The Night Fision Optic Plate & Blank Sight Combo GLK-OPBS-507K-43X-ZXZX is a precision-engineered mounting solution designed for Glock Slimline MOS pistols, specifically the Glock 43X MOS and Glock 48 MOS. This combo pack includes a high-quality optic plate that adapts the factory RMSc footprint to the popular Holosun 507K footprint, along with a set of blank backup sights. This allows Glock 43X and 48 MOS owners to mount micro red dot sights such as the Holosun 507K, 407K, or EPS Carry while maintaining the option to install their preferred iron sights later.
Why Choose the Night Fision Glock 43X MOS 507K Optic Plate Combo?
Glock Slimline MOS pistols come with an RMSc optic cut from the factory, which limits direct compatibility with many popular micro red dots. The Night Fision GLK-OPBS-507K-43X-ZXZX solves this compatibility issue by providing a robust adapter plate that converts the RMSc cut to accept 507K footprint optics. The included blank sights give shooters the flexibility to install their own tritium, fiber optic, or standard iron sights. This makes the combo ideal for custom builds, competition shooters, or anyone who prefers to choose their own backup sight system rather than being locked into pre-installed tritium sights.

Performance and Build Quality
The Night Fision Optic Plate & Blank Sight Combo is built with the same attention to detail and quality that Night Fision is known for. The optic plate is machined from solid steel and finished for corrosion resistance, ensuring a secure and stable platform that maintains zero even under heavy use. Because the sights are blank, shooters have complete freedom to install their preferred sight system — whether that’s tritium night sights, fiber optic sights, or suppressor-height sights. This flexibility makes the GLK-OPBS-507K-43X-ZXZX an excellent choice for custom Glock builds and shooters who want full control over their sighting system. The plate is designed for easy installation and provides a clean, low-profile mounting solution for popular 507K footprint optics on Glock Slimline MOS pistols.
