It’s rare to find anyone with an AR not interested in hitting their target, but — depending on the purpose of your firearm — the right approach to optics can vary wildly. The good news is there are lots of products to choose from; be it traditional scopes like those from Burris, Nikon, or Bushnell, or more tactical products like those from Aimpoint, EOTech, and Trijicon.

Comparison of the Best AR-15 Lasers

Below is my list of the best AR lasers for 2021. I list the best choices in terms of value, performance, design, and cost.

Important AR-15 Laser Features

The first step in choosing a high-quality AR-15 laser is to determine the purpose for which you need one. Is it for home defense? Is it for a faster sight picture? Is it for hog hunting at night? Do you need a light and laser combination? 

One sighting system for those who appreciate a visual indication literally beamed onto their target, is the laser. 

Many combat operators will use a laser to speed target acquisition. While the perception of lasers may be that of an urban combat tool, a quality laser paints a target out to 300 yards or more — even in broad daylight. Higher-end lasers may also include a pulse option which makes it easier to lock onto a target at longer distances. 

The old adage that “one is none, two is one” applies as much to tactical professionals as long-range enthusiasts, so we dove deep into the world of AR lasers to separate the wheat from the chaff on these tools of the trade.

1. Intended Purpose

Determining how you’ll use the product will help you choose the right laser or laser/light combination. It will also help you determine if battery life should be considered, the correct mounting option, location on the rifle, and more.

2. Rail Fit

Naturally, your preferred AR laser should use the same mounting system as your handguard.

The right laser will integrate into your AR-15 setup without disrupting its configuration or requiring unwieldy attachments. Most rifles come with a Picatinny rail, but not always. Is your rifle set up on M-Lok or KeyMod?

Will you an additional adaptive plate to mount your laser?

3. Mounting Location

There are several considerations for laser-mounting options on an AR-15 — key amongst them is identifying the location where you should mount it.

A top mount orientation can work well depending on your hand placement. A riser on the optic can help keep the sight plane clear.

Examine how you naturally grip your rifle. Do you have a hand stop? Do you reach out to the end of your handguard close to your front sight? Are you right or left-handed? 

Assessing how you naturally use your rifle will help tremendously for determining the right location of your future laser and the best product option for you. The last thing you want is to throw off the balance and usability of your rifle by selecting the wrong laser.

4. Easy-to-Reach Controls 

Some lasers are paired with lights, which opens the door to an array of functions & uses. Depressing a pressure pad or activation switch will often cycle through the functions from light only, laser only, a combination of both, or even strobe functionality. 

If you’re planning for a combination laser/light, consider the location of the controls to ensure you can easily reach and activate the switches on the device. 

Ambidextrous controls are a very useful feature as they can prevent confusion in a stressful situation or if a family member needs to borrow the rifle it’s easy for all parties to use.

5. Multi-Rifle Needs 

The most common mounting systems are a basic Picatinny rail, Weaver-style rail, or a quick detach lever. Other designs integrate the laser into the grip or hand stop. Determine which of these you’ll need and if the addition of a new grip or hand stop is a feature you want on your rifle.

Will you be using this laser across multiple rifles? If so, a quick detach mount will make it easier to toolessly swap lasers from one rifle to the next.

6. Sight & Laser Combos

If you are running red dot sights on your rifles, consider a side-mount or under-mount orientation (to the side or beneath the handguard). 

This will prevent your laser placement from disrupting the sighting plain and keeps it out of the way. 

If red dots are the most common sights on your current rifles, a red laser may be the right choice because the colors will match — making it easy to pick up visually.

7. Laser Colors & Intensities

A side-mounted green laser is easy to see and can make the controls easy to reach.

Laser color and lumen count are two other considerations. Red lasers and green lasers will have varying degrees of visibility in different light settings. Their effectivenetss can also vary drastically from one person to the next. Before making a purchase, ask a gun shop to demo a laser for you or try a friend’s laser to see which color works best for you.

Red or Green?

A red laser sight is generally the less expensive option, is more commonly available, and is considered old school — meaning its the color most shooters are familiar with. They’re also slightly more difficult to see than green lasers, which can work to your advantage if stealth is your goal.

Green lasers are visibly brighter which can make them a better option for situations which make it harder to see the laser, such as daylight or long-distance shooting. Human eyes are much better at detecting green light than red, and understanding why requires a little detour into biology. The three types of photoreceptor cells in the human eye (called “cones”) contain photo-pigments that are designed to sense color wavelengths.

Together, the cones communicate the colors we’re seeing to our brain. Our eyes pick up green light most easily due to the receptivity of these cones to the wavelength of green light. Simple, really.

8. Lumens

Adding a weapon-mounted light to a home defense weapon is a good idea for low-light situations, increasing situational awareness, and as a defensive tool for blinding or disorienting an assailent. 

When hunting at night, a flashlight is necessary to see your target and — just as importantly — what’s beyond it. This is when lumens come into play.

It bears repeating, defining the purpose of your laser/light combination will help determine the lumens and the distance required. A compact, 300-lumen flashlight will not illuminate a field like a 1,000-lumen rifle light will. 

A light that provides a strobe option is great for disorienting an intruder by decreasing their direct and peripheral vision. Blinding flashes also blow out their night vision, which induces fear and can reduce both their desire and ability to use force. A blind assailant is much less likely to assault anyone, especially if they know there’s a rifle on the other end of the light.

9. Battery considerations

Another consideration when choosing a light and laser combination is the duration of use. Do you plan on using this for hours at the range? Do you plan to use it on overnight hunts? 

The intensity of the light and the duration of activation will impact battery life. Many of the lasers on the market are powered by CR123A batteries, which are readily available but not the most powerful. Look for battery saving features on a laser and light — some can last almost a full day or automatically shut off after a certain period of inactivity, saving your batteries for another day.

