Night Fision Perfect Dot Green Tritium Square Rear Suppressor Height Sig P Set Black. The patented tritiumGreen Dot SightSystem by Night Fision consists of a unique ProGear LitePipe with a ProGear Urethane Dot and a serrated TrijiconProGear LiteBar. ProGearTion produces an ultra-bright aiming dot and aggressive angled Utility Serrations that extend the life of the sight blade in front of the rear iron sights. Unlike a typical slanted or angled square the Perfect Dot has a smooth radiused outside edge that allows for faster front sight acquisition. The serrations on the rear sight not only make the sight look great but they offer better control of the weapon when holstered or dismounted. The Perfect Dot is a Night Fision original product designed for the nonnegotiable feature of having the ability to use any ammunition in any configuration under any light condition. Once exposure to a bright light the tritium glow enhances the shooting experience and quickens sight acquisition. This is the same product that is used on the Night Fision PRODUCT model. They are simply the best shooting sights that we have tested.
