OPF-G, DPP (Optics Platform, Forward Controls, Delta Point Pro) is the latest member of the OPF line.  OPF-G, DPP uses the same proven design of the OPF-G, RMR to keep the Delta Point Pro immobile, the simplest and most effective way to prevent sight to plate mounting screws from loosening and shearing.

 

While Leupold's Delta Point Pro uses 4 recoil lugs (twice as that of the RMR's) and beefier mounting screws, the challenges of keeping the sight on the plate without loosening or shearing the sight to plate screws are not very different from those of the RMR.  OPF-G, DPP has a front and rear fence, the tight tolerances of the plate to slide, and sight to plate insures minimum movement along the bore in recoil.

 

 

OPF-G, DPP ships with 2 plate to slide screws (M3 0.5mm x 6mm), 2 Delta Point Pro screws (M4 .7x15.8mm), a T10 and a T15 wrench.  The screws included with the Delta Point Pro are the same screws that ship with the Dela Point Pro, the 2 screws we provide are simply spares.  A torque wrench is necessary to properly install both the plate to slide, and sight to plate screws. 

 

Torque value:

Plate to slide: 13in/lb

Sight to plate: 25in/lb

Due to the DPP's rather tall height, it requires equally tall backup sights for lower 1/3 co-witnessing.  Ameriglo's GL-808 provides lower 1/3 co-witness.l
