Initial Setup: Place the riflescope into the mounting rings, tightening the clamping screws just enough so that the scope tube can still be rotated freely.
Securing the Tool: Position the ZFIX into one of the Picatinny rail slots and secure it to the firearm using the included rubber bands. Ensure that the ZFIX sits completely flat and flush inside the groove.
Alignment: Look through the eyepiece (ocular) and rotate the riflescope until the crosshairs perfectly align with the horizontal reference lines marked on the ZFIX.
Finalization: Once properly aligned, tighten the mounting ring screws according to the manufacturer's specifications.
