Fast Focus Eyepiece

The fast-focuseyepiece 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 thefast-focuseyepiece 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.

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

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 needed after making adjustments to the eyepiece in order to achieve a high resolution, parallax free image.

Elevation and Windage Turrets

The Bushnell Elite Tactical Riflescope features T-Lok (locking) turrets, which provide audible and visual references. When a turret is lifted (elevated) into the upward position it 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. After adjustments are made, the turret can be pushed back into the downward position to prevent movement, or left elevated and ready for further adjustments if preferred.

With the turrets pulled fully upward, 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. Bushnell HDMR and DMR riflescopes provide 5 mils of adjustment per complete revolution of the turret. Bushnell ERS and XRS riflescopes with Z-Stop provide 10 mils of adjustment per revolution.

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

1.Ensure the turret is in the lock position.

2.Use a coin or flathead screwdriver to remove the turret screw found on top of the turret knob, being careful not to displace the o-ringfound under the turret knob.

3.Remove the turret knob and return it to the turret, with the “zero” mark on the knob lining up with the vertical index line on the turret.

4.Return turret screw to top of knob and tighten down, making sure the turret knob is in the locked position so the turret knob does not turn while tightening the screw.

Special Note: Scopes Equipped with theZ-Lok™elevation turret

If your scope is equipped with the Z-Lokzero stop elevation turret, the scope’s windage and elevation controls are positioned in the center of their travel at the factory. This will allow a minimum of 15 mils (or 50 moa) of reticle travel in the up or down direction on the elevation turret. The zero stop is not set at the factory, and will not interfere with reticle travel in the up or down direction. Use of the zero stop is optional and the scope will operate normally with theZ-Lokremaining at the original factory set position.

If you decide not to use the Z-Lok,after zeroing your weapon please refer back to the instructions on page 6, which will help you tore-indexyour turret(s) to the zero position.

If you would like to engage the Z-Lokafter zeroing your weapon please proceed to the next section.

SETTING A ZERO STOP (Z-Stop Models Only)

For ERS and XRS Tactical Scopes with a zero stop feature, follow these steps to initially set your zero stop:

1)Ensure the turret is in its locked position by pressing down on the turret knob. Remove the turret knob cap screw using a coin or flathead screwdriver, set aside (Fig. 1).

2)Remove the turret knob and set aside (Fig. 2). There are two holes on the black inner locking cap which will provide access to the zero stop set screws. Loosen the two Allen screws found on the black inner locking cap 1 ½ turnscounter-clockwisewith the 1.5 mm Allen wrench(provided with your scope) (Fig.3). In order to prevent loss, theset-screwsare permanently held in place by a keeper nut and cannot be completely removed.

3)Pull up the black inner locking cap. Place the long end of the hex wrench in the hole in the top of the black inner locking cap and

push down the brass zero stop (Fig. 4). You should feel the zero stop seat as it hits bottom, the amount of movement is dependent on the location of the zero.

4) Now with the inner locking cap in the up position rotate it in a clockwise direction until you hear a distinct “click” (Fig. 5). This indicates that the zero stop is set at your zero position. Push the inner locking cap to its downward position(Fig. 6).

5)Utilizing the 1.5mm Allen wrench, re-tightenthe zero stop set screws inside the black inner locking cap(Fig. 7). The screws should be tightened until you feel them seat and then an additional ¼ revolution (approximately1.5-2inch pounds).Do not over-tighten as this will cause damage to the screws.

6)Replace the turret knob on to the turret by aligning the splines in the turret cap and the turret and orient your turret to “O” position and seat the cap (Fig. 8 & 9). Once the cap is properly seated insure that the rubbero-ringis in place then replace cap screw and tighten, finger tight with a coin or until snug with a screw driver(Fig. 10).

7)Your zero stop is now set.

RESETTING THE ZERO STOP (Z-Stop™ Models Only)

1)Ensure the turret is in its locked position by pressing down on the turret knob. Remove the turret knob cap screw using a coin or flathead screwdriver (Fig. 1).

2)Remove the turret knob and set aside (Fig. 2). There are two holes on the black inner locking cap which will provide access to the zero stop set screws. Loosen the two Allen screws found on the black inner locking cap 1 ½ turnscounter-clockwise(1.5mm Allen wrenchprovided)(Fig. 3). In order to prevent loss, the screws are permanently held in place by a keeper nut and cannot be completely removed.

3)Place a flathead screwdriver into the cross-slottedscrew located in the middle of the inner locking cap(Fig. 4). Turn the screwdriver clockwise until a stop is felt(do not over tighten the screw at this point to prevent damage to the zero stop). Once the stop is

felt, turn the screw back ¼ turn counter-clockwise(approx. 2.5-3 mils) in order to move the zero stop up off of its lowermost position.
