Weaver part numbers for detachable top mounts, rings and side mounts, and pivot
mounts are available by firearm make. Enter your make in the space provided or
select one from the scrolling list for details.
- 1. Scope Maintenance
- Maintain the metal surfaces of your scope by removing any dirt or sand with a
soft brush to avoid scratching the finish. Wipe the scope with a damp cloth and
follow with a dry cloth. Finally, wipe with a silicone treated cloth to restore
luster and protect the scope against corrosion. Be careful not to touch the lenses
with the silicone cloth. Back to top
- 2. Focusing the Eye Lens
- 1. Hold scope about three inches from your eye.
2. Quickly glance through the scope at a featureless area, such as a wall or
the open sky.
-
- CAUTION: DO NOT LOOK AT THE SUN AS PERMANENT EYE DAMAGE, EVEN BLINDNESS MAY RESULT.
- 3. If the reticle did not instantly appear in sharp focus, loosen the eye bell
locking ring, rotate the eye bell in either direction until reticle is sharply
focused.

- 3. Attaching Scope to Mount
- 1. Remove ring caps from mount, place scope in cradle formed by uncapped rings.
2. Slide scope fore or aft to position scope at the proper eye point so a full
field of view can be seen.
3. Rotate scope to align the reticle horizontally and vertically.
4. Replace ring caps and tighten firmly. Back to top

4. Pre-Zeroing
- If available, use a bore-sighter collimator to pre-zero your rifle.
At an approved range, or other safe area, bench rest the rifle. Remove the windage
and elevation caps. If you have a bolt action rifle, remove bolt. If you have
a lever, pump or semi-auto loading rifle, use a mirror type bore sighting device,
available from your gun retailer.
If you have a zoom power scope, turn the power change ring to the highest setting.
If your scope model is equipped with an adjustable objective lens mount for a
parallax correction, rotate the focusing ring to the appropriate standard-parallax
setting.

Sight through the bore at a target of 100 yards. Move the rifle about to center
the target in the bore.
Sight through the scope and adjust the windage and elevation screws to center
the target on the reticle.
NOTE: Never force the windage and elevation screws past their natural stop. Internal
damage can result rendering the scope inoperative. The most common occurrence
with "over-adjusting" includes: power change system jamming, broken lenses, poor
image quality, insufficient grouping of shots, and limited or irregular movement
of Point of Impact alignment.
- 5. Final Zeroing Back to top
- Since final zeroing involves live fire, check bore to be sure it is free of any
obstructions before loading. Use eye and ear protection.
Fire three rounds at your target. Note impact on target. Measure the distance
from group center to target center.
Adjust the windage and elevation screws accordingly. Each click adjustment will
move the bullet impact by the amount shown on the dials (type C or D) at 100 yards.
NOTE: Never force the windage and elevation screws past their natural stop. Internal
damage can result rendering the scope inoperative. The most common occurrence
with "over-adjusting" includes: power change system jamming, broken lenses, poor
image quality, insufficient grouping of shots, and limited or irregular movement
of Point of Impact alignment.
If the bullet hits were more than 3 inches (12 inches/100 yards) apart from where
you aimed at, you have problems with your mounting system.
Replace windage and elevation caps when zeroing is completed.
Each click of adjustment will move the bullet impact by the amount shown at the
distance indicated.

The following information is to assist you in properly zeroing your scope.
Normally, not more than six to eight inches of adjustment are required for zeroing.
In extreme cases, ten to twelve inches are needed. We suggest you carefully check
your mounting system first.
Your scope is optically centered now, which means the erector system in your
scope sits right in the middle of the scope's tube. Any adjustments made using
the W/E dials will move the erector system from the center. Please make sure that
you can zero the Point of Impact (bullet impact point) and Point of Aim (crosshair
point) without using excessive amount of W/E adjustment. |
FOR THOSE WHO DO NOT HAVE A BORE-SIGHTER:
- Mount your scope on your rifle and tighten all screws.
- Set the target at 25 yards.
- From bench rest, aim at the center of your target and shoot 2 or 3 rounds.
- Examine your target, check how far your Point of Impact (POI) is from your Point
of Aim (POA).
- If the bullet hits were more than 3 inches (12 inches/100 yards) apart from where
you aimed at, you have problem(s) with your mounting system.
Do not use W/E adjustment screw. Adjust the mounting system first. |

FOR THOSE WHO ARE USING A BORE-SIGHTER:
- With the top portion of your mounting rings open, put your riflescope on your
rings, determine how far the center of your crosshairs is from the center of your
bore-sighter grid.
- If they are more than 3 squares (12 inches/100 yards) apart from each other,
you have problem(s) with your mounting system.
Do not use W/E adjustment screw. Adjust the mounting system first. |
| NOTE: Never force the W/E screws past their natural stop. Internal damage can
result rendering the scope inoperative. The most common occurrence with "over-adjusting"
includes: power change system jamming, broken inner lenses, poor image quality,
insufficient grouping of shots, and limited or irregular movement of POI alignment. | |
