USAGE

Focusing Look through scope within 3 or 4 inch distance from your eye to eyepiece lens.If you can’t see the reticle clearly,loosen knurled lock ring and rotate eye bell until the reticle appears clearest.Then screw the lock ring to lock the eye bell firmly.

Mounting Scope is installed on gun by means of mount.Rotate scope tube so that vertical crosshair is vertical and horizontal crosshair is horizontal.Adjust the position of scope on the rifle so that proper eye relief is achieved.Then tighten all screws to fix scope on the rifle firmly.

Boresighting Aim at a target 100 m away and fire at it.If the impact point deviates from the aiming point,measure the vertical and horizontal distance between these two points.Screw off upper and right handwheel covers of the scope and turn two handwheels in the direction showed in the table below.Keep on firing and adjusting until the impact point coincide with the aiming point.

CAUTION: One click on handwheel equals to 1/2 or 1/4 inch displacement on the target 100m away(see performance parameter table).
