The Well R-4 MP7 is an extremely good airsoft replica of the real Heckler & Koch MP7. The following is a photo of the real H&K MP7A1 on display at the Germany's IdZ program. You can use this photo to compare to the Well R-4 1:1 MP7 replica photos in this article. Click on the photo below to see a full-size image.

The Well R-4 comes in a well designed package. The box looks great (see photo below).
Inside the box, you will see everything inserted tightly into the styrofoam (see photo below). Content includes the MP7 airsoft gun, a proprietary battery, battery charger, and a bag of BB's, and the instruction manual.
The H&K MP7 is a very small full-automatic sub-machine gun. The Well R-4 electronic airsoft version is no exception. But with the shoulder stock and the foregrip extended (see photo below), it becomes a sturdy rifle that matches a bullpup. The foregrip is not removeable, just like the real MP7. All of the other airsoft MP7 replicas on the market have a removeable foregrip attached to bottorails.
Notice that my Well R-4 is missing the side Picatinny weaver rail (see photo below). It seems that the manufacturing plant forgotten to install the two rails on this airsoft gun, because the gun has came well packaged in original shrink wrap (not a return). I have bought my own side rails to install on this gun.
The battery bay is just behind the front muzzle (see photo below). The Well R-4 has a small proprietary battery, because the gun is so small, there is hardly any space for the battery.
Noticed that the mode switch is ambidextrous. The photo below shows the safety being at the top position, semi-auto is in the middle position, and the full-auto is in the bottom position.
The charging handle opens the shell ejection port just above the mode switch, on the right side of the gun. Once the shell ejection port is opened, you can see and adjust the hop-up unit. The shell ejection port is quite narrow. So I have difficulty getting my finger into it to adjust the hop-up. Instead, I have to use a hex wrench to make my adjustments.
In addition to the mode switch, the trigger has another safety switch (see photo below). When you pull the trigger, you will automatically depress the safety switch. Without depressing this switch you cannot pull the trigger. It is not clear to me why this extra switch is necessary.
The magazine release is right where the trigger guard meet the handgrip. Use your thumb to push down on it and the magazine slides right out. The magazine release is also on both side of the gun.
Although AirSplat claims that this gun comes with a 50-round magazine, it actually only comes with a 20-round real-capacity magazine (see photo below) to simulate the real firearm. A 50-round mid-cap version and an 150-round high-cap version are also available.
Much like other mid-capacity magazines, the included MP7 magazine has a BB release switch (see photo below).
AirSplat claims that the Well R-4 MP7 shoots at 260 FPS with 0.2g BB. In our test, we get an average of 215 FPS with 0.2g BB. There is definitely room for improvement. Maybe AirSplat has a perfect sample with no air leaks and the one we got has plenty of air leaks.
