Full description

Description

If you're a realism seeker, the EMG Daniel Defense® MK18 MOD 1 GBBR should pique your interest! A full metal build officially licensed by Daniel Defense via EMG, this MK18 is as realistic as it gets, with shoulder thumping recoil, a realistic manual of arms and even internals which are remarkably close to those of a real AR-15, even compared to other GBBRs. If you collect realistic replicas, you'll love this!

Inside, this WA System-based GBBR has been treated to steel trigger group components and a steel bolt catch. This will considerably improve reliability and extend the lifespan of this build compared to the usual zinc alloy parts. Also present is a 6.05mm tightbore inner barrel, granting an accuracy edge with high-quality BBs. If you put realism first and need a detailed MK18 build, the EMG Daniel Defense® MK18 MOD 1 GBBR is a solid choice!

Starting at the tip of the 10.3-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 MK18 rifle.

If the birdcage is a bit too pedestrian for your style or you are going for a special forces build, the 14mm CCW male threading at the tip of the outer barrel allows alternative flash hiders, suppressors or tracer units to be fitted to complete the look.

Moving rearwards, we come to the handguard, which is constructed from aluminium and is precisely machined using CNC technology. It doesn’t get more sturdy than this. With 10 inches of rail length available, you have plenty of space to add a myriad of accessories to suit your playstyle and loadout. The handguard has 20mm Picatinny rails at the 3, 6, 9 and 12 o'clock positions, ready for your mission essential accessories.

The length of the rail allows you to position your accessories wherever you need them, be it a vertical or an angled fore grip, a tactical flashlight or a PEQ laser unit, or the whole lot! Another benefit of the free-floated rail design is that it prevents force from being applied to the barrel, allowing you to feel safe in the knowledge that your accuracy will be retained as much as possible when shooting from a supported position or steering the platform between targets.

The iron sights of the MK18 are removable polymer flip-up aperture sights which mount to the upper 20mm Picatinny rail. Elevation adjustments are applied via the rotary dial below the front iron sight blade, and windage adjustments via the dial on the right side of the rear sight. The rear sight aperture can also be adjusted up and down via the dial on the sight itself, just below the aperture, for those who prefer to keep the front sight as is and apply all adjustments on the rear sight.

The receiver of the MK18 is similar in form to every other AR out there, with the exception that, because it does not contain a gearbox, the receiver can be realistically sized. This results in a slim feel to the rifle, and a positively skinny pistol grip, marking this out as a GBBR and making it genuinely hard to distinguish from a real AR. Obviously, this doesn't make it better or worse for skirmishing, but if you are like us and appreciate attention to detail and faithfulness to the real article, you will feel a strange sense of satisfaction handling this bad boy.

On the left side of the receiver, we are treated to engraved Daniel Defense trademarks, perfectly matching the real DDMK18 build. The upper also features laser-engraved markings, with the calibre marking at the front, and the model name "MK18" at the rear. Like those on the lower, these markings are a dead-on match for real MK18 rifles built by Daniel Defense.

The bolt catch is right where we would expect; on the left side of the receiver, smack bang in the centre. On a GBBR, the bolt catch works exactly like the real thing, allowing you to quickly return the bolt carrier to battery after a reload and avoid using the charging handle. To guarantee reliability, the bolt catch is made from steel, ensuring it will never fail, even under hard use.

The fire selector lever is located on the left side of the receiver, allowing for safety, semi and fully automatic settings at 90-degree intervals. This means you can quickly switch between fire modes, but be safe in the knowledge that you won't accidentally move the selector into a fire position when you don't intend to. Worth noting is that, like the real steel AR platform and most other GBBRs, the fire selector cannot be set to "SAFE" without first cocking the rifle.

The trigger guard is the standard mil-spec flat type, keeping things in line with the real MK18 MOD.0 issued to US Special Forces. The pistol grip is the legendary "A2" type, first seen on the M16A2 and common on military builds. The grip boasts textured panels on each side for improved traction and a finger ridge to help support and control the front end of the rifle when held in the "high ready" position. Like its receiver, the MK18's pistol grip is realistically sized and is compatible with GBBR and real steel pistol grips with some simple modifications.

Following the sling plate, we come to the stock of the MK18, which is the usual M4/AR-15 format of a 6-position buffer tube with an adjustable stock. This stock can be locked into any 1 of the 6 positions and can be adjusted to suit any body type or loadout.

The stock is the EMG Alpha Combat Ready stock, boasting a rubber butt plate and an internal storage compartment which can be used for whatever you like. The Alpha stock also features a sling slot, ideally suited to strap-style slings. As with all AR buffer tube-equipped platforms, if you prefer a different stock solution, swapping the stock out for an alternative for AR buffer tubes is quick and easy.

Inside, this WA System-based GBBR has been equipped with robust steel trigger group parts, improving long-term reliability and ensuring you'll never need to upgrade. The bolt catch is also made from steel, so this high-wear component has the strength to go the distance. Also inside is a 6.05mm tightbore inner barrel, enhancing accuracy with high-quality BBs and providing a slight FPS boost from the same pressure gas.

While the GBBR lifestyle is as challenging as it is rewarding, you simply cannot have a more realistic experience with any other type of platform. If you love realism, tinkering, and working hard in-game like the real warriors do, the EMG Daniel Defense® MK18 MOD 1 GBBR should be in your sights!

Special Instructions

This is a Gas Blowback Rifle. GBBRs require maintenance and careful handling, and we do not recommend them for new skirmishers. Things to watch out for if this is your first GBBR:

  • The rifle cannot be put into "Safe" mode without first being cocked. Generally, the best way to store a GBBR is with the magazine removed, the rifle uncocked, and the fire selector set to "semi".
  • The HOP-up adjuster for this WA system GBBR is on the bottom of the outer barrel and is accessible with the lower handguard section removed or using a small tool through the handguard ports.
  • GBBRs need to be cocked before the first shot, just like a GBB pistol. It is important that you do not double-load a GBBR, as this can break the nozzle. We recommend clearing the chamber of BBs with a cleaning rod in the event that you finish firing mid-magazine and the bolt does not lock back and show an empty chamber.
  • GBBRs generally use higher-pressure gas than GBB pistols due to the extra weight of the bolt. We recommend Green Gas (NUPROL 2.0, VORSK V6, ASG Ultraair) for general use and Red Gas (NUPROL 3.0, VORSK V8) for cold weather use.
  • The faster you shoot a GBBR, the less accurate it will be. This is due to pressure variance as the gas reservoir cools down. Full auto is basically for fun, and these rifles run far better when used in semi-auto mode.
  • Like a GBB pistol, GBBR magazines require maintenance. We recommend leaving a small amount of gas inside the magazine when stored, and not storing the magazines in a cold or damp environment. Magazine seals and valves will need lubrication and to be kept clear of dust and debris.
