Windage and elevation markings
The windage/elevation dials are divided into
80 divisions, indicated by vertical white lines. Eachdivision is 1/8 MOA. One full rotation of the dialis equal to 10 MOA. There are two sets ofnumbers (0-9) that appear above the division on
the dial.
Comparing the dial to the windage/elevation scale
below it, you can determine the amount of adjustneeded during sighting in.
Windage/elevation travel is 30 MOA.

It is possible to adjust these model scopes more than this specification
but we suggest the adjustment range be kept within the 30 MOA range(15 MOA each side of centre)
If adjustment is outside of this range we suggest you review themounting system and its alignment to the bore. Being outside thisadjustment range will result in poor optical performance.

How to adjust the reticle focus
While holding the eyepiece, rotate it
counter-clockwise (from theshooter’s perspective) until theeyepiece can move freely.
Looking through scope, aim ateither the sky or a sheet of whitepaper.
DO NOT ATTEMPT TO LOOK
AT THE SUN, AS PERMANENTEYE DAMAGE WILL RESULT.

Locking Ring

Roulette
Eyepiece

When you turn the eyepiece, the reticle’s clarity will change as the focal
length changes. When the reticle is focused for your eyes, turn thelocking ring counter-clockwise until it is firm against the eyepiece.
Do not attempt to over tighten.
How to adjust the zoom setting
When the roulette is all the way in, the scope is at the maximum powerof 55x. To reduce the magnification, hold the eyepiece with your left
hand (if you are right handed) and gently use your right hand to pull theroulette to the rear while turning it counter-clockwise. Pull until theindex point is aligned with your desired power setting.
If the roulette becomes stiff
The roulette may become stiff to move due to lack of use or coldweather. This is due to a settling of the lubricant on the airtight seals
over time, or an increased viscosity in the lubricant at lower
temperatures. Setting the roulette between 40x and 50x when storing thescope will allow enough room to move the roulette either way if it everbecomes stiff to rotate.
