The Heckler & Koch MP5 is a classic modern firearm that you'll see in almost every special operation movies. It's always fun to watch special operators using it. And it's always exciting touse in the Tom Clancy's Rainbow Six video games on the PC The MP5 comes in a number of variants. The JG M5-A5 is the standard MP5 replica with a retractable shoulder stock. The photo below shows the airsoft replica of the MP5.
Although the model name seems to indicate that it is a replica of the of the MP5-A5, it is actually not the case. If you refer to the Wikipedia page on the Heckler & Koch MP5, you'll see that it is, technically, a replica of the 'MP5A3: Retractable buttstock,"SEF" trigger group.' That is because the MP5A5 has 3-round burst trigger group, which this airsoft replica does not have.
The JG M5-A5 airsoft gun comes in a nice cardboard box as shown in the photo below. A huge blank sticker is pasted onto the left side. It's pretty much impossible to peel off the sticker without destroying the box. I suspect that it is covering a trademark that it infringed upon.
What's surprising is the big "M5-J" designation. No where in the box does it show "M5-A5".
Upon opening the box, you can see that the MP5 airsoft gun is nicely packed in the photo below. All of the accessories are in boxes.
After unpacking the gun and the accessories, we see, in the photo below, the package includes MP5 gun, MP5 high-cap magazine, instruction manual, cleaning rod, a bag of BB's, 8.4v battery, and charger.
The photo below shows the specification for these accessories. The AC/DC adapter model JG-TY02 provides 8.4v with a maximum current of 250mA. This AC adapter is for 8.4v batteries. It's not clear whether it can charge 7.2v batteries or not. I suggest you don't take a chance on that.
The included 8.4v battery pack provides 1100 mAh of capacity. The included BB is 0.2g, but really is not enough for it to be much use.
The instruction manual seems to be very high quality. It even have two detailed parts diagrams. It includes Japanese and English instructions with sporadic Chinese. It seems that this airsoft gun is intended for the Japanese market, which is always a good sign of high quality product.
The JG M5-S6 is mainly made out of polymer (plastic). However, it really feels sturdy in my hands. If I have not known that it was plastic beforehand, without examining the gun, I would have thought that it might be made out of metal. In fact, the weight of the JG M5-A5 is quite heavy for a gun that is made out of plastic. Perhaps it is because it contains numerous metal parts.
The left side of the receiver has the mode selector switch. It provide three modes: safe, semi-auto, and full automatic. The bright red shows excellent contrast against the black receiver. But I wonder how easy it is for the enemy to spot on the battlefield. You can also see a sling attachment forward of the receiver.
The right side of the receiver, shown below, has the same mode selector switch. This airsoft gun provide ambidextrous support. A warning label show the following message:
The magazine eject switch is right in front of the trigger guard. In addition, there is magazine release on the right side of the receiver, much like the M4 carbine. The magazine release on the right side springs back. But the magazine release on the front of the trigger guard doesn't. I'm not sure if it is suppose to or not.
The JG M5-A5 comes with an orange barrel cap (see photo below). It's bright orange. That's a good thing, because I will paint the orange tip black, but I like to use an orange cap when I store and transport the airsoft gun.
Dis-assembly instructions for the JG M5-S6 is in this article: "How To Disassemble a MP5 Airsoft Submachine Gun".
The photo below shows the hop-up lever on the JG M5-A5. It's between the handguard and the barrel. It's easy to miss if you are not looking for it. The hop-up is increased when you move the level backward. It's decreased when you move the level forward.
The telescopic shoulder stock has five positions, biased toward the long end (four positions are at the long end).
The battery compartment is located within the handguard. To remove the handguard, you have to push the pin, toward the front of the handguard, out. The pin is right behind the sling mount as shown in the photo below). Once the pin is removed, you can rotate the handguard downward and remove it..
Although a 8.4v battery pack is included, it barely fits in the battery bay. In fact, I do not suggest you use it, because the battery pack is too big and will push against the inner barrel, which is made out of soft brass (see photo below). I found the butterfly (or the nunchucks) battery packs works great in this battery compartment and suggest you use one of those.
Looking through the magazine well, the JG M5-S6 has a black plastic hop-up and a black metal gearbox.
The MP5 magazine for the JG M5-S6 airsoft gun uses the same MP5 magazine for the Tokyo Marui airsoft guns. Therefore, it should be interchangeable among other Tokyo Marui MP5 clones.
I happen to have both the high-cap and the low-cap magazines. They look identical in the photo below. Of course, the high-cap has a winding wheel on the bottom and the BB loading opening on top.
The photo below shows the top of the high capacity magazine.
It opens and allows you to load lots of BB's, see photo below.
The winding wheel is below the magazine as shown in the photo below. The MP5 magazine winding wheel is much wider, but much smaller than the M4 magazine.
If you want to remove the plastic magazine insert, you'll have to tap out the pin at the top of the magazine (see photo below).
The JG M5-A5 performs extremely well in CQB environment. It is very small and compact when the shoulder stock is retracted. Therefore, it's perfect for maneuvering in small CQB fields. This gun is now part of my loadout for CQB fields.
It shoots consistently at 380 FPS, meaning it is competitive on big fields. But you may have problem using it at smaller CQB fields that has a 350 FPS (TacCity) or 365 FPS (Insight Interactive) limit.
The magazine sits nice and snug, providing no problem whatsoever. The safety switch is harder to rotate than other airsoft guns I've used. It provide a strong click for good tactile feedback. I rarely extends the shoulder stock in a CQB environment, but it could be really useful on a big airsoft battlefield.
