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.
