Z-Lok Zero Stop

Z-LOK™ ZERO STOP

Bushnell's Z-Lok™ Zero Stop is a mechanical zero-stop available on select riflescopes. 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 the Z-Lok remaining at the original factory set position. It is simple to set, and offers assurance that you will not accidentally wind back below where you have your scope's zero set.

USING THE Z-LOK™ (ZERO STOP)

1. After obtaining a good zero on your rifl e at 100 yds, use the provided Allen wrench to loosen all 3 set screws around the top cap of the turret cover, being careful not to remove the set screw completely (Fig. 5)

2. Remove the turret cover and set it aside (Fig. 6).

3. Loosen the three Allen set screws found on the perimeter of the brass inner locking ring 1½ turns (using the provided 1.5mm Allen wrench) (Fig. 7). These screws are “captured” in the Z-Lok ring so that they cannot be completely removed and dropped or lost. Ensure the screws are loosened far enough for the Z-Lok disk to “bottom out” before you turn it in the next step.

4. Turn the Z-Lok disk clockwise (Fig. 8) until it contacts the fi xed pin in the bottom of the turret (Fig. 9).

5. Tighten the three set screws in the Z-Lok disk to 2 inch lbs (Fig. 10) (do not overtighten). Your zero stop is now set.

6. Re-index the turret cap to zero, replace the turret cover, and re-tighten the turret cover set screws.
