ATTACHING A MOUNT, RINGS AND SCOPE TO YOUR RIFLE
WARNING: BEFORE BEGINNING THE MOUNTING PROCEDURE, BE SURE THE ACTION IS OPEN, THE CLIP OR
MAGAZINE IS REMOVED AND THE CHAMBER IS CLEAR. DO NOT ATTEMPT ANY WORK UNTIL YOUR FIREARM
HAS BEEN CLEARED AND DETERMINED TO BE SAFE.
WARNING: IF THE SCOPE IS NOT MOUNTED FAR ENOUGH FORWARD, ITS REARWARD MOTION MAY
INJURE THE SHOOTER WHEN THE RIFLE RECOILS.
In mounting your scope, we recommend that you DO NOT take short cuts as it may lead to damage to either the mounting
system or to the scope. Each mounting system will have its own instructions to follow, and it is best to read the instructions
first to be sure you understand them and have the necessary tools on hand.
We further recommend that you plan to go through the mounting procedure twice. The first time, to be sure everything fits
together and functions properly. On the first run through, please keep the following in mind:
• Before attaching the base, clean the mounting holes in the receiver and the threads of the attaching screws with acetone
or any good solvent to free them of oil or grease.
• If the mount manufacturer has recommended the use of a thread adhesive, do not use it on the first mounting trial. Once
adhesive has set, it is difficult to demount if anything needs correction.
• Be sure the mounting screws do not protrude into the receiver or the barrel.
• When using dovetail mounts, do not use the scope as a lever when installing the scope. The initial resistance to turning
may cause damage to the scope, and is not covered by the warranty. We recommend using a 1” wooden dowel or metal
cylinder to seat the rings.
• Be sure the position of the scope does not interfere with the operation of the action.
• Be sure there is at least 1/8” of clearance between the edges of the rings and any protruding surfaces such as the turret
housing (saddle), power selecting ring, and the flare of the objective bell. Also be sure there is at least 1/8” of clearance
between the objective bell and the barrel.
• You should test position the scope for the proper eye relief. The scope rings should be left loose enough so that
the scope will slide easily. Variable power scopes should be set at the highest magnification when performing this
procedure. Mount the rifle and look through the scope in your normal shooting position.
• Test position the rifle for the proper cheek weld a number of times to ensure that your scope is positioned properly.
• When you are satisfied that everything is okay, demount and start again. This time, seat all screws firmly.
PARALLAX
You may have noticed that placing your eye at different positions behind the scope’s eyepiece causes the reticle crosshairs
to appear to move around to different points on your target. This is called “parallax error” (target and reticle are not in the
same focal plane), and it becomes more noticeable (and more of a problem) at shorter distances and/or when the scope
is set to higher powers. In most cases, parallax will not affect bullet point of impact enough to be of significant concern in
large game hunting situations. Prime models provide an adjustment for parallax compensation (adjustable objective or
side focus knob), which works by moving an optical element until the target (based on its distance) appears in the same
plane of focus as the reticle. All Prime scopes are set at the factory to be parallax-free at 100 yards.
USING THE SIDE FOCUS (Selected High Power Models Only)
The 3.5-10x36 models use a parallax compensation design which adjusts the objective lens at the front of the scope
(“adjustable objective” or “AO”). Models with greater high power capability (12x, 18x) use a movable lens back near the
reticle, so the adjustment can be made with a “side focus” knob placed next to the windage and elevation adjustments.
Just line up the estimated distance to your target with the index dot, and you will eliminate the aiming errors caused by
parallax. After setting the adjustable objective or side focus, you can double check by moving your head around from side
to side behind the eyepiece-the point of aim should not shift if the side focus is correctly set. An alternative method is to
look through the scope and turn the AO or side focus knob until the target, at whatever range, is sharply focused.
PRELIMINARY SIGHTING-IN
You can save a significant amount of expense and frustration by pre-sighting the scope to the rifle before you take it to
the range for zeroing.
There are two basic methods that can be used for pre-sighting your scope. Method one is to use a Bushnell® Bore Sighter
(laser, magnetic or standard). The use of a Bore Sighter saves time and ammunition and is the system most often used by
gunsmiths. The second method is traditional bore sighting:
