Using an AR-15 for defensive or tactical purposes pretty much requires a weapon mounted light.
You need to see what you’re shooting at. And you need to be able to operate your AR-15 with both hands, whether you’re using your light or not.
A weapon mounted light is just about the only way to meet these two requirements. Unfortunately, lights designed specifically for weapon-mounted use can be rather pricey.
But you can use a standard tactical flashlight and mount it to your rifle using a flashlight mount, which can save you a bit of money and enable you to use your favorite flashlight as a weapon light, even if your favorite light isn’t specifically a weapon-mounted light.
If you go this route, you need a good flashlight mount.
SPOILER—need to know the best AR-15 flashlight mount quick, fast, and in a hurry? Get the Viking Tactics Light Mount. It’s well-priced and durable. And it works on most handguards.
If you need something a bit more specific and want to look around, we’ll shed some light on the best AR-15 flashlight mounts.

Scroll based on your budget.
1. Viking Tactics Light Mount - Overall Best AR-15 Flashlight Mount
The Viking Tactics Light Mount is simple and effective, which is always a good thing from any piece of gear.
This flashlight mount attaches to a picatinny rail, which most handguards have at the 12 o’clock position. So it will fit where you need it on almost any handguard.
The mounting system puts your light at about the 11 or 1 o’clock position, which I find to be the best positions for a light.
This position makes it easy to actuate your light with your thumb without shifting your grip very much, if at all. And it works just fine if you have a remote switch.
This flashlight mount is compatible with flashlights that have a .80 or 1 inch diameter. That covers a broad spectrum of lights from various manufacturers.
However, the footprint is fairly wide. It’s about 1.5 inches long. So you won’t be able to use any super compact flashlights.
Lastly, this flashlight mount is made of thermoplastic, which is similar to the polymer used in pistol grips and stocks. It’s plenty durable. And, if you prefer metal, there are options for that, which we’ll get to.
But, if you want an affordable flashlight mount that will work with a lot of flashlights, this one fits the bill.
2. Magpul M-LOK Offset Light/Optic Mount - M-LOK AR 15 Flashlight Mount
The Magpul M-LOK Offset Light/Optic Mount is an ideal mounting solution for anyone who has an all M-LOK handguard with no picatinny rails.
It’s an angled mount that places your flashlight at the 11 or 1 o’clock position. It’s perfect for using your light without shifting your grip. All you have to do is move your thumb.
Also, this flashlight mount is aluminum. Most people probably wouldn’t notice the difference between a polymer mount and an aluminum mount. But aluminum is more durable than polymer, regardless of whether or not the average user needs all that durability.
Lastly, this mount gives you a section of picatinny rail to mount your light to. It’s not ideal if you want to use a handheld light as a mounted light. But it’s perfect for attaching a light to an M-LOK handguard, since most lights come with a picatinny rail mount.
So, if you have an M-LOK handguard, and not a lot of picatinny rail space, this Magpul flashlight mount will solve your rail space problems.
3. Bravo Company Ring Light Mount - KeyMod AR 15 Flashlight Mount
The Bravo Company Ring Light Mount is what you need if you have a KeyMod rail and a flashlight that you want to attach to that rail. If you have a light with a picatinny rail mount, you can use the Bravo Company 1913 Modular Light Mount.
Like most things that Bravo Company makes, this flashlight mount is made of metal—specifically, aluminum. So it’s just as durable as an aluminum handguard.
It fits any flashlight with a 1 inch body tube. This offers a lot of light compatibility.
However, it’s a 2-ring mount, which means it’s not ideal for use with very compact flashlights.
But it puts your light at the 9:30 or 1:30 position. These are two of the best places to put a light on an AR-15, since you won’t have to shift your grip to use your light. And it works fine if you want to use a remote switch.
Overall, this Bravo Company flashlight mount is excellent that gives you a strong attachment point for your KeyMod handguard.
4. Arisaka Ring Light Mount M-LOK - Compact AR 15 Flashlight Mount
The Arisaka Ring Light Mount (also available for in KeyMod) enables you to mount a handheld flashlight to your AR-15. And it’s compatible with more lights than most flashlight mounts.
First, this flashlight mount is constructed from 6061 aluminum, which is just as durable as most handguards. This flashlight mount won’t be the achilles heel of your rifle.
Also, this mount comes with 2 rings: one for .84 to .88 diameter flashlights, and one for 1 inch to 1.03 inch diameter flashlights.
And it’s a single ring mounting system. So you can use compact flashlights with this mount, too. In short, this flashlight mount will accept almost any flashlight.
However, even though it holds your flashlight remarkably securely, it’s possible that your light could slide forward or back in the single ring with enough impact.
Now, I’ve never actually seen a flashlight slip in the ring. But I’ve also never rammed my flashlight against stuff to test it.
In other news, this mount places your flashlight at the 11 or 1 o’clock position, which is one of the best places to put your light.
And this Arisaka mount is very low profile. It fits almost anywhere on any handguard.
Overall, this is probably the most versatile flashlight mount you can get. It’s very durable. And it’s thoughtfully designed to give you the most light compatibility and mounting options.
5. Haley Strategic Partners Thorntail SBR Offset Adaptive Light Mount - AR 15 Flashlight Mount for SBR
The Haley Strategic Partners Thorntail SBR Offset Adaptive Light Mount is designed specifically to deal with the space restrictions of short-barreled rifles, where rail space comes at a premium.
This flashlight mount is an aluminum mount that attaches to a picatinny rail. Most handguards have a picatinny rail at the 12 o’clock position. And picatinny rail sections can be added to almost any handguard. So this mount offers a lot of rail compatibility.
However, this flashlight mount is designed to keep your light slightly further back. That way your lens doesn’t get blasted by the muzzle blast of your SBR. It helps keep your lens clear and extends the life of your flashlight.
Also, offers 8 different mounting solutions. This flashlight mount is compatible with almost any flashlight.
If you attach this mount to the top rail of your handguard, it puts your flashlight at about the 11 or 1 o’clock position. So you can reach your flashlight without compromising your weak hand shooting grip.
It’s not the most affordable flashlight mount on the market. But you can use this Haley Strategic Partners accessory to mount almost any light. And it helps protect your light from your SBR and keep your rail clear for other accessories.
Light it Up!
Purpose-built weapon-mounted lights can be expensive. And, often, the included mounting system with a light won’t work all that well on your handguard.
A good AR-15 flashlight mount gives you a lot more flashlight and mounting options. And can make it possible to put your flashlight in the best spot on your rifle, where an included mount may not do that.
If you’re struggling with your light and need a flashlight mount that will help you solve your problems, get the Viking Tactics Light Mount. It’s a simple, but versatile flashlight mount that’s very reasonably priced.
Now that you know, it’s time to give up those awkward one-handed rifle manipulations. Get a flashlight mount and put your weapon-mounted light where it belongs: on your rifle. And that's definitely a sound investment.
