Night Fision Optic Plate + Backup Sight Combo 509T for Glock MOS

Description

Adding a Holosun 509T to your Glock MOS is one of the best upgrades you can make, but the factory plate that came with your pistol usually won't cut it for the 509T footprint. This combo from Night Fision solves that in one shot. You get a dedicated mounting plate cut for the 509T along with a matched backup sight setup, so your dot sits low and your irons line up right where they should.

What the Night Fision 509T Plate Brings to the Table

The plate is machined from 17-4 stainless steel and given a nitride coating, which is the kind of build that handles years of recoil without loosening up or wearing out. Night Fision holds tight tolerances on these, so the optic seats flush and stays put. It fits full-size and compact Glock MOS models, and the same 509T footprint works with a handful of other optics too, so check the pairing guide if you're running something besides the Holosun.

Backup Sights That Play Nice With Your Red Dot

This is where the combo earns its keep. It ships with the .330-.353 Optics Ready Stealth blade height, tuned specifically for a lower 1/3 co-witness once the 509T is mounted on the plate. Up front you get a tritium sight for glow that never quits in low light, and the rear is a blank blade with anti-glare serrations. That setup keeps a clean, uncluttered sight picture so your dot does the heavy lifting while the irons wait quietly in the background for when you need them.

Installing the Night Fision Combo Pack

No filing, no fitting, no guesswork. The kit includes extra screws and an installation tool that doubles as a sight adjustment driver, so you have what you need to get the plate torqued down and the optic mounted in one sitting. If you've been putting off the red dot build because you weren't sure which plate and sight heights to buy, this takes the math out of it and hands you a matched set that just works together.
