G&G has stepped up their premium gun game with a lot of new features which this blog is going to list and break down, first covering the externals and build, and then the internals, as well as other cool features, many of which are even more than one would have asked for from premium airsoft guns.

Externals & Build

This gun belongs to the G&G G2 series, and is known as the TR16 MBR 556 WH G2, but let’s call it the G2 for short. It’s clear that the Mechbox is what you’ve been waiting for, even though we did a sneak peak almost a year ago. Externally, this gun is pretty neat. We’re going to describe it from the inward portion of the cover and work our way down. One will notice a cool flash hider on the cover, along with a very long outer barrel that is pretty similar to a DMR. Although it is not a 762, there is 556 gas tube under there, further displaying that this is a really high-end, premium gun. It is definitely up there with the Krytac’s, the VFC’s, the Avalon’s and other high end guns.

G&G have really outdone themselves with the rail, as it is honestly beautiful. You’ll notice its amazing matter finish, as well as how nice the aluminum looks and feels. There are many attachment points to ensure that there is no wobbling. An M lock is present which locks all the way up and all the way down to the bottom, as well as all the way up and down the sides. They even included Pica-tinny rail segments across the top on the rail, not just the receiver. They essentially hollowed them out by carving, adding cool, extra details to get excited about, and which set their rail apart from any of their competitors, essentially presenting a new G&G rail. There is also a flip-up front and rear metal sides, as well as a fully metal body, both upper and lower. It is fully ambidextrous on the fire control, making it safe on both the semi and fully automatic burst for a time.

We’ll describe this first feature further when we cover the internals and the mag release and functioning bolt lock. The bolt lock is not ambidextrous, but this isn’t generally used very often in any case. This allows one to pull it back and lock it in, with the bolt being locked back in place and revealing the rotary style hop-up which you would expect in a premium gun. In fact, we’d be pretty shocked if they hadn’t included it in this gun. As a result, the release slams the little fake bolt forward. When the charging handle is pulled back, one can see G&G logo there in white, with a pretty short travel distance. It’s the ambidextrous kind, i.e. both sides. The new G&G stock has actual twist-to-side battery exposure, so when one kind of presses down the button and twists the pad, it lets them get inside and make the changes. This is also where the MOSFET is present, which we’ll cover in the internals section. Essentially, one twists it back, meaning they won’t have a button cap that’s going to fall off and going to get lost. There is also a big rubber pad, which isn’t needed for recoil but makes it more comfortable, as well as some storage space here for batteries and other small accessories.

The actual stock locks itself into place so that one kind of has to break that lock and then they can slide it pretty easily. From there, one finds where they want and then they can snap it back again without it going anywhere. Since it is locked, there is no accidental stock retracting when one is trying to take that good shot. There is also a sling attachment plate, two on one side, one on the other, so that if one wants to do a single point sling double they’re able to. Although, if they’re going to, they will need to put something up there in the front even though it is in lock, and one can pick up such lock accessories anywhere for this gun. The grip itself has finger grooves hiding the motor underneath like the usual motor adjustment. In this case it is a flathead, which is very useful since it is recessed, as opposed to a large screw. There is also a smaller screw near there as well as in the magazine.

The magazine itself has a little follower that kind of looks like it’s broken and kind of droops around. As one would imagine, it feeds every single BB out, and has a 90 rounder that comes with it. The 90 round midcaps, of course, means that we’re describing a premium gun and so it is to be expected, unlike high counts when one moves up to a level gun like this which feeds every single BB. Another neat feature is a small button which will not fire with the mag out, rather one has to have the battery in, take the magazine out and then pull the trigger. Nothing will happen with that, and this works with any magazine, including the one we mentioned as well as M4 mags, PTSP mags or even EPM’s. Regardless of if one wants to use any midcap or highcap out there, they will be able to do so. They simply run it, and when they pull it out it will stop firing.

This one also has an additional feature for when it runs out of BBs and stops firing, which are special mags from G&G that aren’t necessary but are nice to have, since the 90 round midcaps have that nice of kind fall that won’t break. If one has ever had them where they feed all the BBs out, then they will know that when the little piece pops up, and they forget to push it back down or something along those lines, it ends up snapping off every single time. However, in the case of this model, there is a much lower chance of something like this happening. This wraps up the externals, meaning it is time to cover the internals.

