4 MOA Vs 2 MOA : Head To Head Comparison Between Them

Shooting at a target and then pinning it down by hitting exactly at the aiming point gives an unavoidable thrill. Such an experience never fails to amaze a shooter. But acquiring that level of shooting accuracy doesn’t come overnight.

Usually to be a great target shooter, along with great skills one needs great optics as well. In a close-range distance, Red Dot reticles are unmatched. But choosing the right one for you depends on various things.

The kinds of firearms & your regular shooting range are two of those factors that decide whether you should use a 2 MOA Red Dot or a 4 MOA Red Dot. As both of these red dots have different dot size, covering target areas at a certain distance, suitable guns etc. are very vital things too.

Therefore, while discussing their difference we have tried presenting you with an articulated 2 MOA Vs 4 MOA Red Dots review article.

What is 2 MOA Red Dot Meaning?

What is 2 MOA Red Dot Meaning

Let’s imagine a shooter has pointed his gun at a target 100 yards away from him. He is also using a red dot reticle that is mounted on his gun to have a better view at the aiming point.

Now he will see a red dot placed upon the target and he would try to shoot in such a way so that the bullet hit it on that particular spot. That red coloured dot is measured by the parameter called Minutes Of Angle (MOA).

If the Red Dot he is using is a 2 MOA then that means, the red coloured dot placed upon the target which is at 100 yards of distance has a diameter of 2 inches. This angular measurement of the circle is called 2 MOA Red Dot.

What is a 4 MOA Red Dot?

What is a 4 MOA Red Dot

MOA ( Minutes Of Angle) refers to the angular measurement of the red coloured dot that is projected on a target once it is aimed & seen through a red dot reticle.

4 MOA means the circular target area is 4 inches in diameter when the target is placed at 100 yards of distance. Basically, a 4 MOA Red Dot reticle is used for both close & long-range target shooting.

2 MOA Vs 4 MOA

There are significant differences between a 2 MOA Red Dot & a 4 MOA Red Dot. We have tried here to mention some noteworthy differences between them by plotting a table.

2 MOA Vs 4 MOA

The difference between a 2 MOA & 4 MOA Red Dot is quite vivid when the target distance and firearms on which they are being mounted becomes a factor. Some distinguishing factors are stated below- 

  • A 2 MOA Red Dot covers a target area of 2 inches on a target at 100 yards distance whereas a 4 MOA covers 4 inches target area. 
  • 2 Moa Red Dot are usually used for short-range target shooting, on the other hand 4 MOA Red Dot are used for both close & long-range shooting.
  • When it comes to perfect use, shotguns & handguns perform better with a 2 MOA Red Dot Reticle but 4 MOA Red Dot Reticles are suitable for rifles & long guns. 
  • Red Dot Reticles are normally available with no magnifier. So when used in a magnifying optic, the target area gets enlarged depending on the magnification power. For 2x magnification, the covering area becomes 4 inches for 2 MOA & 8 inches for 4 MOA at a target distance of 100 yards. 
  • If it is about acquiring more precision level then most of the shooters think a smaller red dot size like 2 MOA is more likely to provide better accuracy. But that doesn’t mean 4 MOA comes shorter at accurate shooting. But for close range shooting smaller red dots are comparatively more efficient.

What is a 2 MOA Red Dot Reticle? 

Red Dot reticles are available with so many different variations of MOA (Minutes Of Angle). A 2 MOA reticle is one of those options. Suppose,  you are aiming at a target at 100 yards of distance with your gun that has a 2 MOA Red Dot reticle on it.

That means you’d see a red dot covering a target area of 2 inches on your target. The 2 inches red circular target area on your target that is  located 100 yards away is known as 2 MOA red dot reticle.

Is 2 MOA Better Than 4 MOA?

It entirely depends on their usage and the gun you are mounting it on. Basically, the distinguishing factor establishes quite vividly when shooting at ranges come to the play.

If you are using handguns or shotguns and shooting at short-range distances, then using a 2 MOA optic would be a better choice compared to 4 MOA. But if you own a long gun or rifle & aim at long distance then 4 MOA will be a better pick in such cases.

Red Dot Sizes- Why They Differ?

The Red Dot comes with having different MOA spending on the usage and their necessity in target shooting. A smaller Red Dot covers a small target area whereas a larger Red Dot naturally covers a larger area.

Red Dot of 1 MOA will cover about 1 inch of target area at a distance of 100 yards. In a 2 MOA Red Dot, a dot size of 2 inch will appear on the target upon aiming on it. For 3 MOA & 4 MOA and so on, it follows the same rule. But it depends on the target distance too.

Red Dot Sizes- Why They Differ

Minutes Of Angle

Minutes Of Angle is actually referred to an angular measurement of a red dot circle or other optical reticles. As a bullet being a projectile & the trajectory of it is not 100% right always, the Minutes Of Angle is kind of an expression of the hitting area by a bullet. 

A Minutes Of Angle means 1/6th of one degree out of infinity that is relative to a fixed point. In other words, 1 MOA equals a dot size of roughly one inch (1.047) diameter at a distance of 100 yards.

Minutes Of Angle is actually referred to an angular measurement of a red dot circle or other optical reticles. As a bullet being a projectile & the trajectory of it is not 100% right always, the Minutes Of Angle is kind of an expression of the hitting area by a bullet. 

