Riflescope or red dot?

In today's article, we will explore the question of whether a scope or a red dot sight is better for your AR15. Many people are often unsure about the purpose of these optical devices and what their advantages and disadvantages are. They often simply follow what others use, assuming it will work for them as well. However, they may later find out that it doesn't suit them at all.

When discussing dynamic shooting, whether in sports like IPSC or in tactical scenarios, it's important to ask a few key questions. What distances will I be shooting at? If you will be shooting 90% of the time at short ranges of 25 – 50 meters, or even 100 – 150 meters, a red dot sight would be more advantageous. For mid-range distances, you can use a magnifier with 3x or greater magnification, such as 6x. A red dot sight can even be effective at distances of up to 300 meters. However, if you consider both speed and accuracy, a red dot sight is more beneficial at these short distances. Your rifle will be significantly lighter compared to one with a scope, making it easier to handle, and most importantly, you will have an unrestricted field of view.

A scope gains an advantage if you regularly shoot at distances over 150 meters, where you need to account for bullet drop, for example at 300 meters. You might think that shooters use LPVO (Low Power Variable Optic) scopes, and with a 1-6x or 1-8x scope, it's not an issue to shoot at shorter distances. While this is possible, it will likely slow you down. With a scope, the rifle is heavier, and even at 1x magnification, you must look directly through the scope to maintain your sight picture. A red dot sight, on the other hand, is more forgiving.

You often see scopes with a side-mounted red dot sight. This red dot is usually used for short distances, while the scope is for longer distances. Personally, I use a scope 99% of the time, even at short distances. The only exceptions are situations where I need to shoot a target at 10 meters and then quickly transition to a target at 250 – 300 meters. In these cases, there's no time to change the magnification, so it's essential to use both a red dot and a scope.

When mounting a scope on an AR15, remember to use a cantilever mount. This type of mount has a specified height and is offset forward by two inches, ensuring proper eye relief and preventing the scope from being mounted on the handguard, which could affect the rifle's accuracy.

On my rifle, I have the Vector Continental 1-8x24i Fiber scope, which at 1x magnification functions almost like a red dot. The dot is bright enough even in daylight. On the side mount, I use the Vector Frenzy MRS Solar red dot sight, which allows changing the reticle, although I only use the dot. It also has solar power, so it can still function even if the battery is depleted.

If you're considering a red dot sight, which I recommend to most customers, especially those who shoot at shorter distances and don't participate in major competitions, I can suggest the Vector Frenzy Plus 1x31x26 or Vector Scrapper 1x20 Micro red dot sights.
