Night Fision Optics Ready Stealth Series backup iron sights for the Glock 17, 19, and 34. They sit at suppressor / optic height (.290″ front, .313″ rear) for a lower one-third co-witness with a directly-milled or MOS-cut red dot — RMR, Holosun 507c / 407c, 508t, and similar battery-pack-height optics — no mounting plate required.
This is the blank (blackout) configuration: blacked-out front and rear that stay out of your optic window while still giving you an iron reference behind the dot. Machined steel with a square-notch rear.
