  • Full metal construction
  • ZET System GBBR - TM compatible internals
  • Ferocious recoil, realistic handling - Just awesome!

If you have a taste for realism, recoil and a new challenge in game, the Noveske N4 GBBR from EMG will give you what you need. This Gas Blowback Rifle boasts full metal construction, licenced Noveske trademarks and internals based on the best of the best when it comes to GBBRs; the Tokyo Marui ZET system.

Not for the faint of heart or those who like to fight easy, a GBBR provides unparalleled realism with its realistic manual of arms involving loading the first round using the charging handle, counting your shots carefully due to low-cap magazines and taking your reloading skills to the next level thanks to its functional bolt lock. While a GBBR is a challenge to operate compared to a simple AEG, there is nothing that can touch a GBBR when it comes to its immersive firing experience and unparalleled realism.

Licenced by Noveske through EMG and manufactured by Double Eagle, the N4 has absolutely gorgeous externals, with a thick, hard-wearing finish that looks phenomenal and showcases the crisply engraved Noveske trademarks which tie the whole piece together. The N4 GBBR also has a full steel trigger group pre-installed, saving you money down the line on essential longevity upgrades required to keep a GBBR running in the long term. If you have been holding out on a GBBR, waiting for something to pop up that has the right balance of affordability, efficiency and aftermarket support, now is the time!

Description

If you have your ear to the ground on the latest real steel platforms sighted in the hands of the SEALs/DEVGRU, you will recognise the Noveske N4 Gen.3. This rifle is based on the M4/AR-15 but chambered in the .300 Blackout cartridge, a specialised suppressed cartridge making waves in the real steel world and now, finding its way into the hands of special forces. 

The EMG Noveske N4 Gen.3 GBBR is based internally on the much-lauded Tokyo Marui MWS ZET System, which is excellent news. The ZET system is leaps and bounds ahead of other GBBR systems as it comes out of the box, and Double Eagle has added even more improvements on behalf of EMG, including steel trigger group components. 

A GBBR is the perfect platform for the AEG user who is getting bored of that sewing machine sound, lack of recoil and unrealistic capacity magazines. With a GBBR, you are treated to the highest levels of realism Airsoft can offer; with realistic-looking internals, perfect 1:1 dimensions, shoulder-thumping recoil you have to work to control and realistic capacity magazines which require the charging handle to be pulled or the bolt catch slapped to bring the rifle online after a reload. 

Nothing beats the satisfaction of bagging a kill with a GBBR, though it doesn't come without challenges. With a gas power source and low-cap magazines, you will have to choose your shots and when it comes time to reload, showcase your handling skills. If you're the type of player who gets a kick out of working hard like the real warriors do, you'll love a GBBR!

Starting at the front, we can find a three-prong Sandman KeyMo style flash hider, giving the N4 a sleek and modern look. Give the flash hider a tap and listen to that ring...that's how we know it's made from steel! While the three-prong looks fantastic on the N4, the barrel features 14mm CCW male threading so you can add an alternative muzzle device of your choice, including tracer units and suppressors. 

The barrel is finished in matt silver, matching the real N4 series of rifles and giving the Double Eagle GBBR a bit of tasteful contrast while not being too garish or ruining your concealment efforts in a woodland environment. The barrel is visible through the handguard ports, along with a detailed dummy gas block and gas tube which is the correct length for the real steel N4 10.5" Shorty platform. Nothing ties a replica together like flawless details, and Double Eagle has smashed it with this one!

The handguard itself is a replica of the real steel Noveske NSR 9, equipped with M-LOK negative space attachment slots at the 3, 6 and 9 o'clock positions with a 20mm Picatinny rail along the top. The M-LOK slots are punctuated by the recognisable NSR style elongated vents, reducing overall weight and adding to the gripping qualities of the handguard when run slick without rail covers. Being an EMG-licenced replica, the handguard sports Noveske trademarks at the base, reading "NSR-9" with "NOVESKE.COM" beneath. These markings are absolutely immaculately engraved and look phenomenal; especially impressive considering the thick, hard-wearing finish which would usually obscure details like this.

As we reach the receiver we can take note of the familiar and well-placed M4/AR-15 controls, though the receiver itself is a little different to the standard AR. The upper receiver is patterned after the Noveske Gen.3 upper receiver, matching the real thing perfectly with all the correct angles and shapes, a prominent "NOVESKE" engraving on the left side, a Noveske logo on the forward assist and a reprofiled mock forward assist and brass deflector bulge, intended to reduce snagging potential. The lower receiver is a standard M4/AR-15 receiver but with Noveske markings on the magazine well, body pins, and just aft of the mock bolt catch. Plenty of trademarks on this beast, perfect for realism fans!

The fire selector switch is right where we would expect it on the left side of the receiver, just above the pistol grip. Offering 3 modes of fire with a 90-degree throw between each, the selector is one of the highlights of the AR platform; secure enough to avoid inadvertent mode changes but fast enough to play "sights off, safety off". The available firemodes are SAFE, SEMI and AUTO, marked with engravings in classic M4/AR-15 style. 

