King Arms Mac-11 PDW KSC KWA M11 System 7 NS2 Airsoft Sub-machine Gun in Black

If fast-paced CQB skirmishes are your thing, then the King Arms Mac-11 PDW is the kind of gas blowback airsoft gun that just *feels* right in your hands. Compact, fierce, and surprisingly punchy, this little beast is based on the classic M11 but takes it up a notch with modern tactical flair. It’s loud, proud, and absolutely savage in tight spaces.

Let’s start with the build. This isn’t some flimsy plastic pea-shooter. The M11 PDW comes with a CNC-machined aluminium upper receiver that gives it that crisp, metallic clack when you cycle the action. There’s a unique engraved handguard that not only adds grip but looks sharp too. The extended front end lengthens the gun to a more controllable 525mm when the stock is out—meaning better handling without losing that signature SMG compactness.

Under the hood, this thing runs on the proven KSC/KWA System 7 NS2 gas system. If you know, you know. It’s reliable, snappy, and delivers a blowback that’ll put a grin on your face every time you squeeze the trigger. Whether you're laying down a controlled burst in semi or absolutely melting targets in full-auto, the M11 PDW handles it all smoothly with an estimated 330 FPS using 0.20g BBs. Not bad for such a small package.

The 200mm precision inner barrel is a big upgrade over the standard M11 setup. It boosts not just velocity but also gives better range and tighter groupings—something you’ll notice when you're clearing corners or picking off targets from cover. And yes, it’s got an adjustable hop-up system tucked inside so you can dial in your shot trajectory for maximum effect.

The tactical side of things is handled nicely too. A 14mm CCW threaded outer barrel opens the door for suppressors or flash hiders—great if you’re going for that sneaky special ops vibe. The retractable stock helps with shoulder support during aimed shots and makes transitions between compact and extended modes feel smooth and solid. It’s adjustable, and that’s key for staying mobile in CQB scenarios.

Reloading? Quick and satisfying. The high-capacity 48-round metal magazine clicks in with confidence and delivers reliable gas output, even during full-auto mag dumps. The side-mounted cocking handle is super intuitive and just feels cool to use—perfect when things get hectic and you need to cycle it in a flash.

It’s also got enough rail space to throw on a micro red dot or a laser if that’s your thing. The design keeps things simple and sleek while still giving you room to customise for your play style. Weighing in at about 1.6kg with the mag in, it's easy to run all day without fatigue, making it a great choice as either a primary for CQB or a secondary in outdoor games.

The King Arms Mac-11 PDW doesn’t just check the boxes—it scribbles all over the page with attitude. It’s built tough, shoots fast, and turns tight indoor fights into an absolute blast. For players who like to move fast and hit hard, this sub-machine gun is an absolute standout.
