It comes to a tightened interface design that prevents your hands from touching the muzzle whenever you are installing or detaching it.

Moreover, it is also notable that the Streamlight 69260 TLR-1 is an extremely rigid flashlight. It is crafted from machined aircraft aluminum and has received anodized finishing. Meanwhile, the glass of the torch has high-temperature resistance and impervious to shock.

The device has a lithium-ion battery. It can run for 2 hours straight if cranked to its maximum capacity. Overall, the battery lifetime of this flashlight is around 50,000 hours. It can generate up to 800 lumens of brightness, which is enough to provide seamless vision to the field.

The SureFire X300 is a great contender when it comes to the best tactical flashlights. It is a high-performance LED flashlight that is capable of producing up to 600 lumens of brightness. The light that it produces tends to favor the yellow-to-green spectrum because the human eyes see these colors much better than white light.

This flashlight is using a TIR lens that generates a small and smooth beam, which improves its peripheral illumination. The glass itself is durable and seamless, not allowing external detriments to pass through it. On the other hand, the placement and operation of its switch are ambidextrous. You can use the switch to just one finger only.

Also, take note that the SureFire X300 has an optimized rail-lock system. This component enables you to secure and tighten the flashlight on any weapon. You can guarantee that you can mount this one to both Picatinny and Weaver rails. The torch is compatible with pressure-activated switches, too. The latter is just an optional feature, but it can remove the need for you to alter your grip to the firearm. As a result, you shot become stable.

A budget-friendly LED flashlight for your AR15 is not a far-fetched dream. There are several options that you can try out there but among them. The Monstrum Tactical may come at the top. This entry-level LED flashlight is capable of generating 90 lumens light. Although it is not as bright as the other flashlights that I featured here, such capability is pretty decent already.

Just like the first two weapon flashlights that I have featured, the Monstrum Tactical has a built-in rail mount. It can perfectly fit with Picatinny and Weaver rails. Installing it to your firearm is not problematic, either. It is compatible with most standard rifles, shotguns, and handguns on the market today.

One of the most significant selling points of the Monstrum Tactical is its compact design. With a length of only 3.7 inches, the Monstrum Tactical is among the smallest weapon flashlights that currently exist. It is also extremely light (only weighs around 2.5 ounces). But of course, I can still guarantee that this flashlight is rugged. After all, the body of this device comes from aircraft-grade aluminum.

I can say that the Orion H40-W Tactical Flashlight is designed to survive extreme terrains. The body has an aerospace aluminum with hard anodized finish. Furthermore, this flashlight is impervious to the effects of gun recoil, due to the presence of a rugged LED emitter. The torch has an IPX-7 rating, which means that you can expose it to rainy conditions and submerged it to shallow waters.

The Orion H40-W Tactical Flashlight features a hardened glass lens to protect the internal circuitries of the device. There is an aluminum reflector integrated on this flashlight that enhances the distance and quality of the beam. Accurately, it can throw light up to 175 yards (or 160 meters). It gives you the visibility advantage as you can see your targets way before they can spot you.

    Has a long operating time, even if cranked at to maximum output
  • Surprisingly light and compact construction
  • Waterproof and can be submerged into water
  • Compatible with various mounts
  • None of its parts have cheap construction

Another tactical flashlight from Streamlight that you should consider is the Streamlight PolyTac. Just like the rest of the torches here, this one has an excellent construction and design. It is compatible with AR rifles and other types of guns, too. However, the main selling point of this device is its operating time. This one can run up to 3 hours straight. That is three times longer than most of its competitors.

The push-button of the Streamlight PolyTac is capable of constant or momentary operation. These two functions enhance the flexibility of the device. When it comes to its light production, this flashlight is impressive as well. Correctly, it can produce up 275 lumens of brightness. The C4 LED light of this torch has a parabolic reflector that improves the peripheral illumination.

Aside from its aircraft-grade aluminum construction, the body of this flashlight comes with nylon texture. Therefore, its durability is unquestionable at this point.

How to Choose the Best Weapon Light for AR15

Best Weapon Light for AR15 (1)

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.

Brightness

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.

Ergonomics

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!