The Internals

As for the Internals, there is where the epic G2 Mechbox is going to shine, and really show that there is a lot going on under the hood. Some of the components of the Mechbox that are different have been upgraded for other ones, and there are many new electronic features. First off, they have upgraded the Mechbox components, adding a new bevel gear, which is essentially a gear on the motor known as the pinion gear. When it is inside of the Mechbox it is called the bevel gear and it is essentially where a lot of the noise, whining specifically, will start to happen, and then will be heard mostly by the next gear. The bevel gear here has been redesigned in order to lower noise and friction, which in turn results in less power usage and voltage when one pulls the trigger on startup, as well as a longer battery life and more shots per battery charge.

As for other parts on the inside that have been changed, the cylinder head and air nozzle are both now double O-ring, meaning there is a double seal on those that have a single O-ring and which will result in better compression components, meaning that the air will be kept nicely in there. One wants all this air to go up the barrel and not to be lost with leaks around the nozzle or cylinder head when they come in contact. This double O-ring essentially seals the area up better and provides a second line of defense, meaning less air lost and as such more power down the barrel and more accuracy as well as efficiency.

The G2 has an ETU, i.e. an electronic trigger system, in MOSFET Combo. The MOSFET is present in the back and is now 50% smaller than what one would find on their regular ETU gun. Features that we’ve wanted for a while have been added as well such as a small speaker which provides audio to the user to give them information on how they’ve programmed it, such as three round burst or five round burst, also meaning that the gun can do both. The audible tones also mean no more vibration or guesswork is needed to know if one has set it correctly or to know how many times they’ve pulled the trigger. Every time a setting is changed, a sound will be heard, including if the battery is low, for example, which will result in constant beeping. In this case, if one is running a lipo, which they should be if they are using this gun, it is going to monitor the battery when it is low

and let the user know it is time to stop shooting, swap it out and get back to the game. It will also point out any mechanical failure such as if the trigger is pulled and isn’t working quite right. All of these useful features have been built into the new electric trigger system and the MOSFET system.

Another feature one would expect on a gun of this caliber is the quick change spring system. Although it needs to be taken out of the box and it cannot be accessed, which is standard procedure, one will at least not need to take apart the Mechbox for any internal power changes, providing additional convenience. As mentioned earlier, the way the bevel gear meets with the pinion gear has to do with the way the motor enters in from the grip and enters the body of the Mechbox shell, meeting up with the bevel. [MOODY] One of the wires runs right past this point, which has been given a wire cover in order to ensure it doesn’t get chewed up. Although it is not that common, it has happened in my many years of playing where its either gotten chewed up or it has happened while working on the gun and pulling the motor in and out which caused a problem that resulted in a short-circuit and a big mess. Although this is a small detail that has been added that one wouldn’t normally think about, it makes sense that a gun of this calibre would have it, since it is top of the tier and the apex predator so to speak of airsoft guns, and is right up there with the other high-end ranges of other companies. This feature is something one would expect, and that I was very glad to see added. The coverage, as well as the bevel gear change, really demonstrate the kind of detail put into these guns to show their owners that the company worries about them for a long time to come and not just at the time of the purchase of the gun.

Chrono Test

Finally, we get to the Chrono Test. The numbers were very good, and the rate of fire was extremely impressive. It is an 11.1 lipo, with a motor that is extremely powerful, giving off almost 1500 rounds per second. It is basically humming BBs out. The gun is semi-automatic, and one will feel it when they pull the trigger. This gun is different than the plenty of G&G ETU guns I have fired, really showing just how premium this fun is. I simply pull the trigger and can feel just how different it is, especially after having seen the Mechbox up close. This isn’t some sort of sales pitch, but is my honest conviction. If you’ve always thought of the G&G for beginner guns like the Raider, you should really take a look at their new high end line and I am sure it will leave you surprised. Have your shop put a battery inside of one and simply fire off a few rounds at Chrono line and you will feel what we’ve been describing. You can’t quite tell until you pick it up and pull the trigger, and that is when you will feel the way it fires and how it cycles, as well as how smooth it is. Only then will you really get a feel of just how much is going on under the hood with this extra reinforcement box.
