“Zero stop” is often advertised as a major feature on many types of optics, especially with LPVOs and longer-range rifle optics. It’s often mentioned in connection with premium optics and tactical use, but what exactly is it? Is it something you need, or just a nice-to-have? 

And what kinds of rifle scopes benefit most from it?

We are breaking down the zero-stop feature in simple and clear terms, what it means, how it works, where it shines, and some instances where you might not even need it. 

We’ll also look at how zero-stop applies to different optic types (such as LPVOs, MPVOs, and HPVOs).

What is a Zero-Stop function?

Zero-stop is a mechanical feature that is built into a rifle scope’s elevation and windage turret. It allows you to return your turret to your original zero setting, typically at 100 yards, without going below that mark. It “stops” you at zero.

The zero stop feature comes in handy when you’ve dialed the turret for longer-range shots and want to quickly return to your base zero without having to count clicks or worry about going too far and messing up your next shot.

Why Is It Called “Zero-Stop”?

The term “zero-stop” is literal: it’s a stop at zero. Before zero-stop was common, shooters had to keep track of turret rotations manually. 

That left shooters at a disadvantage in high-stress or low-light situations: the lack of a zero-stop meant it was easy to dial too far and accidentally overshoot their original zero. 

The zero-stop mechanism was developed to fix that problem by providing a physical, reliable stop at the zero point.

How Does Zero-Stop Work?

There are overall patterns to how a zero-stop function works, but zero-stop systems typically vary slightly from brand to brand. Here’s how it generally works:

1. You start by zeroing your rifle, usually at 100 yards.
2. You reset the elevation turret to align the “zero” on the turret with that sight-in point.
3. You engage the zero-stop mechanism, which could be a ring, clutch, or shim system that prevents the turret from turning below that setting.
4. You dial up for longer-range shots as needed.
5. You dial back down until the turret hits the stop, and bam, you’re back at your zero.

How a Zero-Stop Function Makes a Difference in Shooting

Having a zero-stop is a great advantage, and it clearly impacts the speed and accuracy of your shooting in both a practical and psychological way. 

In fact, if you shoot at various distances and often dial your elevation turret, a zero-stop becomes more than a convenience; it’s a performance advantage

With a zero-stop function, you are:

• Confident: You know you’re always returning to the exact same zero.
• Faster: No second-guessing turret rotations—just spin it down till it stops.
• Accurate: It prevents over-travel, which can throw off your next shot.
• Stress-proof: Especially helpful in hunting or tactical situations when time matters.

Is Zero-Stop Always Necessary?

As useful and practical as a zero-stop function is, it is not a must-have in all cases.

In other words, there are shooting scenarios where you absolutely need a zero-stop function, and there are other shooting scenarios where you can do without one: it depends on how you use your optic.

• For long-range precision shooting: Yes, it’s highly recommended. You’ll be dialing constantly, and a zero-stop saves time and mistakes.
• For tactical/competition shooters (like PRS): Yes. Quick turret adjustments and fast resets are part of the game.
• For hunters: If you hunt across varied terrain and engage targets at different distances, zero-stop is a strong asset.
• For casual or short-range shooters: Probably not. If you never touch your turret after zeroing, then zero-stop doesn’t add much for you.
• For AR-15 owners with LPVOs: It depends. Let’s explore that next.

Is Zero-Stop Important in All Scope Types?

First, let's establish this: a zero-stop feature is a premium feature, and if you can get it on your optic, the better off you are. 

That being said, different optics are used for different purposes, and a zero-stop feature is less “important” in some optics than in others. 

LPVO (Low Power Variable Optic – 1–6x, 1–10x, etc.)

• LPVOs are often used for close-to-mid-range shooting.
• Many shooters use reticle holdovers, not turret dialing, so a zero-stop isn’t always necessary.
• But if you use your LPVO in a DMR (Designated Marksman Rifle) setup and engage targets out to 400–600 yards, dialing is more common, and so a zero-stop adds real value in those situations.

MPVO (Mid Power Variable Optic – 3–15x, 2.5–20x)

• These optics bridge the gap between LPVOs and long-range optics.
• You’ll dial more here, especially in hunting or tactical shooting, so zero-stop becomes much more relevant.

HPVO (High Power Variable Optic – 5–25x, 6–36x, etc.)

• Used for long-range and extreme-range precision.
• Zero-stop is essential. You’re dialing for elevation constantly, and you need to trust your turrets.

Other Features That Matter in a Zero-Stop Optic

If you’re shopping for a zero-stop optic, don’t stop (pun intended) at the zero-stop feature. Here are other things to look for:

• Turret Tracking Accuracy: The turret must dial true and return precisely to zero.
• Audible, Tactile Clicks: You want to feel and hear each click, especially under stress.
• Tool-less Zeroing: Makes setup easier in the field.
• Good Glass Clarity: Poor optics defeat the purpose of long-range shooting.
• Solid Construction: The zero-stop mechanism should hold up to recoil and weather.
• Reticle Design: BDC, MIL, or MOA reticles help you hold over or dial with confidence.
• Internal Elevation Range: A wider adjustment range gives you more long-range capability.

Final Words on Zero-Stop

Zero-stop isn’t just a buzzword: it’s a practical, performance-enhancing feature for shooters who dial their scopes regularly. 

Whether you're a long-range shooter, a competition shooter, or a hunter who engages at multiple distances, having a zero-stop makes dialing easier, faster, and mistake-free.

It might not be a must-have for everyone, especially those who rarely touch their elevation turrets. But if you value reliability, confidence, and speed in your shooting setup, zero-stop is one of those features that pays dividends over time.

So if you want a versatile, zero-stop-capable optic with premium features at a fair price, Gunnr’s Odin LPVO should absolutely be on your radar.
