Correct elevation and windage
cap placement.
Range Sight-In
After bore-sighting the riflescope, select the exact
ammunition you expect to hunt or shoot with and go to
the range for the final sight-in. The Razor HD 1–4x24
riflescope with CQMR-1 reticle and BDC elevation turret
knob is specifically calibrated for two popular loads of the
5.56x45 mm cartridge: the M193 and M855 using a 100
yard zero range.
Note: The Razor HD 1–4x24 CQMR-1 rifl escope can be used
with other cartridges, but the bullet drop references marked on the
elevation turret may not accurately match.
Before range shooting, be sure the reticle is in focus (see
Reticle Focus Adjustment
).
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).
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.
If necessary, make another adjustment to the riflescope
and fire another group to verify zero. This procedure
can be repeated as many times as necessary to achieve a
perfect zero.
After the rifle has been zeroed at 100 yards, the elevation
and windage knobs should be re-indexed to their zero
indicators. This will allow you to accurately keep track of
the elevation or windage corrections dialed on the turrets
in the field and quickly return to an original zero point
setting. The elevation knob must be indexed at zero to use
the BDC references on the elevation knob.
After completing the final sight-in:
• Loosen the three elevation turret cap retaining screws
using the 2.0 mm hex
wrench and carefully rotate
cap until the 100-yard mark
on cap matches up with the
reference line on turret post.
Be sure that the cap is turning
freely and that you don’t rotate
the actual turret mechanism.
• Re-tighten retaining
screws using thumb and
forefinger on short end of
hex wrench.
Repeat procedure with windage turret, aligning the “0” mark
with indicator line.
After making this adjustment, the turret cap’s position will
correspond with the 100-yard zero on the rifle.
