Night Fision GLK-OPBS-507K-43X Optic Plate & Backup Sight Combo - Fits Glock 43X/48 MOS / Holosun 507K

The Night Fision GLK-OPBS-507K-43X Plate Combo pairs a precision-machined optic adapter plate with a matching set of blacked-out backup iron sights, factory-engineered to fit Glock 43X MOS and Glock 48 MOS pistol slides.

The optic adapter is machined from 17-4 stainless steel and cut to the Holosun 507K footprint, accepting Holosun 507K and 407K series red dots as well as other optics sharing that mounting pattern. Tight tolerances lock the plate squarely to the factory MOS slide cut, giving your red dot a secure, repeatable mounting platform that holds zero under recoil during carry and range use.

Paired with the plate are Night Fision's blacked-out backup iron sights at the proper 260-267 height for co-witness use with the mounted optic, providing a durable mechanical aiming reference alongside the electronic sight. The low-profile, blacked-out finish keeps the sight picture clean and snag-free whether running the irons alone or using them as a co-witness backup to the red dot.

This turnkey combo gives Glock 43X and Glock 48 MOS owners an optics-ready setup with co-witness iron-sight backup from a single, well-engineered Night Fision package.
