To get the best performance from your Crossfire II riflescope, proper
mounting is essential. Although not difficult, the correct steps must be
followed. If you are unsure of your abilities, it would be best to use the
services of a qualified gunsmith.
Rings and Bases
Mount an appropriate base and matching rings to your rifle according to
the manufacturer’s instructions. Your new Vortex Crossfire II riflescope
will require 30 mm rings.
Use the lowest ring height that will provide complete clearance of scope
and rifle—avoiding any contact with barrel, receiver, bolt handle or any
other part of the rifle. A low mounting will help assure proper cheek
weld, aid in establishing a solid shooting position, and promote fast
target acquisition.
Begin with riflescope loosely installed in rings on the rifle. Before
tightening the scope ring screws, adjust scope position for maximum
eye relief to avoid injury from recoil.
Eye Relief and Reticle Alignment
• Set the riflescope to the middle of its magnification range.
• Slide the riflescope as far forward as possible in the rings.
• 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.
• Without disturbing the front-back placement, rotate the riflescope until
the vertical crosshair exactly matches the vertical axis of the rifle. Use
of bubble levels, a reticle leveling tool, a weight hung on a rope, or a flat
feeler gauge will help with this procedure.
• After aligning the reticle, tighten and torque the ring screws down per
the manufacturer’s instructions.
Use of bubble levels to square the
riflescope (and reticle) to the base.
