Cloud Defensive REIN on SCAR17 KDG rail
The FN SCAR series rifles are people's favorite. In this buyer's guide, let's take a look at the best weapon lights for SCAR 16 & 17, including IR and white LED lights.

Out of all the light products you can buy, our favorite is the Modlite OKW for providing high lumens and high candela for distance shooting.

In addition, we also recommend the KDG SCAR upgrades kit that includes a new MLOK modular handguard for more rail mounting space, and many more.

Let's check it out...

Modlite System is the top-performing Surefire Scout alternative you will ever find on the market today.

Even though it's not a light currently adopted by the military, but it's definitely a hot product in the LE and firearm enthusiast communities.

The reason why we push for Modlite for the SCAR is for the higher candela ratings (OKW head) for the extreme long-distance throw, and it accepts the same pressure switch used on Surefire.

It's a great long gun specific WML (Weapon Mounted Light) system for better threat control and longer distance target identification in low light conditions.

Hotter Beam At Longer Distance With Higher Candela

The Surefire Scout M600DF is great option, but the MODLITE's performance and quality is just another notch higher.

If you currently own the SF M600DF, and you want to squeeze more performance out of it. you have the option to replace the original Surefire KE2-DF head with the following heads:

  • IR 850 (1100mW)
  • PLHv2 (1350 lumens / 53K candela)
  • OKW (680 lumens / 69K candela)

If you already have a Surefire M600DF, but you’re not happy with the throw performance on a medium / long range rifle, then the Modlite is the solution.

If you don’t have a Surefire M600DF already, we highly recommend getting the Modlite right off the bat.

Surefire M600DF Scout

Still the best Scout light - Surefire and FN SCAR just goes together very well especially you get the FDE color.

The M600 Scout Dual Fuel is the latest model that can produce up to 1500 lumens using the 18650 battery, or use 2 CR123A for 1200 lumens.

Not only it puts out blinding white light lumens, but its versatile TIR beam maximizes peripheral illumination & target at longer range (150 yards)


Virtually indestructible - As always…the Surefire is made of MilSpec hard anodized aerospace aluminum, fully waterproof & battle proven.

The modularity we love -  The light Accepts MODLITE Heads such as OKW, PLHv2 and IR, so you can upgrade your Surefire M600DF anytime you want for specific tasks.

Or on Brownells.

Cloud Defensive OWL

The Cloud Defensive OWL Is the strongest weapon light on the market today, even more so than the Surefire Scout.

If you want a tactical weapon light like the BE Meyer MAWL with an integrated pressure switch on the AK, then the Cloud Defensive OWL 1250 Lumens is what you need.

Capable of reverse switch orientation for right & left handed shooters simply by reassemble the unit. It’s perfect for military applications as well as home defense.

Regardless of your dominant hand, the OWL will work for dominant hand shooting & transition side shooting.


This light is designed for long range illumination, so if you’re shooting your AK long range, then this light will illuminate as far as 300 yards with focus beam strong enough for you to identify targets.

No tape switch cord, no remote switch wiring, this light has a built-in pressure activation switch & tail cap switch.

  • Over 50000+ Candela for intense focus and reach, 2X more than others
  • Orient the light for ambi use, just like the BE Meyer MAWL
  • Indestructible EVEN after unrealistic torture tests
  • Great ergonomics for most shooter
  • Rechargeable battery

SCAR Rail Handguard Accessories

In order to have MORE rail space to mount weapon lights and laser devices on the SCAR weapon platform, we have to have an extended rail system.

Lucky we do have them available. Out of all the options out there, the Kinetic Development Group MREX Rail is the best, but it has been discontinued.

Check here on OpticsPlanet to see if it's still available.

Don't worry, the next option will be the PMM SCAR extension rail for CQB SCAR, or the PWS rail extension.
