OPF-G, EFLX / DPP is compatible with Glocks that use Glock's Set 01 plates (17, 19, 22, 23, 26, 34, 45, and 47). G40 (10mm) uses Set 02 plates that are slightly wider, while OPF-G, DPP/ EFLX still works with it, it will not completely fill the MOS cut's width.
OPF-G, EFLX is compatible with the Leupold's Delta Point Pro and the EOtech EFLX Red Dot Sight . DPP sight to plates are longer, while EFLX uses shorter screws.
Note that OPF-G, EFLX comes with plate to slide mounting screws, but not the sight to plate screws that will with EFLX sight.
OPF-G, EFLX uses the same proven design of the OPF-G, RMR to keep the EFLX immobile, the simplest and most effective way to prevent sight to plate mounting screws from loosening and shearing.
While EFLX 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, EFLX has a front and rear fence, the tight tolerances of the plate to slide, and sight to plate ensures minimum movement along the bore in recoil.
OPF-G, EFLX ships with 2 plate to slide screws (M3 0.5mm x 6mm), a T10 wrench, and a packet of VC-3. 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: 20 to 25 in/lb
Note that OPF-G, EFLX comes with plate to slide mounting screws, but not the sight to plate screws that will with EFLX sight.
