FAST FOCUS EYEPIECE

The fast-focus eyepiece dial is found on the ocular end of the Bushnell Elite Tactical Riflescope. Use this adjustment to obtain a
reticle image that appears sharp to your eyes. If adjustment is needed, look at a distant object for several seconds without using your
scope. Then, shift your vision quickly, looking through the scope at a plain background. Turn the fast-focus eyepiece dial clockwise
or counterclockwise until the reticle pattern is sharp and clear. The eyepiece has a large adjustment range and should be used in

conjunction with the side focus (parallax) adjustment* to obtain maximum resolution when viewing targets at long ranges (*on high
power scopes that provide it).

POWER CHANGE RING

Changing the magnification of the Bushnell Elite Tactical Riflescope can be accomplished by grasping the
knurled knob marked with the scope’s magnification range (located on the far end of the ocular bell end).
Turn the power change ring clockwise for higher magnifications, counterclockwise for lower magnifications.
The magnification setting can be identified by noting the number that is in front of the stationary dot on the
scope tube.

SIDE FOCUS (high power models only-see Parts Guide)

The Side Focus adjustment corrects Parallax error. Parallax error is experienced when the intended target and the reticle are not on the
same focal plane. The side focus adjustment relocates an optical element within the scope, manipulating the incoming image to appear
on the same focal plane as the reticle within the riflescope, thus eliminating parallax error. Parallax error results in inconsistencies
regarding point of impact. This can be best experienced by looking at a 100 yard target with the side focus set to 500 yards. While
slightly moving your head left and right, or up and down, you will notice movement at the location where the crosshairs intersect.
However, if you change your side focus adjustment to 100 yards while looking at the 100 yard target, the intersection of the crosshairs
will not move.

Please note the distance markings on the dial are intended as reference points only. Exact side focus adjustments may be needed after
making adjustments to the eyepiece in order to achieve a high resolution, parallax free image.

FIRST FOCAL PLANE AND SECOND FOCAL PLANE RETICLES

Some models of Bushnell Elite Tactical Riflescopes described this manual have their illuminated reticles located in the first focal plane,
while others place the reticle in the second focal plane. If the reticle is within the first focal plane, it will increase in size when the
magnification is increased. This feature allows the continued use of the mil measurement system contained in the reticle, regardless
of the power setting. Second focal plane reticles restrict the user to making measurements at a specific power, as the reticle remains
the same size regardless of the magnification level.

BORE SIGHTING AND ZEROING THE SCOPE

Bore sighting is a preliminary procedure to achieve proper alignment of the scope with the rifle bore. It is best done using a Bushnell
Bore Sighter. If a bore sighter is not available, it can be done as follows: Remove the bolt and sight through the gun barrel at a 100 yard
target. Then sight through the scope and bring the crosshairs to the same point on the target using the turrets or windage adjustments.
Return the bolt and prepare to shoot down range at the 100 yard target.

Your next step will be to zero the scope using live rounds. Fire your first shot and note the location of impact. You can use the elevation
and windage adjustments to change the point of impact accordingly. For example, if your first shot went 1 mil high and 1 mil left, adjust
your elevation dial down 1 Mil and your windage dial 1 mil right. Always adjust in the opposite direction from your point of impact.

As you fire your second shot, you should see the point of impact hit closer to your intended target. Multiple rounds may need to be fired
before achieving consistent results. You may also use reticle within your scope to help decipher the correct adjustments. The following
page shows how this works, using the BTR-Mil reticle as an example.

7

In the example to the left using the BTR-Mil reticle, the shooter was
attempting to hit a target in the center of the crosshairs. The actual point
of impact hit 4 Mils down and 3 Mils left, as indicated by the red dot.
Adjust the elevation dial 4 Mils up/windage dial 3 Mils right. Another way
to accomplish this is to return the weapon to the original aiming point
on the target. Ensure that it is securely held in place. While holding the
weapon steady, adjust the elevation knob until the horizontal cross hair
intersects the bullet hole made by the first shot. Then adjust the windage
knob until the vertical cross hair intersects the original bullet hole. The
rifle scope should now be closely aligned with the bore of the weapon.
It is advisable to fire additional shots as some fine adjustments may be
required to insure that the firearm is perfectly zeroed.

ELEVATION AND WINDAGE TARGET TURRETS (3-12x44 & 6-24x50 MODELS)

Selected models of Bushnell Elite Tactical Riflescope with illuminated reticle feature target style adjustment turrets, which provide
audible and visual references. The turrets can be rotated in either direction to make appropriate adjustments.

Each turn of the turret provides an audible “click” which coincides with a movement of the visible reference point on the turret knob.
Additionally, clicks can be felt by your fingers as the turret knob moves. Each “click” represents .1 mil of reticle movement.

Rotate the elevation turret knob counterclockwise to move the reticle plane up, or clockwise to move it down. Rotate the windage dial
counterclockwise to move the reticle plane right, or clockwise to move it left. These Bushnell Tactical Riflescopes provide 5 mils of
adjustment per complete revolution of the turret.

After adjustments have been made, you can reset the turret to zero by following the procedure below:

REMOVING THE TARGET TURRETS

Using the included Allen wrench (hex key), loosen the turret bolt (A) by turning it counter-clockwise while firmly holding the turret in
place. You can either remove the bolt entirely (B), or just loosen it enough to be able to pull up on the turret and rotate it freely in either
direction (make sure the adjustment itself does not change-you don’t want to loose your zero setting).

RESETTING THE DIALS TO ZERO

Once the turret bolt is loose (or removed), and you are able to pull up the elevation turret and rotate it freely, line up the “0” on the
adjustment scale with the index line, then push the turret back down into place (C). Be careful not to lose any clicks when pushing the
turret back down, which might affect your targeting at the next use. Replace the turret bolt and use the Allen wrench to tighten it (turn
clockwise) until the turret is securely in place. Repeat this process with the windage turret.
