A flashlight on your rifle allows you to see clearly in low light conditions, thus giving you an opportunity to identify potential hazards.

Features to look for a tactical flashlight for your AR15

If you are going to use a flashlight for defense purposes, it’s important that you buy one that you can depend on in the toughest situations.

That said, refrain from buying the first AR-15 flashlight you see at the firearm accessory store. Some of the things to look for in a tactical flashlight include:

Flashlight material

There are variety of materials used in the manufacture of tactical flashlights including aluminum, anodized aluminum and plastic. While plastic may work well, it’s best to choose an aluminum or anodized aluminum flashlight.

Both are lighter and more durable, with the main difference between the two being that anodized aluminum has an extra layer of aluminum oxide. The coating allows for increased resistance to scrapes and tears.


Since an AR-15 rifle is designed to be lightweight, the last thing you need is a flashlight that adds excessive weight. Many flashlights weigh 5-10 ounces, but there are a few good ones that weigh 4 ounces.


Ensure that your flashlight has an on/off button that works well and that it is easy to operate.

Lumens (brightness)

This is the measure of how bright a beam is. For close range tactical situations, consider a flashlight that emits 300-600 lumens. Keep in mind that the high number of lumens, the brighter a flashlight is.

Best AR-15 flashlights: Our Top Picks

1. 4Sevens Maelstrom X10 Tactical Flashlight

Image of 4Sevens Malstrom FlashlightThe Maelstrom X10 is a high quality tactical flashlight that offers two light settings i.e. full power and 100 lumens. Depending on the light setting, the battery can last 1.8-15 hours.

It emits up to 640 lumens of light, which is more than enough for combat situations in the dark. We love the instant-on pressure sensitive tail as it eliminates the need to fumble in the dark looking for the on/off button. Its head is on the larger side of what we see on LED flashlights and the smooth reflector gives it a tightly defined hotspot.

The Maelstrom X10 is powered by a specially designed 26650 lithium-ion battery. Its hard and durable shell is made from an anti-reflecting material. Our only concern is that the battery for this flashlight is sold separately. Otherwise, you get a lot of bang for your buck.

2. JetBeam Jet 3M Pro Military Series

Its programmable mode is one of the main highlights of this flashlight. The light cycles from slow to rapid probe or high to low beam when you active this mode.

You can use the button at the back to choose your preferred strobe or intensity setting. Like the Maelstrom X10, this one offers two light settings i.e. 1100 lumens and 1 lumen low-beam. The battery can last for 0.6 hours to 280 hours depending on the light settings used.

We love the sleek body as it fits in a 1” ring, has a stainless steel bezel and is waterproof for up to two meters. It only weighs 5.5 ounces so you don’t have to worry about it throwing your gun off balance.

3. SureFire X300

The light is focused by high a Total Internal Reflection lens that offers significant surround light needed for peripheral vision in close combat situations.

This flashlight is powered by two 123A batteries with a tactical runtime of 1.5 hours. It fastens easily to the firearm and the controls are easily accessible at the back, which is convenient in high stress situations.

You have the option of choosing between a Rail Lock or T-Slot mounting system when ordering the X30. This makes it virtually any type of rail system that your firearm has.

4. Inforce WMLX Multifunction LED Light

It only weighs 4 ounces, which is as good as you can get. The flashlight is powered by two lithium ion batteries with a tactical lifetime of two hours.

We love that it offers three light settings, which is an improvement from the two light settings provided by other models. These include full beam, strobe light and momentary flash light.

It has a heavy-duty shell that is built to survive rigorous use. The pressure sensitive switch at the back of the light makes it easy to turn on and off without having to fumble in the dark.

5. Klarus XT30R Long Distance Illuminator

The XT30R from Klarus will prove a worthy investment if you are in the market for a flashlight that provides intense light. This flashlight offers five light settings i.e. full power, 400 lumens, 20 lumens, strobe light and 100 lumens.

The battery can last for 2.5 hours to 75 hours depending on the preferred light setting. We love the aircraft-grade aluminum body as it is a guarantee that the flashlight will last through the toughest situations.

Our only concern is that it weighs slightly less than ten ounces, making it the heaviest flashlight on this list.


Having learned a little about tactical flashlights, you can embark on your search for a weapon-mounting flashlight for use with your AR-15 rifle. Trying a few models makes it easier to find something that works best for you.