The Best AR-15 Lasers Reviewed

1. Crimson Trace LiNQ Tactical Light

This Crimson Trace device is a two-piece kit: a green laser with a 300 lumen LED flashlight and an activation switch built into an AR-15 grip. The AR-15 grip is unique because it uses Crimson Trace’s wireless connection, called LiNQ which allows complete control of the laser and light through the grip itself. This grip-based activation eliminates the need to reach for the forend and activate the light or laser. 

When pressure is applied to the grip switch the laser and light activate. The only downside is without a proper grip neither the light nor laser will be activated. While a quite natural means of activation, manipulating the grip switch to ensure the laser has been triggered can take some practice.

2. Streamlight TLR-2 Flashlight with Laser

Once mounted, the laser can be adjusted for both windage and elevation so you can dial in the placement on the target.

3. TruGlo Laser Red Trupoint Light Combo

This TruGlo laser/light combo mounts directly to Picatinny or Weaver-style rails. It comes with interchangeable backplates for right or left-hand use, which means when installed it can only be activated from the side onto which it’s mounted. 

The Trupoint also features a quick detach lever for fast removal if mounting onto another rifle.

The Streamlight TLR-8 is a 500-lumen LED flashlight and laser in one device, machined from aircraft-grade aluminum. The CR123A battery limits the light to a 1.5-hour life, but provides the laser 18 hours worth of run-time. 

The left and right switches provide ambidextrous operation for ease of and it mounts onto any Picatinny rail.

7. Viridian HS1

The Viridian Hand Stop Laser attaches to all M-Lok rails and can be sighted in with both windage and elevation adjustments. 

The laser activates when pressure is applied to the hand stop and works with any grip style — thumb-over-bore, C Clamp grip, or a traditional off-hand rifle grip. It’s an ideal home defense laser and incredibly straghtword to use — which is a must have for stressful situations. The Viridian laser is only available in green, but offers up to 90 minutes of run-time and is visible for up to 2 miles at night.

8. TruGlo Micro-Tac Green Laser

  • Next generation, High-Efficiency Superconductor Laser Diode Green Laser; Operating temperature:...
  • This product is a Class 3R (IIIa) with power output <1mw and wavelength 500-540nm

This TruGlo laser has an incredibly small profile and takes up almost no room on a handguard. The laser automatically shuts down after 5 minutes to preserve battery life, and easily mounts to any Picatinny or Weaver-style rails. A key feature is the ambidextrous push-button for both left and right-handed shooters are mounted in a way that’s easy to activate but recessed to avoid accidental activation.

Types of AR-15 Lasers

  • Laser Only: AR lasers with a laser only (no light) provide users with a small, mountable option with a single purpose — putting a dot on a target. These lasers can be incredibly lightweight and small thanks to the limited amount of tech — they’re little more than an LED and a switch — so they’re also straightforward and quick to use. Those who want to keep their loadout as small and purpose-driven as possible (or maybe already have alight) will appreciate these kinds of lasers.
  • Laser & Light: Laser/light pairs are the ideal solution for AR users with limited rail space or those who want to combine these similar purposes into a single unit. These units often include several unique features designed to provide users with different options for different preferences. You will often find toggle options for using these in specific modes: light-only, light & laser, and laser-only, sometimes with strobe or pulse options. This means there’s more of a learning curve, and using them can be more complicated than a simple laser-only option. They can also be more expensive and more prominent, but the addition of the light means more utility, all things being equal. 
  • Sight & Laser: Some AR sights will tack on an LED laser which can be activated with a button toggle on the sight unit itself. These often look similar to standard sights but project a beam, which can simplify the process of aligning the beam and sight reticle. You have fewer mounting options with these — the beam & controls are literally on the sight unit — but you’re not adding any weight to the end of your rifle or using any rail space.

Benefits of AR-15 Lasers

While it may seem obvious, there is a very good reason special forces units, soldiers, marines, and other operators run lasers on their rifles. A reliable laser communicates to the user and the target where their shot will land — which provides a level of certainty that no other style of optic or accessory can achieve.

AR lasers are bright, tough, and durable, capable of dealing with the kinds of punishment like tactical operators are likely to encounter, all while staying true and on zero. This additional reliability increases performance in high-stress situations and provides a clear, visible way to help you get the job done right.

AR-15 Laser Pricing

When it comes to picking at a quality AR laser, you certainly get what you pay for, so consider splurging a little to get something you’ll be happy with. As we like to say, AR lasers under $75 live in one of two categories: garbage or gimmicks.

You can spend two lifetimes digging through off-brand lights or Amazon specials without touching a hint of quality, although budget-friendly options are available from some known brands. There are a few exceptions to this rule — Olight makes good quality light/laser combos that are both durable and perform and are often on the lower end of the price spectrum.

That said, most people will eventually drop somewhere between $100 and $350 for a proven, durable, well-engineered AR laser. These lasers offer high lumen outputs, bright lasers, bullet-proof build quality, and a number of other added features. 

How we chose these products

When reviewing guns or gear, we get our hands on as many products as possible, but there are times when certain products or categories are a real challenge — be it availability, cost, or simply a lack of resources — we can get stymied going hands-on with all the potential candidates. Plus, the AR laser category is massive, so rather than present a never-ending list of all the lasers on the planet we selected those which we felt best represent the price points laid out above — giving you a solid representational list to serve as a jumping-off point for your own research (you are going to do you own research, right?)

To avoid disappointment or steering you in the wrong direction, we bolster our own experience with conversations with experts, comb through reviews on retailer sites & sales data, review industry publications, other blogs, and otherwise surface the best information available.

We aim for all thriller, no filler, as they say.
