OUTSTANDING BRIGHTNESS: Night Fision offers innovative night sights with brighter, more vivid aiming dots which utilize self-illuminating Tritium for a constant glow, making them highly effective; the sights contain 30% more Tritium than most competitors do

SHARP SIGHT PICTURE: The domed lens of the sights collimate tritium rays, which helps to provide a sharper sight picture, this feature allows the shooter to have a clearer view of their target, making it easier to aim accurately; instead of a painted-on ring, the Tritium insert is surrounded by a daylight fluorescing material, ensuring optimal visibility in daylight
