Description
If you need a high-performance AEG capable of slapping opponents at range, the G&G Armament TR16 GMS MK.II GT Advanced G2 M4/AR-15 AEG should be at the top of your list! This rifle comes with performance and reliability-focused upgrades, such as its reinforced V2 gearbox.
Beginning at the front of this platform, we can find a steel flash hider. This matches the style of the rest of the rifle perfectly and leans into the tactical style. However, if you don't like it or prefer an alternative, you will be happy to know that it can be removed to reveal 14mm CCW threading (just remember to undo the flash hider's grubscrew first). With it removed, you can mount a muzzle device of your choice, such as a tracer unit or suppressor.
Moving rearwards, we reach the aluminium M-LOK handguard. This boasts M-LOK attachment slots on the 3, 6 and 9 o'clock positions, and short sections of Picatinny rail at the front of each. Up top, there is a 20mm Picatinny rail that runs back to the 20mm railed receiver, creating a long section of attachment space for any manner of optic setup.
Sitting atop the Picatinny rail is a pair of preinstalled iron sights. These boast G&G's most recent iron sight design, a combination sight which offers a light-enhancing open sight when flipped down or an adjustable aperture sight when flipped up. The front light-enhancing insert is red, and the rear inserts are green, ensuring you never mix up the sight index points when shooting pumped with adrenaline. When raised, the aperture sights can be adjusted for windage and elevation without tools via the drum on the right side of the rear sight and in the centre of the front sight.
The handguard has QD sling sockets on either side, at the front and the rear. These sockets are functional with traditional QD points. This is perfect for setting up a two-point sling to help carry the rifle around the battlefield. Just above the QD points, there are G&G trademarks along with others.
As we come to the receiver of the G&G Armament TR16 GMS MK.II GT, you will notice the familiarity of the M4/AR-15 style layout, making it an easy transition in terms of training if you're already accustomed to running an AR platform in-game. The charging handle has an extended design, positioned at the top rear of the receiver, which can be pulled back to lock the mock bolt carrier back. To release the mock bolt carrier, hit the "ping pong paddle" style bolt release on the centre left of the receiver and enjoy the satisfying metal-on-metal clank of it closing!
The fire selector features the standard M4/AR-15 layout, but is ambidextrous, with a 3-position selector switch located on both sides above the pistol grip, offering safe, semi-automatic, and full-automatic modes. The selector has a 90-degree throw between each fire mode, allowing the control to be used swiftly while minimising the chances of accidentally knocking the selector out of place. Being equipped with the GATE ASTER ETU, these fire modes can be programmed with alternatives, from burst mode to binary trigger and more!
The pistol grip has a unique G&G design, boasting a grippy external surface, a low-profile palm rest that reduces wrist fatigue when shooting with modern techniques. With its unique style and pattern, it's perfect for gripping in all weather conditions. Although it is a great design, the grip can be swapped out for any M4/AR-15 AEG pistol grip, an ideal feature for the customisation addicts!
At the rear of the receiver, we're equipped with the standard M4/AR-15 buffer tube, a 6-position example made from alloy, allowing the pre-installed GOS-V15 sliding stock to be adjusted to suit any body type or loadout. Just in front of the buffer tube, we're treated to an ambidextrous sling plate made from steel, ideally suited to conventional slings and those equipped with an HK hook. As it is made from steel, this sling point is easily sturdy enough to support the weight of the rifle, even when decked out with accessories.
The GOS-V15 sliding stock is one of the highlights of the build, a fantastic-looking stock design combining many convenient features of the best AR-15 sliding stocks in the real steel world. The adjustment lever of the GOS-V15 is a low-profile example inspired by the real steel MOE-SLS stock, allowing for easy adjustments while keeping the lever clear of snags and obstructions.
On each side, the GOS-V15 features steel QD sling sockets, ready for QD sling swivels to be added to mount an ultra-modern, quick-removable sling setup. The butt plate is serrated and made from grippy rubber for maximum wet-weather traction, and the cheek pieces are comfortably sloped similarly to the legendary Crane stock, though they are much slimmer to promote in-game agility and reduce equipment snags.
The battery compartment is inside the buffer tube and accessible through the rear of the GOS-V15 stock. To access the compartment, simply press the tab on the top of the butt plate and rotate it by 90 degrees in either direction. Inside the buffer tube, you'll find a mini-Tamiya battery connector to which you connect your choice of battery. We recommend an 11.1V 1450mAh Stock Tube Battery for an easy fit and solid performance.
On the inside, the G&G Armament TR16 GMS MK.II GT pairs 8mm ball bearing bushings with a 25,000 RPM high-speed motor and a new G&G reinforced gearbox. It keeps the replica performing well and reliably. G&G rifles are well regarded for their solid internal parts, which perform consistently even after many game days.
The highlight of this platform is its GATE ASTER MOSFET/ETU, which provides superior electrical efficiency, protects your battery from reverse polarity and has a whole host of advanced smart functions. They can be unlocked by using the Gate Control Station app, the Gate Blu-link, the Gate USB-link or the Gate Programming card (available separately).
In conclusion, this rifle is seriously impressive. The tactical style, paired with the G&G craftsmanship and the preinstalled GATE ASTER ETU, is the cherry on top. If you need an outdoor primary and want something that is ready straight out of the box, the G&G Armament TR16 GMS MK.II GT Advanced G2 M4/AR-15 AEG is an excellent choice!

Joule Charts
Special Instructions
These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.
FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.
Tap the tabs below to open the relevant chart for your replica.
This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.
In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.
Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.
Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