A Minutes Of Angle means 1/6th of one degree out of infinity that is relative to a fixed point. In other words, 1 MOA equals a dot size of roughly one inch (1.047) diameter at a distance of 100 yards.

Red Dot Priorities Straight: Speed vs. Precision

It is no rocket science to understand that speed and precision both are utterly hard to attain simultaneously in shooting. If you look for speed your precision level will drop, on the other hand if you take a shot to hit the bullseye your speed may drop too.

Therefore having a perfect optic along with a suitable gun is so important when it comes to speed & accuracy in shooting business. 

An optic helping with fast target acquisition is a very cherished thing to professional shooters. For close range shooting, a high level of accuracy can be maintained by using Red Dot reticles.

Even though Red Dot reticles have no magnifier but they come with variations like 2 MOA, 3 MOA, 4 MOA etc. For using a Red Dot reticle you have to decide your purpose first. If you seek for speed then in close range target shooting there is no equivalent to a red dot reticle.

But it also depends on the distance you are shooting at. On the other hand, maintaining a high level of precision requires skilled shooters too along with perfect red dot optic.

The more your target distance will increase, the more you will lose the precision level. Therefore, for attaining sharp accuracy at 100 yards of distance, a 2 MOA Red Dot will provide the best service.

But going much beyond that will require greater magnification and proper scope too. Although a 4 MOA Red Dot is no less than a great optic for shooting accurately at close & long range either.

Red Dot Reticles

It is a holographic projection of a dot to a fixed point in the focal plane of the lens. It is usually red in colour but sometimes can be found in green too. The size of the red dot is measured in Minutes Of Angle (MOA).

Moreover, it has been proven that the red dot happens to be the quickest sort of aiming reticle. It also gives the best target hitting probability with a high level of accuracy even for moving ones.

3 MOA Red Dot

An MOA ( Minutes Of Angle) number is a parameter that is usually listed on a red dot sight. It refers to the size of a dot that will appear on a target placed at 100 yards of distance.

As we know that 1 MOA means, 1 inch dot size at 100 yards distance, the same way a red dot of 3 MOA means there will be a 3 inches sized dot appearing on the target at a distance of 100 yards.

Aimpoint 4 MOA

Aimpoint is a Swedish optics company, globally famous for manufacturing red dot sights for the use of civilians, police and people in the army. It comes with numerous newly manufactured & featured  popular scope models.

For military operations & combat the Aimpoint Pro & other models are used by several countries. The Aimpoint 4 MOA is actually referring to the dot size of the scope that falls upon the target.

In an Aimpoint optic when the Minutes Of Angle is 4 MOA, then it means a 4” sized dot will appear on the aimed target at a distance of 100 yards.

1 MOA Red Dot 

The dot which appears in a red dot optics while sighting is measured in MOA that stands for “Minutes Of Angle”. It is a unit to measure the angle of a circle. A smaller red dot naturally covers less area of the target whereas a larger one covers a bigger area. 

However, for fast-moving targets, a larger red dot is proved to be quite advantageous for moving targets. Actually, 1 MOA means 1/60th of 1 degree angle.

Frequently Asked Questions

What is better 2 MOA or 4 MOA?

When it comes to shooting at long distances, the difference between a 2 MOA and a 4 MOA model would be quite significant. The 2 MOA dot will cover a comparatively smaller area

At a long distance of more than 300 yards, the 4 MOA dot will cover almost a foot whereas the 2 MOA would cover an area that would be smaller than your fist. 

What is the best MOA for red dot?

Usually, a smaller red dot would cover less target area compared to a larger one. On the contrary, a larger red dot would be a greater advantage in the case of a moving target

Is 3 MOA or 6 MOA better?

A 3 MOA happens to be more efficient and precise for shotguns and pistols. On the other hand, 6 MOA is suitable for rifles & long guns

As a 6 MOA provides a bigger dot size, it seems to be perfect for long-range and fast-moving targets too. Therefore, it is easier for a shooter to pin down a target with precision. 

Is a lower MOA better?

Yes, it is. The ratings of a lower MOA are more accurate than they are at long ranges. At 100 yards of distance, a scope with 3 MOA will shoot 6″ groupings.  

What does 2 MOA dot mean?

A 2 MOA dot means it will produce a dot with 2 inches of covering size on a target at 100 yards of distance.

What MOA is best for a pistol?

For the ultimate level of precision for hunting or target shooting with a pistol, a  4MOA dot or less is a good idea.  

What red dot sight does the military use?

For military missions & combat, the army uses Aimpoint Red Dot Sight

What distance do you zero a red dot?

50 yards is proper if not the best distance to set your zero for a fixed elevation rear sight or a red dot. 

Which is a better reflex or red dot?

Basically, a red dot happens to be easier and faster for target acquisition than most traditional sights. Although it is not as fast as the exposed reflex sight. Besides, Reflex sights are less expensive than red dot sights too. 

What distance are red dot sights good for? As red dots are non-magnifying optics, they are best for use at 100 yards of distance. Beyond 100 yards, the accuracy depends on the target size and design of the scope.


While target shooting precision always becomes a vital factor. If you are a hunter or a professional shooter then the importance of an efficient optic is quite a lot. Having a shot & hitting the aiming point is a great experience anyway. 

A red dot reticle makes it easier even more. Hence, purchasing the Red Dot reticle for your firearm matters so much. Hope our article will help you to have a clear idea and to take the right one according to your need.    

Good Luck!!!
