Description

If you like the looks of the MK18 MOD.1 but the hefty quad rail front end puts you off, the EMG Daniel Defense DD4™ MK18 RIII is the modernised MK18 you need. With a perfect replica of the latest M-LOK handguard from Daniel Defense up front, this MK18 points quickly with the agile handling of a modern M-LOK-equipped carbine.

Like other DD licenced rifles from EMG, the DD4 MK18 also comes equipped with a full complement of licenced Daniel Defense parts, including the "Grip-N-Rip" charging handle, "Tornado" pistol grip and DD collapsible buttstock. The receiver is adorned with a mix of crisply engraved trademarks and white laser engraved calibre and model markings, completing the authentic Daniel Defense external build.

Inside you will find a reinforced version 2 gearbox kitted out with a vast number of pre-upgraded parts including a high-speed motor, CNC steel 13:1 ratio high-speed gearset and the CYMA Platinum MOSFET to keep it all in check and allow the use of 11.1V LiPo batteries. The DD4 MK18 is also packing a 6.03mm tightbore with an alloy rotary HOP-up unit, giving it considerably more range and accuracy than one might expect from a compact 10.5" barreled setup.

Starting at the tip of the 10.5-inch outer barrel we can find a birdcage type flash hider pre-installed on the barrel’s 14mm CCW male threading. The birdcage design also goes hand in hand in terms of looks with the handguard, jutting out two inches ahead for a compact front end, and is the appropriate flash hider design for the real Daniel Defense DD4 RIII MK18 rifle.

The handguard replicates the latest and greatest MK18 style handguard from Daniel Defense, known as the RIS III 9.5-inch. This handguard keeps the military applicable aspects of the original MK18 handguard, specifically the ability to remove the lower section and mount an M203 grenade launcher but boasts a slimmer profile and reduced weight thanks to its use of M-LOK negative space attachment slots instead of 20mm Picatinny rails.

M-LOK slots are present at the 3, 6, and 9 o'clock positions with additional slots at the offset angles in the ideal position to mount a tactical flashlight and keep it tight into the weapon for reduced snagging. M-LOK slots allow M-LOK accessories to be directly mounted but you can also make use of 20mm Picatinny rail adapters for M-LOK if you have a preferred 20mm foregrip, flashlight, bipod or laser aiming module.

Like the original MK18 RIS II, the RIS III handguard features a 20mm Picatinny rail on its upper surface which runs back to meet the receiver rail seamlessly, allowing for optical sights of practically any length to be mounted despite the short overall length of the DD4 RIII MK18. Also present on the handguard are a pair of QD sling sockets, allowing for QD sling swivels to be mounted and paired with either the rear sling plate, QD sockets or footman loops on the stock to allow for a two-point sling.

Pre-installed on the top rail, we are treated to a set of flip-up aperture iron sights which can be deployed by pressing the button on the left side of each sight. The sights are fully adjustable for both windage and elevation and protected on each side with protective wings to keep the sights set properly despite any mid-battle bumps and scrapes.

Next up, we reach the receiver which is a stunning showcase of licenced Daniel Defense trademarks, flawlessly engraved and a perfect match for the real DD4 RIII MK18. The left side of the upper receiver also includes a 5.56mm calibre marking in high-vis white laser engraving, together with the stylised MK18 RIII logo at the rear. The dust cover, found on the right side, also features DD markings and is constructed from high density polymer to match modern weight-reduced dust covers found on the latest H&K HK416 rifles as well as Daniel Defense's DDMK18.

The charging handle is located at the top rear of the receiver, and as we might expect, is a licenced Daniel Defense design. Known as the "Grip-N-Rip", the charging handle is ambidextrous, with enlarged latches on either side allowing for flawless functionality whether you wear gloves or not.

Pulling the charging handle back will pop open the dust cover and reveal the mock bolt carrier with its DD trademarks. The mock bolt carrier will also lock to the rear, allowing access to the rotary HOP-up unit. This unit is constructed from alloy for increased strength, allowing you to tune the DD4 RIII MK18 for your chosen ammo weight. Once your adjustment is complete, slap the "ping pong paddle" bolt catch on the left side to send the mock bolt home with a satisfying "clank".

The fire selector switch is located on the left side of the receiver, just above the pistol grip and is a standard M4A1 mil-spec design with a textured surface for optimal traction in wet weather. The selector provides 3 modes of fire; safe, semi-automatic and fully automatic, with a 90-degree throw between each mode. The selector switch is one of the best aspects of the M4 design, easily accessible and fast to use with enough distance between modes that it isn't easy to knock out of position inadvertently.

The magazine release button is over on the right side of the magazine well, a standard M4/AR-15 push button release but compatible with aftermarket ambidextrous alternatives. The button is surrounded by a raised protrusion in the receiver, known as the "magazine release fence" and designed to prevent the mag release from accidentally being pressed as the DD4 RIII MK18 rubs against your gear. Another great aspect of the AR-15 design, the magazine release is easily accessible from a firing grip, making for scorchingly fast reloads as long as you practice!

At the base of the buffer tube is an ambidextrous sling plate sandwiched between the receiver and the castle nut. This plate is constructed from steel to provide the prerequisite strength for use with a single-point sling. This sling point is ideal for a single-point bungee sling but can also be used with a two-point sling with the addition of a rail-mounted front sling point.

Following the sling plate, we come to the stock of the DD4 RIII MK18 which is the usual M4/AR-15 format of a 6-position buffer tube with an adjustable sliding stock. The buffer tube is compatible with any M4/AR-15 AEG stock you choose to mount, but the pre-installed stock really is fantastic, there is no need to swap it out!

The stock replicates the real steel Daniel Defense Buttstock, a precisely manufactured stock designed to eliminate lateral wobble and add ergonomic enhancements for a more comfortable shooting experience. The sides of the stock are sloped, similar to a crane stock but feature rubberised pads on the surface for a positively luxurious cheekweld. A QD sling socket is present on either side, ready for QD sling swivels, and the stock also includes conventional "footman loops", aka sling slots for standard rifle slings. The butt plate is also deeply serrated for extra grip and shaped to allow for a high hold and a more intuitive head position when shooting.

Inside the stock, we can find the battery compartment which is accessible with the butt plate removed. To do so, simply press the rectangular EMG marked section in the centre of the butt plate and it will pop straight off. Inside, you will see a Deans battery connector to which you mount your chosen battery. You can make use of either the buffer tube itself for your battery if you use stick batteries, or the hollowed "cheeks" of the stock if you prefer a crane/nunchuck battery. We recommend an 11.1V LiPo for this AEG due to its low voltage cutoff function, either a 1200mAh stick battery or a 1450mAh nunchuck battery.

On the inside, the DD4 RIII MK18's incredible rate of fire and trigger response is down to CYMA's finest AEG internals yet. Known as the CYMA Platinum E-Edition gearbox, the version 2 GB inside is equipped with a CNC machined steel 13:1 high-speed gearset, MOSFET and high-speed motor. The gearbox shell is also reinforced in all the key places for a long lifespan, and inside you will find 8mm ball bearing bushings, a CNC machined aluminium silent piston head and cylinder head set, a polycarbonate piston with a full rack of steel teeth and a ball bearing quick change spring guide. The inner barrel is also a tightbore 6.03mm example, adding accuracy potential so this CQBR length M4 can tackle long-range threats with ease.

If you're looking for the quickest and slickest MK18 platform yet, this is the one! With an aggressive militant aesthetic paired with a modern M-LOK handguard for improved handling and faster target-to-target transitions, this Zoomer MK18 will run rings around the older variant!
