King Arms PDW 9mm SBR Shorty

King Arms
  • Uses MP5 Magazine
  • Quick Change Spring
  • SBR Style AR Receiver

Built by the renowned King Arms this Airsoft replica is their first entry into the SBR style market, which features a 9mm lower receiver which takes Airsoft MP5 mags but retains all the features of an AR style rifle. Great for CQB environments and for those who want to make the transition between the MP5 and M4 platform.

Full description


The replica is an electrically powered Airsoft AEG which is powered by batteries and a motor which fire the 6mm BB pellets, and is magazine fed for easy reloading, as well as Safe, Semi, and Fully automatic firing modes. Constructed from a mixture of heavy duty Zinc Alloy and Nylon Fiber the replica features Alloy Internals, Stock Guide, Trigger, Working Parts, and Outer Barrel, with a Polymer Stock, Receiver, Pistol Grip, Flash Hider and Ironsight Set.

Thanks to the rifles short length it is perfect for CQB environments and is light enough to quickly move around corners for faster snap shooting in firefights. The weapon can be shouldered either left and right for taking corners, and can be easily reloaded in either shoulder thanks to the paddle style magazine release just like the traditional MP5. If the paddle style magazine release isn't for you the rifle also features a magazine release in the same position as the standard M4 as well.

If you're worried about the use of MP5 magazines you don't need to. The rifle does not use its own proprietary magazines like other similar style rifles on the market and has instead opted to use TM / Marui standard MP5 mags meaning most MP5 magazines on the market will be usable, allowing you to pick up a range of mid or high cap magazines depending on your play style.

The weapon also features a built-in hop up unit which is designed to add range and accuracy to the weapon by pushing a small patch of rubber into the path of the bb which adds spin during flight. The spinning causes the BB to displace air and create an air cushion to make its flight path more stable. The hop-up is adjustable allowing for a range of BBs to be used as well as for precision tuning of your shots to get the best range of the rifle possible.

The weapon features a four point 20mm RIS / RAS railed hand guard, as well as a railed receiver allowing for a wide range of aftermarket attachments to be connected to the replica. The handguard allows for grips and bipods to be added to the lower rail, as well as torches and lasers to the sides. The top rail of the handguard lines up with the top rail of the receiver to allow for larger sight and scope setups, such as advanced magnifiers and holographic configurations.

If you want to take this replica to the next level of customisation the sound enhancing flash hider can also be removed to reveal a 14mm Counter Clockwise male thread, allowing for the attachment of silencers, suppressors and even tracer units, with 14mm CCW being the most popular on the market with a wide selection of attachments available.

Internally the replica features a standard V2 gearbox, the most common type on the Airsoft market, meaning a wide range of upgrades and aftermarket replacement parts are available. The gearbox is rear wired with a mini-tamiya connector for attaching batteries, and features a quick change spring system allowing you to quickly adjust the FPS of the replica depending on your Airsoft game site's requirements.

This replica is perfect for those Airsoft skirmishers who need a small and compact CQB weapon and are conflicted between buying a Submachine Gun or a Rifle. Can't decide? Why not have both?
