Evelyn: hi stephen, when purchasing riflescopes, i've been hearing a lot about zero stop and zero reset. Im quite confused, can you explain what these terms mean?
Stephen: sure, evelyn. Zero stop and zero reset are two important features in riflescope adjustments. Before we talk about them, i have a question for you, do you know how do shooters zero their scopes normally?
Evelyn: yes, when a shooter zeroes their scope, they are aligning the reticle with the point of impact for a specific distance. Under normal circumstances, the shooter would then make adjustments to the scope to account for changes in distance or other factors. Check out picture 1 for reference.
Stephen: yes, and a zero stop for scopes is a feature that allows the shooter to quickly return the scope to its original zero point without having to make any adjustment.
Evelyn: i see. And how to achieve zero stop?
Stephen: the process varies depending on the brand and model of the riflescope. First, the shooter needs to determine the zero point by shooting at a target at a known distance and making adjustments until the point of impact(poi) matches the point of aim(poa). Once the zero point is established, the shooter can set the zero stop mechanism to prevent dialing below the zero point. Here we take two turret caps from vector optics as an example.
1. Release the 3 screws on the elevation turret and remove the cap.
2. Release the 3 screws of the internal plate.
3. Following the internal plates direction and rotate it to the end
4. Tighten the internal 3 screws
5. Cover the cap at 0 position, tighten the 3 screws
1. Aim your target and zero the scope
2. Use the plastic wrench to release and remove the top screw.
3. Take off the turret cap
4. Rotate the inner ring clockwise until it stops
5. Tighten the cap
Evelyn: i see. And what about zero reset?
Stephen: zero reset is a mechanism that allows the shooter to reset the turret to the zero point after making adjustments for elevation and windage.
Evelyn: and how to achieve it?
Stephen: to use zero reset, the shooter needs to unscrew the turret cap and adjust the turret to zero, then reattach the cap and tighten it securely. Here we take vector optics marksman series scope as an example.
1. Loosen the center screw with the wrench and take it off.
2. Take off the turret cap.
3. Align the mark 0 on the turret cap with the click marker on the scope.
4. Tighten the center screw with the wrench; done.
Evelyn: that makes sense. And how to choose between zero stop and zero reset?
Stephen: the choice between zero stop and zero reset comes down to personal preference and use case. Zero stop allows for quick return to zero but has limited range of adjustments, while zero reset provides a reliable reference point but can be time-consuming when resetting turret.
Evelyn: i see. So for long-range precision shooting, zero stop may be preferred for its added accuracy, while zero reset may be more useful for hunting or tactical applications where quick adjustments are needed. Am i correct?
Stephen: yes, thats right!
Evelyn: great! Ive learned a lot today! I cant wait to share what i learned with you all, check out picture 5 for a brief summary!
