- The scope is sold with its Allen key; use it to unscrew the two lower screws of the mounts. - Slide the scope on the 11 mm rail of your weapon, hold it and very lightly tighten the two screws.
- Position yourself behind the weapon, if you see perfectly in the scope it is correctly positioned.
- If this is not the case, slide the scope in the rail in order to obtain the correct distance between your eye and the eyepiece (8 to 10 cm from your eye).
