You also get a standard tailcap and zip ties for cable management. This complete package means you can get up and running quickly without having to purchase additional accessories.
The ProTac Rail Mount 2 uses Streamlight’s Ten-Tap programming, allowing you to choose between three different operating modes: High/Strobe, High Only, or Low/High. This flexibility is great for adapting the light to different situations. Personally, I keep mine set to High Only for simplicity’s sake, but it’s nice to have options.
Construction-wise, the ProTac is rock solid. It features an aircraft aluminum body with an anodized finish, making it highly resistant to impacts and abrasion. The lens is made of impact-resistant tempered glass, which has held up well to all the abuse I’ve thrown at it.
One potential drawback to be aware of is that if the remote switch is damaged, you’ll need to replace the entire tailcap unit. It’s a good idea to keep the standard clicky tailcap in your kit as a backup just in case.
While not as insanely bright as top-tier lights, the ProTac Rail Mount 2 hits the sweet spot of performance, durability, and affordability. It’s my go-to recommendation for most AR owners looking for their first quality weapon light or those on a tighter budget.
Modlite PLHv2 18650 – Best High-End AR-15 Flashlight
The Modlite PLHv2 is another ultra-premium option that gives the REIN 3.0 a run for its money. With 1,350 lumens and 54,000 candela, it offers an incredibly far-reaching beam that can illuminate targets at extended distances.
What I love about the PLHv2 is the modularity. You can easily swap between different light heads, body tubes, and tailcaps to customize the setup for your specific needs. I run mine with the 18650 body for maximum runtime, but you can also use the compact 18350 body to shave off some weight and length.

The TIR lens produces a beam with a bright center hotspot for positive target identification, surrounded by a softer spill that helps maintain situational awareness. In my testing, I found it more than capable of illuminating targets out to 100 yards, while still being useful for close-quarters work.
What really impresses me about the M300C is how it manages to maintain Surefire’s legendary durability in such a compact package. The body is constructed from aerospace-grade aluminum with a hard-anodized finish, making it highly resistant to wear and corrosion. I’ve run this light hard on multiple builds, and it’s held up beautifully to repeated impacts and harsh conditions.
The M300C runs on a single CR123A battery, providing about 1.25 hours of runtime on high. While this might seem short compared to larger lights, the compact size allows for easy carrying of spare batteries. Plus, the lower output means it doesn’t chew through batteries as quickly as some of the ultra-high output options.
Mounting options are plentiful with the M300C. It comes with a low-profile Picatinny mount, but it’s also compatible with a wide range of aftermarket mounts. This allows you to position the light exactly where you want it, whether that’s at 3, 6, or 9 o’clock on your handguard.
One potential drawback of the M300C is that it doesn’t come with a pressure switch in the base configuration. However, it is compatible with Surefire’s extensive range of tailcaps and switches, allowing you to customize the activation method to your preferences.
At around $300, the Surefire M300C Scout Light Pro isn’t cheap. However, for those who prioritize compactness and reliability above all else, it’s a worthy investment. If you’re running a short-barreled rifle or just want to keep your setup as streamlined as possible without sacrificing quality, the M300C is an excellent choice.
Factors to Consider When Choosing an AR-15 Flashlight
With so many great options on the market, choosing the right AR-15 flashlight comes down to your specific needs and budget. Here are some key factors to keep in mind:
Output: When looking at flashlight output, you’ll often see two numbers: lumens and candela. Lumens measure the total amount of light emitted, while candela measures the peak beam intensity. For general use, a light with 500-1000 lumens is usually sufficient. However, if you need to illuminate targets at longer distances, pay attention to the candela rating. Higher candela means a more focused, far-reaching beam.
Runtime: Consider how long the light will run on high. Longer runtime can be crucial for extended use. Most quality AR-15 flashlights will offer at least 1-2 hours of runtime on their highest setting. If you anticipate needing light for longer periods, look for lights with lower output modes or consider carrying spare batteries.
Controls: The method of activating your light is crucial for efficient use. Many AR-15 flashlights come with both a tailcap switch and a remote pressure pad. Tailcap switches are great for momentary or constant-on activation and are very reliable. Pressure pads allow for more flexible mounting options and can be easier to activate quickly in some shooting positions. Consider your grip style and preferred shooting stance when choosing between these options.
Durability: An AR-15 flashlight needs to withstand not just the recoil of your rifle, but also impacts, harsh weather, and potentially even submersion. Look for lights with rugged construction, preferably made from aircraft-grade aluminum with a hard-anodized finish. Waterproof ratings are also important – an IPX7 or IPX8 rating indicates the light can withstand temporary submersion.
Mounting: Ensure the light is compatible with your rail system. Most AR-15 flashlights come with Picatinny rail mounts, but if you’re running M-LOK or KeyMod handguards, you may need to purchase separate mounts. Also consider where on your rifle you want to mount the light. Some shooters prefer a 12 o’clock position, while others opt for 3, 6, or 9 o’clock mounting.
Size and Weight: A compact, lightweight option may be preferable for a more nimble setup, especially if you’re running other accessories like optics or lasers. However, larger lights often offer more output and longer runtimes. Consider the overall balance of your rifle when choosing a light.
Battery Type: Many AR-15 flashlights run on CR123A batteries, which offer long shelf life and good performance. However, rechargeable options like 18650 batteries are becoming more popular due to their higher capacity and cost-effectiveness over time. Some lights offer “dual fuel” capability, allowing you to use either type.
Beam Pattern: Different lights offer different beam patterns. Some focus on a tight, far-reaching beam for long-distance target identification, while others provide a wider flood for close-quarters use. Many modern lights strike a balance between the two. Consider the environments you’re likely to use the light in when evaluating beam patterns.
Additional Features: Some lights offer programmable modes, allowing you to switch between different brightness levels or activate a strobe function. While these can be useful, remember that simplicity often wins out in high-stress situations.
Budget: Quality weapon lights range from around $100 to $400+. While it’s tempting to go for the cheapest option, remember that a weapon light is a critical piece of gear. It’s often worth investing in a higher-quality light that you can depend on when it matters most.
Maintenance and Care Tips for Your AR-15 Flashlight
To ensure your AR-15 flashlight continues to perform reliably, here are some maintenance tips:
- Regular Cleaning: After each use, especially in dusty or muddy conditions, clean your light with a soft cloth. Pay special attention to the lens, as dirt or smudges can significantly reduce light output.
- Battery Management: If you’re not going to use the light for an extended period, remove the batteries to prevent potential leakage. For rechargeable batteries, try to keep them at about 40-60% charge for long-term storage.
- O-ring Maintenance: Periodically check the O-rings that seal your light. If they appear dry or cracked, apply a small amount of silicone grease to maintain their seal.
- Switch Care: Keep an eye on your activation switches, both on the light itself and any remote pressure pads. If you notice any sticking or inconsistent activation, it may be time for a replacement.
- Mount Tightness: Regularly check that your light is securely mounted. Recoil can cause mounts to loosen over time, so it’s a good idea to check and re-tighten as necessary.
- Lens Protection: Consider using a clear lens protector if you’re frequently shooting in environments where debris might impact your light. This can prevent costly damage to the main lens.
- Waterproofing Check: If your light has been submerged or exposed to heavy rain, check for any water ingress. If you find moisture inside, disassemble the light (if possible), dry thoroughly, and consider replacing O-rings.
