Product Info for Night Fision Optics Ready Stealth Night Sight Set for Sig P365/507k

Night Fision night sights offer a revolutionary new design that with brighter, more vivid, aiming dots. Like all night sights, Night Fision uses self-illuminating Tritium to get the "always on" glow that makes them so effective. Night Fision sights have 30% more Tritium than most sights on the market. The Tritium insert isnt surrounded by a painted-on ring, but rather one made of a daylight fluorescing material that produces optimum visibility in daylight.image

Night Fisions Optics Ready Stealth Series (ORS) sights are engineered to offer a lower 1/3 co-witness with your slide mounted red dot sight. As an alternative to repurposing Suppressor Height sights, ORS sights are designed from the dovetail up to work as back up sights for red dots, obscuring less of the optic window while still allowing three dot sight alignment if needed.
