Red Dot Sights VS. Rifle Scope: What’s the Best for AR-15?

Red dot sights or rifle scope,which one is the most accurate?

Adding right optics to your AR-15 will enhance the accuracy. 

One of the most common questions is: a red dot or a magnified scope? You’ll figure it out by the end of this guide. Let’s dive in!

Why choose a red dot sight?

Red dot sight is an optic with a red (or green) laser dot in the center. They are small, lightweight so they won’t weigh down your rifle, are parallax-free, meaning that the aiming point is on target regardless of the shooter’s eye position. 


fast, and contain a glowing, are famous for their quick target acquisition and are more accurate.

The best part? You can keep both eyes open while firing since most red dot sight is without magnification, the field of view is significantly wilder than that of rifle scopes, making it perfect for short-range shooting.

Red dot sights can be adequate on rifles or short-barreled rifles up to 300 yards, but most shooters typically prefer using them within 100 yards. 

While red dot sights do not offer any magnification, they are not inferior to a rifle scope at close range, especially home defense; the red dot sight is a far more appropriate choice.


How about a rifle scope

The rifle scope is generally applied for medium to long-range shooting up to 400-500 yards since their fixed or variable magnification scopes and adjustable elevation and windage.


Rifle scopes are more versatile in targeting scenarios than red dots. They are generally more accurate than a red dot unless the target is super close, especially those with a big objective lens(50mm), offering great low-light performance, which would improve your shooting confidence.


Additionally, the reticle patterns of rifle scopes can be customized to meet different scenarios and needs. Rifle scopes with more illuminated reticles offer a wilder illumination zone than red dot sights, allowing the shooter to turn the red dot based on the lighting conditions finely.



 In other words, as long as you select the correct magnification, the rifle scope would achieve its full potential.

Finally, although rifle scope is usually for medium to long-range shooting, that doesn’t mean it can’t be used for short distances. You’ll want to select one with a good magnification range based on your plan.

In dense jungles, shooters usually only need to shoot out to 100 to 200 yards. In that case, 1-4x, 2-10x, or even 3-12x magnification will suffice. 

In the open plains or high mountains area of the west, Your shooting range will undoubtedly be much farther; a high magnification rifle scope would achieve the best effect in this case, such as 3-18x, 4-16x, 6-24x, or even 5x30.

No matter which type of sight you choose, please keep in mind that it’s not the more you zoom in, the better.

Therefore, choosing a rifle scope with correct magnification is the very first step of accurate shooting.

What if a Combination of Both?

Is there any way to combine the advantages of these two optics for any target distancing scenario? Of course! With a red dot mounted on a rifle scope, the benefits of this combo will double!

Purchase the combo of a red dot mounted on a rifle scope is affordable than getting the two separate.

Red dot sights generally fit short-range shooing(between 0-50 yards), if you need a medium-long range shooting, rifle scope designed for that(over 100+ yards). Or a super combo that combined these two!
