Before the final tightening of 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 a reticle leveling tool, plumb
bob, or an adjustable set of feeler gauges placed between a
one-piece base and the flat bottom of the riflescope’s center
section for this procedure.
5. After aligning the reticle, tighten and torque the ring
screws down per the manufacturer’s instructions. Use
caution and do not over-tighten.
To make the adjustment:
Bore Sighting
Initial bore sighting of the riflescope will save time and
money at the range. This can be done using a mechanical
or laser bore sighter according to the manufacturer’s
instructions. On some rifles, bore sighting can be
accomplished by removing the bolt and visually sighting
through the barrel.
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 you can visually center the
target 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:
Note: If you are using rings which permit windage adjustments, make
your initial bore sighting windage adjustments with the rings as much
as possible.
Sighting in the Rifle
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.
Square the riflescope to the base using flat feeler gauges.
