Leupold DeltaPoint Pro Optic Plate for GLOCK Gen 6 by Forward Controls Design
OPF-G6, DPP is a heavy duty Glock Gen 6 ORS compatible plate for Leupold DPP (Delta Point Pro), EOTech EFLX, and Vortex Defender (not CCW) series of sights that use the DPP footprint. It has not been tested on other sights that use the DPP footprint, which can vary, we can only guarantee fit and function on DPP, EFLX and Vortex Defender (not CCW) sights we tested.

For DPP, sights with a front sight height of 0.407" or more are necessary.
For EFLX and Defender, sights with a front sight height of 0.315" work but are very low; 0.350" and 0.385" are recommended.
Glock Gen 6 ORS uses a polymer insert in lieu of an adapter plate. OPF-G6, DPP does not. The elasticity meant to provide upward tension also applies to the lugs on the insert.
Our plates have never used or relied on upward tension to keep the plate-to-slide screws from loosening; we use other means to achieve the same result. With MOS, the plate-to-slide screws are separate from the sight-to-plate screws. With Gen 6 ORS, it's an insert with lugs; screws go through the RMR and DPP and directly thread into the slide. We don't want lugs to have elasticity or give, when that happens, the load is transferred to the screws, our plate is specifically designed to remove the load transfer to plate-to slide screws.
OPF-G6, DPP has four lugs to support DPP's four lug holes. FCD DPP plates have always had four lugs; it's a bit tricky to do it on the Gen 6 ORS, but we've never taken shortcuts. The OPF-G6 DPP retains the 4-lug feature.
The Gen 6 ORS optics pocket is a bit shorter than the Gen 5 MOS, which makes it impractical to incorporate a full front fence. OPF-G6, DPP has a front fence; it's in two pieces, with the center section omitted. If we installed a continuous fence, the center section would be sharp enough to cut because it's so thin. Another way to achieve a full front fence is to raise the plate above the ORS pocket, doing so will increase the DPP's installed height, it isn't a practical solution for DPP footprint sights that are already rather tall.
All OPF-G6 plates are milled in 17-4 stainless steel. 17-4 stainless is an option we've made available on many of our Gen 5 MOS plates for MIL and LE customers; it's standard on FCD Gen 6 ORS-compatible plates. We don't believe aluminum is suitable for anything that can experience up to 1800G of recoil, especially for sights like P2 and MSP that use a cross bolt. A 1.74oz DPP weighs 163lb in 1500 G of recoil. Will 7075 hold up, and to a lesser degree, will the softer 6061 hold up? We're not taking chances with aluminum. 17-4 SS is more expensive to source and time-consuming to machine; our way has always been about the best we can muster, not the cheapest.
The Gen 6 ORS pocket has a spindle-shaped cavity/depression designed to prevent the plates from rotating or shifting longitudinally and laterally. It also has a small, 45-degree rear locking tab to keep the rear of the plate down. All OPF-G6 plates have a bottom contour to fit and fill out the spindle cavity; they also have a small relief in the rear to engage the ORS pocket's rear locking tab. When installing OPF-G6 plates, insert the rear of the plate into the rear ORS pocket at an angle; then rotate the front of the plate down into the pocket, the same way factory polymer inserts are installed. Glock Gen 6 ORS provides a way to secure the plate in the ORS slide; OPF-G6 and DPP plates take full advantage of the tools Glock provides, for the same reason it has 4 lugs, not just 2.
OPF-G6, DPP does not ship with sight-to-slide screws, as they can vary a great deal and ship with the sights. Leupold DPP ships with M4 0.7 x 15.8mm screws that are too long for other DPP footprint-compatible sights; the torque value may differ as well.
Install the sight using the M4 screws that came with the sight, and use the sight manufacturer's recommended torque value. Glock Gen 6 ORS has four tapped holes; the two farthest apart are smaller screw holes (6-32 for RMR-compatible sights, and the two larger holes closer together are M4 for DPP-compatible sights.
For DPP, the torque value is 25 in lb. If you do not have a Leupold Delta Point Pro, refer to the sight's manual for the recommended torque value. Do not use the M4 0.7 x 15.8 screws unless you have a genuine Leupold DPP, DPP screws are 15.8mm are too long for anything but Leupold's DPP.
Regarding construction, tolerances and material, our position is rather cut and dry and consistent: we make no compromises and take shortcuts with lesser material. We are aware of the harsh conditions in which our plates have been and are expected to be used, that knowledge reinforces our demand for tight tolerances and choice of material, . OPF-G6 tolerances are tighter than the ORS pocket and "good enough", they're designed and made for harsh demands and hard use.

NOTE:
Based on our sample size, the Gen 6 ORS hourglass-shaped depth has a 0.003 swing; this can produce a very slight gap measuring less than 0.001". Depending on the ORS pocket depth, plate thickness, and optics, this gap could exist; it's wholly cosmetic and has no bearing on functionality. The OEM Glock polymer plate doesn't do it because OEM polymer plates are designed to sit slightly above the hourglass cutout, whereas OPF-G6 and DPP are flush with the top of the ORS pocket; DPP sits flush inside the ORS pocket. None of the DPP footprint sights we have seen are 100% flat on the bottom, this isn't a defect, a very small deviation in flatness is acceptable and also doesn't impact functionality.
Below shows the same sight and two plates with a 0.001 thickness difference on the Gen 6 slide, where a small gap exists on both but the gap differs slightly. The same plate and sight can also exhibit this gap on different slides.
