How to Choose the Best Weapon Light for AR15

A weapon flashlight should have different capabilities as ordinary flashlights. It is a device that you are going to mount on your firearm. Therefore, it should be able to keep up with your pace and can survive any terrains that you are going to subject it. But of course, it is not only about the construction alone. Here are some of the other factors that you should consider whenever you are choosing for a tactical or weapon flashlight.

Immunity Against Recoils

One of the essential features that a weapon flashlight should have is its immunity against recoil. Specifically, we are talking about the stability of the torch during each fire you take. You don't want the flashlight to wobble or move every time you are shooting your gun.

The flashlight itself should be able to sustain the shock. Its internal components should remain intact even in the surge of impact or energy. Otherwise, it will become destroyed quickly. Of course, always take into account the mounting system of the flashlight. You should make sure that they are reliable and rugged. The screws should fit in without any problems. In this way, you can ensure that the flashlight won't be knocked off from time to time.


You can measure the intensity of light in lumens. The higher the lumen-rating, the brighter the flashlight is. If you are going to use the torch for spotting, then there is no need for you to choose a unit that can produce extremely bright illumination. In this kind of application, you are going to use the flashlight to sight the target, and not illuminate it at all. Of course, on the other hand, the light will undoubtedly divulge your position.

A good weapon flashlight can produce light that ranges from 90 to 500 lumens. The one with the lowest rating is great for sighting. Meanwhile, the highest score can be versatile, depending on the features and modes that it has.

The flashlight should come with other functions as well to aid you in the field. For example, the inclusion of lasers would undoubtedly help, as you don't have to use the flashlight to sight at all. Moreover, the torch should have different modes (e.g., high, low, and strobe). These particular settings will allow you to use the device appropriately. You will need the strobe function if you are looking for someone or giving off some signals. That is highly necessary during rescue operations.

The interface of the flashlight should also be one of the considerations included. Make sure that the switch is in a position that it is easily accessible and non-obtrusive. As long as it simplifies the operation of the device, this particular feature is excellent.

Comfort Level

Lastly, you should choose a flashlight that is exceptionally comfortable to use. Even if the flashlight mounts on your AR15 rifle, it should not add too much weight and load. It should not make you feel awkward at all. If the flashlight somehow affects your form or view to the field, then it might not be the right option for you. Just pick an option that will never deter your speed and accuracy in sighting.

Final Verdict

The AR15 rifle is a versatile firearm. It is compatible with various gun accessories such as scopes and reflex sights. If your intended application requires you to go out in the dark, then you should install a weapon flashlight on it.

All of the options that I featured here are great for your favorite AR15. They have excellent and seamless lighting capabilities that will never leave you blind at all. But among them, you should consider the Streamlight 69260 TLR-1 first. For me, it is the best weapon light for AR15. I have already highlighted the reasons for this, but let me reiterate for you.

First, the flashlight has an incredible ruggedness. It can withstand high recoils like they never really happened. It can survive any weather conditions without any damages on its circuitries or physical components. Furthermore, it has excellent functionality and interface; using it is not a problem at all. Of course, the brightness that it has is more than enough to illuminate your way!
