Night Fision RMR Optic Plate + Backup Sight Combo Features The Night Fision Optic Plate and Backup Sight Combo is machined specifically for the Sig Sauer P320 Pro Cut footprint mounting a Trijicon RMR Holosun 507C or any optic sharing that compatible footprint. The plate is cut from premium 17-4 stainless steel at tight tolerances giving it the strength needed to stand up to the repeated recoil impulses a duty or carry pistol generates. A nitride coating adds corrosion resistance on top of the stainless construction and the plate measures a slim 0.2 inch thick to keep the overall slide profile low. This combination keeps the optic secure and co-witnessed through heavy round counts. Alongside the plate the package includes a tritium front night sight with a yellow front and black rear letting the shooter co-witness through the optic window in low light or if the red dot ever goes down. Extra mounting screws and an installation tool are included in the box so setup does not require sourcing separate hardware. The sights are built to the same demanding co-witnessing standard Night Fision applies across its product line. P320 Pro Cut owners running an RMR or 507C gain a complete duty-ready mounting and backup sighting solution in one package.
