The Heckler & Koch MP5 is one of my favorite guns. It shows up in almost every covert operation movies. And it's always exciting to watch. The MP5 comes in a number of variants. My favorite is the silenced version, which probably won my heart in the Tom Clancy's Rainbow Six video games on the PC. So once I have gotten into airsoft, naturally, I have wanted the JG M5-S6 silenced MP5 airsoft gun. But, due to one thing or another, I never have gotten the JG M5-S6 until recently. The photo below shows the airsoft replica of the silenced MP5.
Although the name seems to indicate that it is a replica of the of the MP5-SD6, 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 'MP5SD3: Retractable buttstock, "SEF" trigger group, integrated suppressor.' That is because the MP5SD6 has 3-round burst trigger group, which this airsoft replica does not have.
The JG M5-S6 airsoft gun comes in a nice cardboard box as shown in the photo below. A huge 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.
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 high-cap magazine, instruction manual, a bag of BB's, 8.4v battery, and charger. What is not shown in the photo below is the silenced MP5 and the airsoft cleaning rod, which are also included.
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 only problem? The instruction manual is for the vanilla MP5. It doesn't show the silenced MP5.
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-S6 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, shown below, 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-S6 comes with a silencer barrel cap (see photo below). It's bright orange. That's a good thing, because I like to use an orange tip when I store and transport the airsoft gun.
The silencer also has a bright glossy orange tip (see photo below). So far I have been unable to remove the orange tip, nor the silencer. It's looking like I will have to paint this orange tip black while it is attached to the gun. Luckily the provide orange cap will provide the orange color that I need for storage and transportation.
The photo below shows the hop-up lever on the JG M5-S6. 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.
It's hard to notice if you aren't looking for it, but there are a number of metal external parts on the JG M5-S6. For example, the telescopic shoulder stock has metal rails, all sling attachment points are metal, iron sights are metal, magazine release button is metal, and the high-cap magazine is metal.
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 slide the handguard forward, you have to remove the two pins on either side of the handguard. Once the pins are removed, you can twist the handguard and push it forward (see photo below).
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.
With a flashlight, I looked down the silencer. Yes, I know I'm not suppose to do that. But I ensured that the battery is not plugged in and the magazine is out. I can see that the inner barrel does not go through the entire length of the silencer.
That's two strikes on the inner barrel--being brass and is not full length. It seems that a standard 363mm inner barrel would fit wonderfully in this airsoft gun. I would get a tightbore stainless steel barrel to replace the stock barrel.
Dis-assembly instructions for the JG M5-S6 is in this article: "How To Disassemble a MP5 Airsoft Submachine Gun".
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-S6 performs well in CQB environment. It is small and compact when the shoulder stock is retracted. But its silencer makes it longer than its plain vanilla MP5 siblings. In extremely small CQB environments, where the buildings are much smaller than real-size, it's hard not to extend the mock silencer out the window. Nevertheless, it is still great for maneuvering in small CQB fields. This gun is now part of my loadout for CQB fields.
It shoots consistently at 350 FPS, meaning it is competitive at most CQB fields, even ones with strict, low FPS limits (350 FPS at TacCity).
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.
