Night Fision Optic Plate + Backup Sight Combo Features The Night Fision Optic Plate and Backup Sight Combo is built around a mounting plate machined from premium 17-4 stainless steel manufactured to tight tolerances for a precise secure fit on full-size Glock MOS models. The nitride coating applied to the plate provides additional protection against wear and the stresses of repeated recoil over time. This plate is designed for the Leupold DeltaPoint Pro footprint along with other optics that share compatible mounting dimensions giving shooters flexibility in optic choice. Each package includes extra screws and an installation tool simplifying setup for users mounting their own optic. Paired with the plate is a set of co-witnessing night sights featuring a yellow tritium front sight and a black rear sight allowing the shooter to align iron sights through the optic window as a reliable backup aiming solution. These sights co-witness with most optics sharing the same mounting footprint ensuring the combo works as a complete system rather than separate components. The combination of a tritium front sight with a durable mounting plate addresses both daylight optic use and low-light backup aiming in a single package. Glock MOS owners running a red dot sight will find this combo a practical well-engineered way to add a true backup sighting system.
