cut. The tight tolerance of the plate means it can't be easily rotated before the plate to slide screws are installed. This is crucial, as the small plate to slide screws aren't recoil lugs, and perform poorly as such, it'd be wishful thinking to believe the screws can perform anti-rotation, anti-shift functions on their own.
Machined from solid 1018 steel and black nitride treated. As with any and all OPF line of optics plates, OPF-PDP, RMR is a solid state design with no moving parts.
Proudly designed in Texas, and made in ID, USA.
