How To Choose AR 15 Rifle Scope?

Choosing a good AR 15 Rifle Scope is rather a difficult job. One must never hurry or spend thousands of monies while purchasing a rifle scope. If you are planning to buy a scope, you must keep in mind the key points. A few essentials are as follows:


One of the essential points is to keep in mind the brand. Do not buy any random or cheapest product for the sake of having a rifle scope. You can find the high – quality scopes within the range of $ 800 to $ 1200. However, if you are a beginner, you can start with a comparatively low-budget. 

Caliber / Chambers

Next, we have to keep in mind the caliber and the chambers. A rifle scope must have a chamber for 5.56 mm instead of a .223 Remington. Although both the cartridges are dimensionally similar, they are not the same. The 5.56 mm is used for slightly higher velocity and pressure. Therefore, you can safely fire a .223 Remington easily in a 5.56 mm rifle but doing the contrary can be risky and unsafe. Hence, it would help if you got a more versatile 5.56 mm chamber. However, the newer .223 Wylde chamber safely accepts both cartridges.

Barrels and Twist Rates

It would help if you always looked for short and lightest barrels for your AR 15 rifle scope. The long heavy ones are useful for extended range bench rest and match shooting, but they are not ideal for self-defense. One must get a rifle with a weight of 14.5 ” – 16 ”, or an M – 4 profile barrel with a flash suppressor. It would help if you kept in mind not getting a muzzle brake other than the flash suppressor. 

Next, the twist rate helps to determine which bullet performs the best in the rifle. If you want to shoot longer with heavier bullets, you need a fast twist rate of (1:7). However, if you’re going to shoot shorter or lighter bullets, you require 55 grain or less for better performance. In general, the 1.8 and 1.9 twist rate works fine. It would help if you also remembered to have a lined barrel, either the chrome lining or the newer Melonite or Nitride coatings. It will give you 5,000 + extra rounds fired before you start experiencing accuracy degradation.

Red Dot Optics

The red dot optic helps you to shoot way faster than open sight. The current red dots have a battery life of more than two years. Therefore, dying batteries are not an issue anymore. Moreover, if you have a red dot, you also need an iron sight as a backup in case the red dot is damaged or fails.

Magnified Optics

Most of the shooters nowadays replace the red dot with a variable power magnified scope. The power of these scopes revolves around 1x – 6x, or 1x – 8x. They can be used as the red dot at close range but give extra magnification for long distances. They are useful if you find yourself taking frequent 100 – 300 meter shots. Otherwise, the red dot is the best for speed. 


A rifle scope requires specific attributes to give the user the best experiences on their adventure expedition. Before spending money on random scopes, think about the purchase wisely. No one would want to get a poor, faulty product even if it is for their profession or as a hobby. Therefore, we hope the article was helpful to you, and now you can make your decision without any doubt. Have a happy buying.
