A steel optic plate that mounts a Leupold DeltaPoint Pro on Glock MOS slides, with front and rear fences that hold the sight still under recoil.
The OPF-G, DPP uses the same design as the OPF-G, RMR: a front and a rear fence and tight plate-to-slide and sight-to-plate tolerances keep the sight from moving along the bore in recoil, which is what loosens and shears sight screws. It is a collaboration between TangoDown and Forward Controls Design.
Key features
-
Front and rear fences — Hold the DeltaPoint Pro immobile so the mounting screws are not loaded in recoil.
-
Billet 4140 steel — Machined from billet 4140, heat treated and black nitride coated.
-
Also fits other sights — Works with the Vortex Defender ST, XT and XL and the EOTech EFLX as well as the DeltaPoint Pro.
Compatibility and fitment
- Fits standard Glock MOS slides only. It does not fit the law-enforcement-only MOS3 (DPP), MOS5 (RMR), MOS6 (Holosun 509T) or MOS7 (ACRO) slides.
- It is not an adapter that converts an RMR footprint to a DeltaPoint Pro footprint.
- Slides: Glock MOS G17, G19, G20, G21, G22, G23, G26, G34, G40, G45, G47 and G49. The G40 uses the slightly wider Set 02 plates; the OPF-G, DPP works on it but does not completely fill the width of the MOS cut.
- Sights: Leupold DeltaPoint Pro, Vortex Defender ST, XT and XL, and EOTech EFLX.
- Sight-to-plate screws are not included — use the screws supplied with the sight. With an EOTech EFLX use only the EFLX's own screws: the longer DeltaPoint Pro screws can bend or break the plate.
- Vortex Defender: the sight comes with 11 mm and 9.8 mm M4 screws. Some 9.8 mm screws measure 9.87 mm and will protrude under the plate and bend it during installation — check screw length before use.
- Do not use with the Holosun SCS320; it will damage the plate. Not compatible with the SIG Romeo-X Pro (its lug holes are too shallow).
- Backup sights: the DeltaPoint Pro sits tall and needs equally tall sights for a lower 1/3 co-witness; the Ameriglo GL-808 set gives a lower 1/3 co-witness.
- A torque wrench graduated in in·lb is needed to tighten the screws to the stated values.
