5 Best Weapon Lights For MK18

In this buyer's guide, let's check out some of the best weapon lights for MK18.

There are tons of options available, and these are what we think are the best based on their beam performance, beam tint, throw, durability and value of money.

Let's take a look

5 Best MK18 Weapon Lights

Cloud Defensive REIN - Best Overall

Why Pick The REIN - The Cloud Defensive REIN is the next generation high candela scout light to help shooters see further in the dark. Besides the Surefire M600DF, this is an awesome light for MK18.

Better Target ID - See as far as 180 yards with that insane 60K candela throw to ID targets clearly while other low end lights just can't do

Full Size Or Mini - User can pick the full size or compact model (Both work well on MK18, compact model is preferred for SBR)

Uses The Same Scout Light Mount - Use any scout light mounting accessories from Surefire, Arisaka, IWC...etc can be used with the REIN (Works for KeyMod, Picatinny & M-LOK)

Better Color Rendition - (Slightly warmer) Neutral tint white light gives the shooter more accurate color rendition under low light to properly ID targets.

Non-Snag Cable Wiring - The REIN's new tail cap design allows the user to switch its orientation based on where the light is mounted on the handguard.

• No more force swing the cable around the switch to the other side
• No more snag hazard & zero exposed cable
• No more bending stiff switch cable that could degrade voltage flow
• No more excess cable sticking out
• No more zip tie
• Perfect for clean SBR handguard setups

Rechargeable 18650 Batteries - The built-in battery jack inside the body allows the use of a wide variety of batteries from unprotected cell to rechargeable (Not all 18650 batteries are made the same length-wise)

Serviceable S& Tool Steel Bezel Lens - It's 3mm thick lens to significant beef up the durability of the light 

If the lens break, all you have to do is to replace the lens by disassemble the bezel in less than a minute give or take.

Cloud Defensive OWL - Best Integrated Design

Why Use The Cloud Defensive OWL (1250 lumens) - The OWL is significantly larger than other lights, but it is a durable light that is as powerful as holding a stadium spot light to lit up the area.

For anyone shooting in the dark past 150 yards to 300 yards, this is THE flashlight to get for the MK18.

See As Far As 180 Yards - Just like the Cloud Defensive REIN, the throw is insane for the money you pay for

This light has that extra beam intensity to lit up far away targets that are generally hard to see as a silhouette in the dark.

Reversible Control Switch Ergonomics - It feels like the BE Meyer MAWL. The integrated pressure switch design allows the light to be mounted on either side of the rifle, for lefty & righty shooters.

MK18 CQB Light Setup

Do You Need Dual Lights Setup?

Having two weapon lights on the rifle will increase the weight of the gun, and it's not about adding two white lights.

Generally speaking, a dual light setup usually involves

• White light
• IR light (for night vision use)

MK18 Weapon-Mounted Light Tactics

The light setups for a MK18 varies a lot depend on the mission profiles. 

Most MK18 setups we see are combinations of Scout lights & laser devices hooked up to a remote pressure switch for good control ergonomics.

Since there are so many ways to configure lights on the rifle, we can't show you everything in this guide, but we can give some tips:

• Put the pressure switch on the 12 o' clock on the handguard so the hand can operate it while gripping tight on the handguard
• Mount laser device on the 12 o' clock position on the handguard and tuck the light next to it using an offset light mount
• Try to mount the light bezel parallel to the muzzle device so it doesn't cast shadow

Here we have some reference pictures for you to check out.

Laser & Light Setup Requires Remote Pressure Switch

The most popular light setup for the MK18 you can find on the internet are pretty much the combination among:

• Surefire Scout
• Streamlight
• L3 ATPIAL C
• Steiner DBAL
• BE Meyer MAWL
• Other Ninja looking accessories

It's definitely a rifle that has a strong root in the night vision community. So when you setup the MK18 with a visible white light/Laser + IR, you want to operate them using one consolidated control panel (Remote Pressure Switch)

If this is what you want to experiment with, we recommend the TNVC TAPS pressure switch, as you can program it to activate 2 lights at the same time, or you can program it to activate each light separately.
