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.
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.
To visually bore sight a rifle:
Visually bore-sighting a rifl e.
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:
Eye Relief and Reticle Alignment
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, or an adjustable set of feeler gauges
will help with this procedure.
5. After aligning the reticle, tighten and torque the ring
screws down per the manufacturer’s instructions.
Use of an adjustable set of feeler
gauges between a one-piece
base and fl at bottom section
of the rifl escope to square the
rifl escope (and reticle) to the
base.
