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:
Use of an adjustable set of feeler
gauges between a one-piece base
and flat bottom section of the
riflescope to square the riflescope
(and reticle) to the base.
Square the riflescope to the base using flat feeler gauges.
