Night Fision PLATE+BS 509T FITS GLOCK FS MOS$89.99
Availability: In Stock
The Night Fision PLATE+NS 509T is a complete optics mounting and backup sight solution built for Glock full-size MOS pistols. This combo pairs a precision optic plate with a lower-1/3-cowitness sight set, giving you a dependable iron-sight backup that stays in your sight picture when your red dot is on target. If you're running a Holosun 509T or compatible optic on a modern Glock MOS slide, this system lets you stay effective in any light condition without fumbling between sight planes.
The optic plate itself is machined from 17-4 stainless steel and finished with a nitride coating—a proven combination for durability under hard use. It's engineered to tight tolerances so your optic sits rock-solid on your slide, and Night Fision includes extra screws and an installation tool so you can get set up without a trip to the gunsmith. The .2-inch thickness keeps your mounting profile clean and manageable.
The backup sight package ships with a tritium front sight paired to a blank rear, both cut for lower-1/3-cowitness height. The tritium front glows in low light without a battery, and the rear sight features anti-glare serrations to keep glint minimal and your sight picture clean. It's the setup you'd spec for yourself if you were building a duty or defensive Glock from the ground up.
This is not a plate-only or sights-only buy—you get the complete package, ready to turn an optics-cut Glock into a modern, fast-sighting pistol.
