Night Fision Optic Plate + Backup Sight Combo Features The Night Fision Optic Plate and Backup Sight Combo is built around a precision mounting plate machined specifically for the Holosun EPS Carry footprint on Glock MOS Slimline models including the 43X and 48. The plate is cut from premium 17-4 stainless steel to the tightest tolerances giving it the strength to withstand the repeated recoil impulses a defensive or duty pistol generates over its service life. A nitride coating adds further corrosion resistance on top of the stainless construction. This combination keeps the optic mounted securely and co-witnessed through thousands of rounds of use. Alongside the plate the package includes a tritium front night sight with a yellow front and black rear allowing the shooter to co-witness through the optic window in low light or in the event the red dot sight goes down. Extra mounting screws and an installation tool are included in the box making setup straightforward without sourcing additional hardware. The sights are built to the same demanding standard Night Fision applies across its lineup of co-witnessing night sights. Glock 43X and 48 MOS owners running a Holosun EPS Carry gain a complete duty-ready mounting and backup sighting solution in one package.
