Quick answer

Mount the ZEISS Conquest V4 4-16x50 in 30mm rings, bore sight at 25 yards, then zero at 100 yards using the 1/4 MOA turrets. Confirm parallax is set correctly and fine-tune with the ASV Ret 93 reticle for your hunting distance.

Why the 30mm tube and 1/4 MOA clicks matter for setup

The 30mm main tube gives you more internal adjustment range than a 1-inch tube, which is helpful when you need to compensate for ring misalignment or shoot at longer distances. Each click moves impact by 1/4 MOA, so at 100 yards one click equals roughly 0.26 inches. That precision is an advantage, but it also means you should count clicks carefully and record your zero settings.

When to use the side-focus parallax adjustment

The side-focus parallax knob adjusts from 9.1 meters to infinity. For most hunting situations, set it to match your target distance to keep the reticle steady. If you forget to adjust parallax, you may see the reticle move slightly when you shift your eye, which can cause missed shots at longer ranges. Always recheck parallax after changing magnification or distance.

Step-by-step setup and zeroing

  1. Mount the scope with correct ring alignment: Install 30mm rings on a Picatinny or Weaver base, leaving the scope loose enough to rotate. Use a torque wrench to tighten ring screws to the manufacturer’s specification (typically 15-18 in-lbs). Check that the reticle is level using a plumb line or leveling kit before final tightening. A canted reticle will cause horizontal drift at longer distances—double-check level before torquing.
  2. Set eye relief and tighten the rings: With the scope mounted, adjust it forward or backward until you see a full, clear image without shadows at 4x magnification. Then tighten the ring caps evenly in an X pattern to the recommended torque. Eye relief changes with magnification; set it at the highest power you plan to use most often.
  3. Bore sight at 25 yards: Remove the bolt (or use a bore-sight tool) and look through the barrel at a 25-yard target. Adjust the turrets until the bore and the scope’s reticle center align on the same point. This gets you on paper quickly and saves ammunition. If you can’t align the bore and scope, check for ring misalignment or a base that isn’t seated properly.
  4. Fire a three-shot group at 100 yards: Use a stable rest and aim at the center of a large target. Fire three shots, then measure the group’s center from the point of aim. Make turret adjustments based on the average impact point, not individual shots. Let the barrel cool between groups to avoid heat-induced shift.
  5. Adjust the turrets precisely: Each click is 1/4 MOA. To move impact 1 inch at 100 yards, turn the turret 4 clicks in the desired direction. After adjustment, tap the turret lightly to settle the mechanism, then fire another three-shot group to confirm. Record your final zero settings (e.g., elevation 12 clicks up from bottom) in case you need to reset in the field.
  6. Set parallax for your hunting distance: Turn the side-focus knob until the target image is sharp and the reticle stops moving when you move your head slightly. For most hunting, set it to 100-150 yards; for longer shots, adjust to the actual distance. Parallax error is most noticeable at high magnification and close distances—always recheck after changing magnification.
  7. Verify with the ASV Ret 93 reticle: At 16x, use the holdover marks below the center for longer distances. Confirm the exact holdover values by shooting at 200, 300, and 400 yards, or use a ballistic calculator matched to your load. The reticle is in the second focal plane, so holdovers are only valid at the calibrated magnification (usually 16x). If you shoot at a different magnification, either dial the turrets or return to 16x for holdover.
