Range Sight-In and RZR Zero Stop Set

After the riflescope has been bore-sighted, final
sight-in and RZR Zero Stop set should be done at the
range using the exact ammunition expected to be used
while shooting. Sight in and zero the riflescope at the
preferred distance. 100 yards is the most common
zero distance, although a 200 yard zero may be
preferred for long distance applications.

Be sure the reticle is in focus (see Reticle Focusing) and
set the parallax adjustment to match the distance being
used for sight-in:

1. Following all safe shooting practices, fire a three-shot
group as precisely as possible.

2. Next, adjust the reticle to match the approximate
center of the shot group (see section on Windage and
Elevation Adjustment). As previously noted in the section on
bore sighting, the elevation turret cap turret should be removed
and zero stop lock screws should be loosened.

3. If the rifle is very solidly mounted and cannot be
moved, simply look through the scope and adjust the
reticle until it is centered on the fired group.

4. Carefully fire another three-shot group and see if the
bullet group is centered on the bullseye.

This procedure can be repeated as many times as
necessary to achieve a perfect zero.

After satisfactory zero has been obtained, the RZR zero
stop can be set:
1. Re-tighten the three zero stop lock screws. Do not over tighten:
thumb and forefinger on the short end of supplied hex wrench
will be sufficient.

2. Replace elevation turret cap, being sure to align “0” mark
on cap with the zero reference line on scope body. Push the cap
straight down and avoid turning while doing this.

3. Be sure the cap is fully down and re-tighten elevation cap
retaining screws. Do not overtighten: using thumb and forefinger
on short end of hex wrench will be sufficient.

Note: To re-zero for a different load, repeat complete bore sighting and range
sight-in procedures. It is important to always begin any sight-in adjustments
by turning elevation turret clockwise until fully stopped.

Re-Indexing Zero Mark on Windage Knob

If desired, the windage knob may be re-indexed to zero after
sight-in. This will allow an easy return to the zero point if
temporary windage corrections are dialed in the field.

1. After completing the final sight-in, fully loosen the three
windage turret cap retaining screws and carefully pull the turret
cap straight off. Re-position with the “0” mark on the cap aligned
with the zero reference line on the turret post and push the cap
straight down. Avoid rotating while pushing down.

2. Be sure the cap is fully down and re-tighten windage knob
retaining screws. Do not overtighten: using thumb and forefinger
on short end of hex wrench will be sufficient.
