Why Would I Want a Flashlight Mounted to My AR-15?
Simply put, mounting a flashlight to your AR-15 or other tactical weapon is a good idea if you need a gun for home defense.
They enable you to see in low-light situations, especially indoors where night-vision or thermal optics aren’t feasible, and help give you the opportunity to safely identify potential hazards.
Never fire your gun into the dark without first identifying the target.
As you already know, it’s never okay to fire your gun without first identifying your target. That alarming sound that woke you up in the middle of the night may not be an intruder, but rather a friend, family member, or pet.
Additionally, AR-15s are easy to mod and you can find just about any aftermarket piece you could possibly want.
The real question is, “Why wouldn’t you mount one to your AR-15?”
We can’t think of a reason why you wouldn’t have one on a defensive AR-15, but if you can come up with something, let us know down in the comments.
What to Look for in a Good Flashlight
Now that you’ve decided to mount a flashlight onto your AR-15, don’t go out and buy the first tactical light you come across.
After all, if you use a gun-mounted light for self-defense purposes, you’re going to want one that you can depend on when in a pinch.
So how do you pick the best one?
Here are some things to look for when shopping around for your tactical flashlight:
- Dependability – make sure it’s easy to operate and is guaranteed to switch on you press its button.
- Weight – your AR-15 is meant to be a lightweight rifle. You want to make sure you add a flashlight that isn’t bulky and puts excessive weight on your gun.
- Durability – a weapon-mounted flashlight needs to be shock resistant and able to withstand its batteries and internal parts being knocked around from running.
- Battery power – you want a light that’s not going to suck the power from your batteries. With the advancements in LED technology, many newer LED flashlights provide better battery life and brighter light than their incandescent counterparts.
- Lumens – to put it as simple as possible, lumens are how the brightness of the beam is measured; the more lumens, the brighter the light. Anywhere between 300 – 600 lumens seems to be bright enough for close-range tactical situations.
Mounting the Flashlight
Where you decide on your AR-15 to mount your flashlight depends on your personal preferences. When mounting your light, ask yourself the following:
- If I mount it on top (12 o’clock) will it get in the way of my optics or sight? (Probably so, yes)
- Do I plan on wearing a sling that pulls the gun close to my body? If so, will the light get in my way?
- Is the light in an easy-to-access location?
Some shooters like to mount the light to the side opposite of their dominant hand because they feel it’s easier to switch the light on. However, with pressure switches readily available, you can mount your light anywhere and put the switch in a convenient location.
Once you’ve determined placement, it’s time to mount the flashlight to your handguard. The A 2” accessory rail by Magpul ($6) is the perfect lightweight accessory for mounting your flashlight on either side of your handguard.

You also need an actual mount to attach the light to. If you don’t want something complex, stick with your run-of-the-mill 1” ring. Alternatively, Accushot’s UTG High Profile ring ($14) is durable and easy to install.
A 1” ring is all you need to mount a flashlight to your AR-15

You also want to learn how to properly use your flashlight, otherwise it can be a dangerous hindrance instead of a tool.
Here are some things to remember when searching the area with your weapon-mounted light:
- We shouldn’t ever use new safety equipment without proper training – consider registering for a training course for gun-mounted flashlights.
- Never use a gun-mounted light for things you’d use a regular flashlight for – only use it for situations where it’s likely you’ll shoot your gun and need visibility.
- Remember that pointing your gun-mounted flashlight is the same thing as pointing your AR-15. Same gun safety rules apply.
- If using your light in a safety situation, switch it on only when needed. Use your light when clearing a room or looking down a hallway. Leaving it on will hinder you and give away your position.
- Look into nighttime shooting events such as Crimon Trace’s Midnight 3Gun to get used to your new rig.
