RIFLESCOPE
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, 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.

To get the best performance from your Viper HS-T 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. The Viper HS-T riflescope requires
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 height will help assure proper
cheek weld, aid in establishing a solid shooting position, and promote
fast target acquisition.
