Night Fision sights ship with more material on the dovetail to ensure a tight fit with the inherent variations found in manufactured firearms slides. As a result, they may not seat in the dovetail deeply enough to be installed until some material is removed. First check to see how far the sight seats in the dovetail before attempting to install your sights. For a detailed guide, please download our installation guide. If you are unsure how to remove material with the stone, please have a gunsmith or experienced armorer complete the installation of your sights.

Night Fision uses 30% more Tritium in an effort to give you the brightest, longest lasting glow on the market. That comes with a larger sight vial. We only recommend using the RealAvid Sight Pusher sight pusher with the Narrow Head as low as possible on the sight blade. A non-marring punch can also be used, but as with the sight pusher the contact point must be as low as possible on the sight body to avoid compressing the vial under pressure.

If your sight has a set screw, we recommend 5-7 in/lb, or hand tight. Do not overtighten, as it may strip the threads on the set screws.

All set screws come with blue Loctite pre-applied, we caution against using red Loctite or Vibratite as it may make removal extremely difficult, and the potential to strip your set screws should you need to remove the sight. 

Only use the front sight screw that comes with your Night Fision Night Front Sights, as some OEM front sight screws may not be compatible.
