OUNTING
To get the best performance from your Viper HS LR 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 Vortex Viper HS LR riflescopes
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 height will help assure proper
cheek weld, aid in establishing a solid shooting position, and promote fast
target acquisition.
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 your face. Pay
attention to the field of view. Stop sliding the riflescope back as soon
as you see the full field of view.
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 a bubble level will help with this procedure.
After aligning the reticle, tighten and torque the ring screws down per the
manufacturer’s instructions.
