Night Fision DPP Optic Plate + Backup Sight Combo Features The Night Fision DPP Optic Plate + Backup Sight Combo is machined from 17-4 stainless steel a material chosen specifically for its ability to handle the repeated recoil impulses a duty or competition pistol generates without loosening or deforming over time. A nitride coating adds a further layer of corrosion and wear resistance keeping the plate functioning reliably through heavy use and exposure to the elements. The plate uses the Leupold DeltaPoint Pro and Sig Romeo Pro mounting footprint which means it also accepts any other optic built to that same standard giving the shooter flexibility in optic choice. Every plate is held to tight manufacturing tolerances so the optic sits square and secure with no play once installed. Because the combo ships with Night Fision s own co-witnessing sights the shooter gets a matched backup sighting system in the same package as the mounting plate rather than sourcing sights separately. These sights are set up to co-witness properly with optics sharing the DeltaPoint Pro footprint so the irons line up through the optic window as a dependable backup if the dot ever fails. The package includes extra mounting screws and an installation tool which simplifies setup and gives the shooter spares on hand for future reinstalls. Built to fit full-size Glock MOS models this combo gives Glock MOS owners a complete co-witness-ready optic mounting solution in one purchase.
