Step-by-Step Installation

1. 1. Watch the video first
      Start by watching Night Fision’s installation video to get the overview of each step. That visual reference will help you understand each of the following steps. (Watch on Youtube)
   2. Workspace
      Unbox the plate and all hardware. Set your plate screws aside from the optic screws needed for your optic. We clearly mark all included hardware, including the recommended optic if there are multiple screw packs (such as the RMR plate). Ensure your firearm is cleared and field strip the firearm so you separate the slide from the frame. On Glock pistols, we recommend ensuring your extractor channel does not have parts to avoid any entrapment issues. Set all parts aside and keep the slide you plan on installing the plate and optic to in the center of your well-lit workspace.
   3. Prepare the Surface
      Clean the top of the optic cut on the slide with a solvent that removes all oil, lubricant, and debris from the surface.
   4. Test-fit the plate
      We guarantee our plates to show up with zero warp and machined to the tightest tolerances. It is still critical to ensure you “dry fit” or test fit the plate-to-slide fit before screwing down and securing the plate—putting the plate down on the slide, and ensuring there is little to no movement (unsecured there may be some), that there is no issues with the slide cut (non-OEM slides may have different tolerances, our plates are cut to precisely mate with the strict tolerances of the Original Equipment Manufacturer). We also encourage putting the optic down on the plate to ensure there are no errors made in the footprint.
   5. Secure the plate
      Once you have ensured there is no issue in the test-fitting stage, use the plate screws to secure your plate. Tighten them using 5–7 in/lb of torque (or “hand tight” if you don’t have a torque driver) with our provided Installation Tool. Alternate your tightening of the screws to ensure the plate stays as level as possible during this process. The screws will have blue Loctite pre-applied. Avoid red Loctite or Vibratite, since they can make removal very difficult or risk stripping threads. Should you choose to use Red Loctite or Vibratite, it is strongly recommended that you use heat to break down the bond before attempting to remove or loosen screws.
   6. Witness Marking
      Use a paint marker to make some small marks that extend from the screw head out to the plate as a helpful way to visually see if the screws begin to loosen when/if inspected when the optic is removed. Wait until the paint has dried before moving on to the next step.
   7. Mount your optic
      Now that the plate is installed, align your optic over the mounting holes and attach it per the optic manufacturer’s instructions. Use the matching footprint and torque specs, and ensure it’s centered and flush. As with the plate, it’s recommended you alternate your tightening, and witness mark your screws when complate.
   8. Final checks
      • Make sure everything is tight but not over-torqued
      • Confirm the plate and optic are seated with no gaps
      • Install any previously removed slide internals
      • If your setup involves co-witnessing sights (e.g. lower 1/3), double-check your sight heights and alignment
      • Let your slide with it’s new plate and optic cure for 12-24 hours for best results
      • It’s recommended you test fire your firearm to ensure everything is working properly
