The Zero Stop: What It Is and Why You Need It for Precision Shooting
When it comes to long-range shooting, consistency and precision are everything. Whether you’re a competitive shooter, a hunter, or someone who loves hitting targets at various distances, you know that keeping your scope dialled in correctly is critical. That’s where a zero stop comes in.
But what exactly is a zero stop, and why should you care? Let’s dive into the mechanics and benefits of this handy feature.
What is a Zero Stop?
A zero stop is a feature built into the turrets of your rifle scope that ensures you can easily return to your zero position after making adjustments. In simpler terms, it’s a mechanical mechanism that prevents you from rotating the elevation or windage turrets past your original “zero” setting. This is especially important when you're adjusting for things like wind, bullet drop at long distances, or changing shooting positions. The zero stop gives you the peace of mind that you can always return to your baseline, zeroed-in point.

How Does a Zero Stop Work?
To understand how a zero stop works, let's break it down:
-
Scope Turrets and Adjustments: Your rifle’s scope has two primary turrets—elevation (up/down adjustments) and windage (left/right adjustments). These are rotated to change the position of the reticle, which alters where the bullet impacts the target. When you adjust your turrets for shooting at different distances, you’re compensating for factors like gravity (which causes bullet drop), wind, and other variables.
-
The Need for a Zero: After making these adjustments, you'll likely need to return to your original zero position when shooting at a known distance (say, 100 yards). Without a zero stop, you would have to rely on markings or guesswork, which can lead to missed shots if you're not careful. This is where the zero stop mechanism ensures that you can return to that starting point quickly and accurately.
-
Physical Stop: The zero stop mechanism physically prevents the turret from turning beyond the zero position. It may be an external collar, an internal mechanical stop, or even a shim system. This stop guarantees that once you return to zero, the scope won’t rotate past that point, ensuring consistency and accuracy.
Types of Zero Stops
There are a few different types of zero stops, each with its own design and benefits:
- External Zero Stop:
- This is typically a collar or external mechanism placed around the turret. When you adjust the turret and reach the zero position, the collar stops further rotation, ensuring that you don’t accidentally go past zero.
- Internal Zero Stop:
- This type of zero stop is built inside the turret mechanism. The scope’s internal gears or a spring-loaded mechanism will prevent the turret from turning past zero. These are often more precise but harder to adjust on the fly compared to external designs.
- Shims or Spacers:
- Some zero stop systems use spacers or shims inside the turret assembly to create a physical block that halts the turret's movement at the zero point. While these are less adjustable, they offer a reliable solution for ensuring a consistent return to zero.
Why Should You Care About a Zero Stop?
A zero stop isn’t just a luxury feature—it’s an essential tool for precision and repeatability. Here’s why:
-
Quick Return to Zero: Whether you’re shooting long-range or adjusting for wind, the zero stop ensures that after dialing the scope for adjustments, you can quickly return to your original zero position without second-guessing your settings. This is especially useful when switching between varying distances during a hunting trip or competition.
-
Consistency and Accuracy: When you need to make repeated adjustments, such as when shooting at different ranges, a zero stop helps keep everything consistent. If you’re using a scope without a zero stop, it’s easy to accidentally overshoot the zero position, which could lead to inaccurate shots. The zero stop eliminates that risk, making your shooting process much more predictable.
-
Confidence in the Field: For shooters in the field—whether you're hunting or in a tactical scenario—there’s no room for error. The zero stop lets you focus on the shot rather than worrying about whether you’ve dialed your scope back to zero correctly. This extra level of certainty can make all the difference in hitting your target when it matters most.
-
Convenience: If you frequently adjust your scope for different environmental factors (like wind or range), the zero stop can save you time. Instead of having to carefully check and adjust your turrets every time you change settings, the zero stop lets you focus on making quick, precise shots.

Practical Applications of a Zero Stop
A zero stop is more than just a handy feature—it has real-world applications for any shooter who needs precision:
-
Long-Range Shooting: When shooting at extended distances, you often need to dial in for bullet drop. The zero stop allows you to return to your original zero after making those adjustments, so you can confidently take your next shot without worrying about whether the scope is properly set.
-
Hunting: In hunting, you may find yourself adjusting the scope depending on your target’s distance. The zero stop makes it easy to quickly get back to your starting zero setting, ensuring you’re always ready for that perfect shot, regardless of how much you’ve adjusted your scope.
-
Competition Shooting: Shooters in competitions often engage targets at various ranges. A zero stop ensures that after each adjustment, you can return to your starting point and take your next shot with precision, making it an invaluable tool for competitive scenarios.
-
Environmental Adjustments: When you adjust your scope to account for environmental factors (like wind or temperature), a zero stop ensures that once those factors change, you can easily return to your original settings.

Setting Up a Zero Stop
Setting up a zero stop can vary depending on the design of your scope, but here’s a basic rundown of the process:
-
Dial to Zero: Start by adjusting the turret to your known zero setting (the distance at which your rifle is zeroed, like 100 yards).
-
Adjust the Zero Stop: Once you’re at zero, adjust the zero stop mechanism to ensure it prevents further rotation. For external zero stops, this may involve tightening a collar. For internal stops, you may need to adjust a set screw or shim.
-
Test Your Settings: After adjusting the stop, it’s a good idea to rotate the turret a few times to ensure it stops at the zero position consistently. This will verify that your zero stop is functioning as intended.
The Bottom Line
Whether you’re shooting at a range, out in the field hunting, or participating in a competitive event, a zero stop is an invaluable tool that ensures you maintain accuracy and consistency in your shots. It removes the guesswork from dialing your scope back to zero after making adjustments, giving you confidence in your rifle setup every time you pull the trigger. If you’re looking for repeatable precision, investing in a scope with a zero stop could be one of the best decisions you make
