Lightweight, Compact Design

A heavy AR15 flashlight is not the best companion because it adds to the burden of holding the firearm. No one wants a heavy accessory that will only cause trouble.

Battery

Ultimately, you just need to ensure that you have a flashlight with adequate battery power that will last many hours.

Certainly, you don’t want your flashlight to run out of illumination at a bad time, right? So, pay attention to this buying factor as well. 

Brightness

Undeniably, brightness is one of the most automatic buying factors when deciding which AR15 flashlight is best to buy.

While weak flashlights might sound like a bad thing, they are not.

Durability and Strength

For AR15 flashlights, durability is crucial if you don’t want to be left alone in the dark because of a broken flashlight.

Simply put, what you need is an AR15 flashlight that is light yet made from durable, strong, and weather-resistant materials. 

Aluminum is one of the ideal materials for flashlights that are best for weapons. Besides being strong and durable, it is also typically water and corrosion-proof. Thus, there is no wonder why it is an in-demand material. Another great material is polymer, which is lighter than aluminum but less durable. Choose based on your needs and preferences. 

Versatility

You will feel to have more in return if you will choose an AR15 flashlight with impressive flexibility. You will know if your choice is flexible when it features an adjustable beam and brightness. That way, you know that you can utilize it in various conditions and situations. For instance, the concentrated, bright beam can blind an attacker, while the dimmer beam helps scan the area.

Fortunately, the best AR15 flashlights on the list above score high in terms of flexibility. So, don’t feel hesitant to choose from them. 

Budget

Having a budget will help you not to spend too much. While many best AR15 flashlights are tempting to have, it is not practical to buy what you don’t need.
