GB MP5A4 Echo Electric Rifle Manual

This is an exact copy of the Tokyo Marui MP5. In our opionion, up to this point, this is the highest quality airsoft AEG / MPEG to come out of China. JG continues to put out the highest quality products, setting it far ahead of many of the other manufactures in China. Keep an eye out for this model along with others by JG.

What is JG or GB or Echo1?
JG stands for Jing Gong, which is actually Chinese for Golden Bow; hence GB. Also, Echo 1 is the same as GB or JG, they are OEM Jing Gong airsoft AEG guns. All these different names for the same airsoft manufacturer is confusing. Hopefully, this has helped clairfy the confusion.

Review by Nick Petrus from USASOC

While waiting for the MPEG to arrive, I checked into the gun. I had my doubts from what I heard from different people, but they were blown away when I received it. When UPS arrived at my front door, I was excited to see what AirSplat sent me. The packaging inside the box was great, and nothing was damaged at all. My first impression of the MP5-SD6’s (Yes, I know it says “M5-S6” on the box, but it’s really modeled after the MP5-SD) box was, “Wow!” For $79.99, I was impressed. The box was very durable and was not falling apart – a good sign that nothing will be broken before you even use the gun. Now as you can see in the picture above and below, the box doesn’t have any fancy designs on or in it, but that doesn’t matter to me. What matters to me is what is actually inside and how well it is packaged.

So I opened up the box and was again impressed. Everything was tightly packed and secured – a good sign. I then began looking at everything that was included. There was the actual MP5-SD6 itself, a battery and charger (nice for newer players), the magazine, the BB loader, and the cleaning rod along with the manual and small bag of .2 BBs. Again, for $79.99, (Although free for us thanks to AirSplat), you get the complete package. There is no need to worry about buying a charger and battery, which I think is great for newcomers of the sport.

Look and Feel:

The overall look of the MP5-SD6 is very good. It has a nice black finish to it. The silencer is painted orange at the end, of course due to federal laws. The magazine is metal (a plus!) with a good part of the gun being metal as well. Most of the external body is plastic which may cause some of you to wince at, but it is a MPEG. The handgrip is excellent; it has a nice feel to it, and the design is great as well. The silencer can be unscrewed to reveal the barrel - again metal. The retractable stock is plastic, but has a comfortable feel to it. It has two modes: all the way inward and all the way extended. Most people prefer the extended, which is also my preference. There are two fire modes: single and full auto. There, of course, is a safe mode as well. The rear sight is adjustable, as with the hop-up in this gun. Some have said that they have had trouble with the hop-up, but so far we haven’t nor plan to. For a MPEG, the MP5-SD6 is relatively heavy. I thought that because it is a mid-range AEG, it would be made all of plastic and thus, be very light, but not so at all.

Battery:

One of the features that I thought was great was that a battery and charger are supplied with the gun. For people new to the sport or people who can’t spend $200.00+ on a Classic Army, Tokyo Marui, etc, this is a wonderful feature! Even to an experience airsofter like myself, I thought it was excellent benefit. Now the charger isn’t a high-speed, high-tech charger, but it does get the job done very efficiently. The only trouble I had with the MP5-SD6 was putting the battery in the gun. To me, it seems that all airsoft companies that make AEGs should come up with a better way to place the battery in the gun, but since I don’t make the guns, I shouldn’t be complaining. The proper way to place the battery in the gun is as follows: one, remove the two little pin-like items on each side of the handgrip (Photo of Battery #1), and two, simply pull the handgrip forward and off the gun (Photo of Battery #2). It’s as simple as that! Some of you may be wondering why I had such a hard time figuring that out. Well, whoever packed the box at the manufacture’s warehouse in China made a mistake putting the wrong manual in the box. I received the manual for the MP5-J model, not the MP5-SD6 model. However, the guns are very similar so it didn’t take much to figure out all the features. The wiring for the battery is great. Most of you may not agree, but I dare to say that the wiring for this gun’s battery is more organized and secure then Classic Army’s and other brands, but that’s just me.

Performance:

For $79.99, the accuracy and FPS on this AEG are great! The FPS is around 290-330 FPS. It has a range of around 200-250 feet. I was a little worried that the accuracy would be off, but it really hasn’t been. There were a few rounds that went way left, but the wind was blowing at the time. Also, the gearbox is a version two and is metal - a great plus.

Pros:

The following are the pros about the gun: the look, the quality for its price, the battery and charger included, a good part of the gun being metal, the price, the accuracy, and that it’s a great player package for newer-middle class players.

Cons:

There are very few things that I found wrong with the gun, but there were still a few. One was that the switch for the fire mode is a little flimsy, but not bad overall compared to what I’ve seen out there. Two, I had, and still have, a little trouble with the magazine. It seems that when it locks into place, the gun has trouble firing them, yet while I apply upward pressure to the magazine, every BB fired. So it seems to me that it doesn’t fully lock into place, thus requiring you to slightly push up on the magazine. Again, not a big thing, but it can get annoying after awhile. Yet I haven’t heard about people having trouble with the magazine so it could just be me. Third, if I was to be picky, I would have to say that the stock only has two modes: fully inward and fully extended. And fourth, is that the gun is noncompatible with other magazines, that we know of. The best thing to do is to email wherever you are buying the gun from and ask; they should know.

Overall, I really couldn’t be happier with this gun for its price. I’m extremely impressed with its look, price, accuracy, etc! For $79.99, it’s a great deal for newer to middle class players! Even for an old vet’ like myself, I found it very enjoyable to play with. I would recommend all of you newer to middle class CQB and MP5 fans to go and purchase this gun from AirSplat (www.airsplat.com). One of the best things about them is that they ship fast and via UPS, which I’ve never have had trouble with. They also send you a tracking number as well. and the gun too.
