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

The Night Fision GLK-OPBS-507K-43X-YGZX is a matched optic mounting plate and backup tritium night sight combo engineered specifically for the Glock 43 MOS, Glock 43X MOS, and Glock 48 MOS pistol platforms. Designed around the Holosun 507K / 407K red dot footprint, the package pairs a rugged, optics-ready mounting base with a co-witness set of backup iron sights so a defensive Glock Slimline MOS can be set up with a subcompact red dot and a usable iron backup in one go.

The mounting plate is machined from premium 17-4 stainless steel and finished in a low-glare black nitride coating for outstanding wear and corrosion resistance. Built to tight tolerances to fit the Glock Slimline (43/43X/48) V1 MOS optics cut, the plate securely seats a K-series reflex red dot and is engineered to stand up to the recoil of defensive 9mm loads over years of carry use.

The included Night Fision backup night sights are set to the proper co-witness height of 260-267 so a usable iron sight picture lines up through the lower window of the mounted optic. Tritium inserts on the yellow front and green rear use Night Fision's patented dome technology, advertised as 30% brighter than standard night sights, keeping the sight picture fast and intuitive in low-light and no-light conditions without any dependence on batteries.

Backed by Night Fision's reputation for premium aftermarket Glock sights and accessory hardware, the package includes the optic mounting plate and the matched front and rear backup tritium night sights, ready to install on a V1-cut Glock Slimline MOS slide.
