The Night Fision PLATE+BS 509T is a complete mounting and sighting solution for Glock MOS pistols. This package pairs a precision optic plate with co-witnessing iron sights, giving you a ready-to-run setup for shooters who want both a red dot and backup iron sights without fumbling through multiple orders. The plate itself is machined from 17-4 stainless steel and finished with a nitride coating—the same materials and processes that protect firearms from the harshest environments. It's engineered to fit Glock MOS models (19, 17, 45, 47, and other FS MOS variants—Slimline models are excluded) and accommodates the Holosun 509T sight footprint.
Setup is straightforward: the package includes extra screws and an installation tool so you're not hunting for hardware or improvising with your pocket knife. The plate is built to tolerances tight enough to maintain zero through serious recoil, and the iron sights co-witness with most optics that share this mounting footprint, meaning your backup irons stay in the sight picture if your red dot fails or gets obscured. That redundancy matters if you're training seriously or carrying defensively.
Whether you're setting up a duty gun, a competition rig, or a carry pistol with a modern optic, this combo handles the job cleanly. No filler—just solid materials, proven design, and everything you need in one box.
