Once the sight is installed on the Hi-Rise block, the entire assembly can be mounted on the weapon. First, loosen the mounting screw so that the clamp will fit over the tapered side of the firearm€™s Picatinny or Weaver rail. Ensure that the tapered clamp on the riser is oriented with the chamfered (beveled) end of the clamp at the top. Ensure that the riser€™s cross screw with nut is tightened to clamp it firmly to the weapon€™s rail. Turn the large nut on the riser block ¼ to ½ turn with a coin, screwdriver or ½€ wrench. WARNING! Do not over tighten.
