Some come with rechargeable batteries, which provide great value for your money since they are more expensive. On the other hand, others only have disposable batteries. The primary flaw is that you might need to carry additional batteries, which can be troublesome. 

Whichever kind of battery it is, they all have their fair share of flaws. That said, there is no right or wrong when choosing the battery. Everything goes down to your preference.

On the flip side, you can select a more powerful flashlight if you need one that you will use outdoors. Powerful ones are suitable for an environment where you can only have the flashlight as the light source.

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. You want to ensure that even if you have lightweight AR lights, they will last even in tough situations. 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. 


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. 

At the same time, it is also more practical to choose an AR15 flashlight with ambidextrous controls. Because of that, you won’t worry about any hands you use to control, operate, or adjust the grip. Fortunately, the best AR15 flashlights on the list above score high in terms of flexibility. So, don’t feel hesitant to choose from them. 


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. So, be sure to have a budget to narrow your choice without feeling overwhelmed. Anyway, you can always go a little over your budget if you have already discovered the best AR15 flashlight suited for you.
