ZEROING

Bore sighting is a preliminary procedure to achieve proper alignment of the sight with the rifle's bore.

Mount the rifle with the riflescope installed on a bench rest.
Aim at a target 100 meters away.
Turn on the riflescope, adjust display brightness and achieve a sharp image of the reticle.
Rotate the lens focus knob (15) to achieve a sharp image of the target.
Take aim and shoot at the centre of the target.
If the point of impact did not match with the aiming point, unscrew the caps of windage (11)/elevation (12)
turrets and use the turrets to line up the centre of the reticle and the point of impact.
Take two shots. If required, re-adjust the reticle.