The magazine release catch can be found on the right side of the magazine well, lying well within reach of the trigger finger for super slick and easy fast reloads. The mag release is a push-button design and can be replaced with an aftermarket ambidextrous magazine release if required. On the left side of the receiver, we can find the mock bolt catch, taking the form of the classic M4/AR-15 "ping pong paddle". This catch allows you to release the bolt after a reload, speeding things up by removing the charging handle from the reload process. Both the mag release and bolt catch are constructed from steel which is very important for a GBBR as these high wear parts tend to be the first to fail. Using steel here saves you money on essential upgrades down the line. Nice one Double Eagle!

At the top rear of the receiver, we can find the ambidextrous charging handle, known by Noveske as the "Super Badass" charging handle. The handle has an ergonomic textured latch on either side, providing intuitive handling for both left and right-handed shooters. The charging handle needs to be pulled to load the first BB, but make sure the fire selector is set to the "SEMI" position before pulling the charging handle to avoid damaging the selector/trigger mech. With the charging handle pulled back, you will see even more Noveske markings on the handle stem itself!

The HOP-up unit of the EMG/Double Eagle Noveske N4 GBBR is located inside the upper receiver, following the Tokyo Marui ZET system format. Taking the form of a small gear inside the front of the upper receiver, the HOP-up adjustment dial is accessible through the ejection port if you have small fingers or a fine tool. The easiest way we found to adjust is by field stripping the rifle and accessing the dial with the bolt carrier and charging handle removed. The HOP-up allows you to tune the N4 Shorty for different ammo weights and extend your range, looking for the flattest possible trajectory. 

The bolt carrier itself is finished in the same matt silver as the outer barrel, visible when the dust cover is open and adding a nice bit of visual interest to the design. The dust cover also has very clear .300 BLK markings on both the inside and out, a feature derived from the real thing and intended to avoid the potential of accidentally loading a 5.56mm cartridge into the rifle. The consequences of this would be disastrous, but lucky for us our guns are all chambered in 6mm!

The trigger guard is enlarged to allow for full-fingered glove use and boasts a Noveske logo on the bottom, bringing it into line with the rest of the design. To match the real thing, an ergonomic Noveske grip is fitted with a refined grip angle intended to reduce wrist fatigue when shooting with the stock fully collapsed. The grip has a filled-out back strap and linear texture on the front and rear along with dot texture on the flanks, providing ample grip for wet weather operations and a super comfy grip you will never need to change. 

Bringing up the rear we have the good old M4/AR-15 buffer tube, featuring a steel castle nut to keep it firmly mounted. The buffer tube itself allows for 6 positions of adjustment, allowing you to set the TS2 style stock in the perfect place to suit your body type and loadout.

The pre-installed stock is a TS2 style stock, featuring a well-concealed low-profile adjustment lever, and two QD sling sockets on either side. The stock also features an additional conventional sling slot for those who prefer the old ways. The stock attaches to a standard AR15/M4 6-position buffer tube, which allows any aftermarket stock to be added if you fancy a change of pace. The QD sling sockets are present on either side, with one at the front of the stock and one at the toe; giving you the option to add an aftermarket front sling point and a QD sling swivel to run a two-point sling. As part of its low-profile, snag-reducing design, the adjustment lever of the TS2 is a trigger-style button inside the toe of the stock, well out of the way of potential snags so you can stay fleet-footed, even when all geared up. 

On the inside, the EMG Noveske N4 has some surprises in store. The trigger group parts are all constructed from steel, meaning you won't have to spend hundreds on steel trigger parts later in the platform's life to keep it running. The bolt catch is also steel, guaranteeing reliable bolt locking at the end of each magazine for a realistic experience that will last in the long term. 

The design of the TM ZET system itself is very resistant to wear, unlike previously conceived GBBR systems. The aftermarket for the ZET system is also constantly growing, meaning you have access to the latest GBBR internal parts and the most up-to-date upgrades to keep the N4 at the bleeding edge of GBBR performance. As far as compatibility goes, the ZET system uses unbridged VSR/GBB inner barrels and VSR/GBB HOP-up rubbers, so if you want more range and accuracy out of this beast you have access to the exceptional Maple Leaf Crazy Jet, TNT S+ and Laylax Prometheus tightbore inner barrels, just like the VSR-10 sniper rifle platform. 

If you think you're ready to move up to a GBBR platform, the EMG Noveske N4 is absolutely the best place to start. With superb internals based on the TM ZET system but with added steel trigger parts for a longer life, the N4 GBBR gives you access to the widest GBBR parts aftermarket and the most efficient GBBR system in a gorgeous external body littered with licenced Noveske trademarks.

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". Do not force the selector into "Safe" when the rifle isn't cocked; this will damage the trigger group parts. 
  • The HOP-up adjuster for this TM ZET system GBBR is inside the upper receiver and is accessible through the ejection port, or with the rifle in field stripped condition.
  • 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.
