Great gun for great value. I’ve never looked back. Perfect for beginners and seasoned veterans alike!

To get the ball rolling, let’s start with a summary of the gun.

As the title suggests, this gun is manufactured by G&G Armament and is one of their Top Tech line; it’s also a first generation Top Tech model. You might have seen an article that we posted earlier in the week about G&G’s Third Generation Top Tech rifles now being available, and that’s what’s going to make this review so interesting. Finish reading how good this thing is and you’ll be set on a Gen3 Top Tech gun before your wallet can even think of saying no, let alone say it! …What’s that? Wallet’s can’t talk? …Doctor?!

As this is the A4 version of the MP5 you can expect to see a full rifle stock; MP5s can often have their battery in the handguard, but with this version, since the space is available, the battery is housed in the stock. When I say, “housed” I’m not exaggerating either, you could live in this space it’s so massive! If you find a battery that doesn’t fit in there, I’ll be lost for words in amazement. I run mine with a 3700mah 8.4v NiHm type battery, which can last me more than an entire weekend of use, and I’ve left the connectors as they come out of the box – using the large Tamiya type plug.

The version of the gun that I have is the metal one; this gives me a metal outer barrel and gas system assembly, cocking handle and upper receiver. Leaving the lower receiver, stock and both forward handguard and pistol grip to be made of reinforced nylon fibre, as per G&G’s cheaper, but certainly no worse, “Combat Machine” range.

Something worth considering is that since the parts you hold are all plastic, you could be just as well off buying the plastic version of the gun, since it will feel no different to your hands when you’re manipulating it. The plastic version, as with any airsoft gun, is generally around £70 to £100 cheaper depending on where you buy it from. I bought mine from Landwarrior for £220 way back in June of 2011 but the plastic – or rather, reinforced nylon fibre – versions are sold for around the £130 mark and can deal with the same level of punishment and still have the same internals and a metal outer barrel. So if you can sacrifice that realistic weight, you might as well do so and save your wallet a little heartache.

The fps? Out of the box you can expect feet per second readings of between 310 and 330 with a .20g BB, which is ideal for most UK CQB fields, which is most definitely where this beast shines.
How’s the hop? Adjustable hop as standard, using G&G’s fantastic “weather resistant” Green hop bucking, and as to be expected the adjustment arm is located inside the ejection port; which can be locked open using the charging handle, as well as being able to “slap” it back down for that authentic Heckler and Koch feel.

The hop is an incredibly effective design and the green rubber is capable of some truly impressive lift, I tested mine with up to .40g BBs and was still able to engage targets accurately at up to around 25m before the BBs lost their momentum and started dropping.
Any neat features? The gun comes utilising G&G’s very smart pneumatic blowback engine. Blowback you say? Isn’t that a gimmick? Well, not in G&G’s Top Tech guns. In most blowback AEGs the external bolt that you see moving back and forth is clamped directly to the gun’s piston, inside the gearbox. This famously causes a huge amount of excess strain on the gears, piston and the motor and can cause your gun to die a little sooner than it otherwise would. Leading many to now see blowback as added hassle they don’t need, most people will simply disable the blowback as soon as they get the gun, to give them that faster response from the trigger, and the peace of mind that their piston won’t strip if they catch the bolt on something in the middle of a game.

Well, with the pneumatic system, all that hassle is over. Instead of the bolt being clamped to the piston, it is left to freely move back and forth along a set of runners, with a spring to pull it back to the forward position. The way it is “blown back” is by residual air left over once the BB has been fired. So it’s sort of similar to how a real gun’s blowback mechanism operates. Excess air not needed in the propulsion of the BB is redirected into a second air canal above the gearbox and is then used to push the bolt back. The result is a very snappy blowback action, with a great sound to it and none of the gearbox mashing melodies of the blowback of old, that everyone has grown to detest.

So you know what to expect out of the box when you pick one of these babies up, but you’re still none the wiser about how it performs in a skirmish situation:

Well, you may remember me mentioning the Gen3 Top Tech guns now being available way back up at the top of the review. The reason I brought that up is because they come fitted with tight bore barrels and active braking mosfets right out of the box, which are generally the sort of things people will spend a lot of time and money upgrading themselves. Being old, this humble Gen1 MP5 doesn’t come with any of those, you’re just left with all the standard components you’d expect an AEG to come with, except it’s made by G&G and branded as a Top Tech model that’s all that’s really special about it if you were to compare it with any other AEG – on paper.

In practice, this gun is spectacularly accurate, has very snappy trigger response and is the only gun I’ve owned to date that I haven’t felt the need to upgrade, and if you know me, you’ll know how bold of me it is, to make that statement. The gun is just that good. I can scarcely imagine how spectacular the Gen3 guns must be!

Don’t believe the performance is as good as I say? Take a look at the video from my YouTube channel.
