King Arms PDW 9mm SBR series

At the IWA 2018 we could already see the prototype of the King Arms PDW 9mm SBR series. Now finally available!

The King Arms PDW 9mm SBR at the IWA 2018

We had already reported about this unusual weapon in our video on the King Arms booth at the IWA 2018 a few months ago. We remember it as an unusual mix of M4 and MP5. On the outside, it is an M4 with the PDW stock, which has recently become so widely used. Just with a very short barrel and interestingly shaped controls. Oh and the King Arms PDW 9mm SBR uses MP5 Magazine. So the next weapon of that kind of ARP9? Well, partially.

Handling the PDW 9mm SBR

The handling of the PDW is very pleasant due to the extraordinary controls such as the enlarged magazine release. I was able to see this for myself at the IWA. And that’s why there was also a small “highlight video” on my own channel.

Overview PDW 9mm SBR

Now the PDW is finally on the market (internationally at least, we in Germany still have to be patient). So finally there is some additional information.

This information refers only to the shorty version. Unfortunately, not all information (length/weight) is available for the other versions.

The receiver of the PDW 9mm SBR

The low weight of less than 2kg says a lot about this weapon. The body is therefore largely made of sturdy polymer. This makes the weapon also suitable for fast playing. The hand guard is also made of this material. Different versions with longer handguard, Picatinny or M-LOK system are available.

For example, the version shown in my video is the PDW 9mm SBR SD.

All PDW 9mm models use the popular PDW design for the stock. This stands out especially due to its simple operation. No button has to be pressed to pull out the stock. Simply pull hard on it and let it snap into the desired position.

All versions of the PDW 9mm SBR also have a continuous top rail. Optics, laser boxes (in DE only dummies of course) can be attached individually. According to our current information, all versions are delivered with simple flip-up visors.

The controls of the PDW 9mm SBR

The first thing we like about the PDW is the smooth Mag release on the right side of the receiver. This was also enlarged and thus enabled a quick magazine change.

The well-known mag release for the MP5/G3 series on the bottom side between trigger and magazine is still available. This allows MP5 users to quickly switch to this weapon with magazines and training.

The trigger has a straight bar, which theoretically favours very fast shooting cycles. Together with the Mosfet and the 11.1V LiPo battery recommended by King Arms this should be possible.

The safety and fire selector lever also has an interesting, more prominent design. This makes it easy to operate even with gloves on.

The Hop-Up System

Even such a compact PDW requires an adjustable hop-up system. This is of course located behind the fake-bolt. It can be realistically pulled backwards over the charging handle. A shortened dust cover protects it from dirt and is an addition to the appearance of the PDW.

All versions of the PDW 9mm SBR in the overview

Since the versions available so far differ only in the front part, the distinction is very simple.

PDW 9mm SBR Shorty

The shortest version, is also at the moment the only one with complete information. It is equipped with a Picatinny handguard and has the compactest dimensions of the PDW series.

We could already admire this version at the IWA. In the currently presented configuration it has an M-LOK Handguard, as well as an already installed silencer. This can probably also be removed at any time.

If you take off the silencer of the SD version, you have this pure M-LOK version. It looks a bit longer than the shorty version, but we can only see one version at the IWA.

A slightly longer barrel, together with a longer Picatinny system, results in the pure SBR version.
