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 turns counter-clockwise with the 1.5 mm
Allen wrench (provided with your scope) (Fig.3). In order to prevent loss, the set-screws are 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).
