Bore Sighting
Initial bore sighting of the riflescope will save time and money at the
range. This can be done by using a mechanical or laser bore sighter
according to the manufacturer’s instructions or by removing the bolt and
sighting through the barrel on some rifles.
To visually bore sight a rifle:
1. Place the rifle solidly on a rest and remove the bolt.
2. Sight through the bore at a target approximately 100 yards away.
3. Move the rifle and rest until the target is visually centered inside the
barrel.
4. With the target centered in the bore, make windage and elevation
adjustments until the reticle crosshair is also centered over the target.
Note: Be sure to read pages 11–12 prior to making adjustments.

Eye Relief and Reticle Alignment
After installing the bottom ring halves on the mounting base, place the
riflescope on the bottom ring halves and loosely install the upper ring
halves. Before tightening the scope ring screws, adjust for maximum eye
relief to avoid injury from recoil:
1. Set the riflescope to the middle of its magnification range.
2. Slide the riflescope as far forward as possible in the rings.
3. While viewing through the riflescope in a normal shooting position,
slowly slide the riflescope back towards the shooter’s face—paying
attention to the field of view. Just as the full view is visible, stop.
4. Without disturbing the front-back placement, rotate the riflescope
until the vertical crosshair exactly matches the vertical axis of the rifle.
Use of a reticle leveling tool, a weight hung on a rope, flat feeler gauges,
or bubble levels will help with this procedure.
5. After aligning the reticle, tighten and torque the ring screws down
per the manufacturer’s instructions.
