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

For players who thrive in the chaos of CQB, the King Arms Mac-11 PDW KSC KWA M11 System 7 NS2 delivers speed, punch, and tactical finesse in a tight little package. This gas blowback airsoft gun takes the legendary M11 submachine gun blueprint and dials it up with modern PDW upgrades and enhanced internals—making it a nightmare for anyone on the wrong end of your barrel.

Built around a CNC-machined aluminium upper receiver, the M11 PDW doesn’t just look the part—it feels it too. Lightweight, yet rock-solid, with a rugged engraved handguard that offers enhanced grip during fast movements. Its extended front end increases the overall length to 525mm when the stock is deployed, giving you more control without sacrificing manoeuvrability. Add the side-mounted charging handle, and you’ve got a weapon that’s as intuitive as it is responsive under fire.

Internally, this compact GBB gets serious. At its core is the battle-proven KSC/KWA System 7 NS2 gas system—renowned for sharp recoil, efficient gas usage, and consistent shot-to-shot performance. Whether you’re bursting in full-auto or tapping in semi, the M11 PDW responds with crisp blowback and an authentic firing experience. With its upgraded 200mm precision inner barrel, expect BBs to fly at around 330 FPS on green gas with 0.2g ammo—perfect for indoor and close-range outdoor fields.

Need to go quiet? The 14mm CCW threaded barrel is ready for your suppressors or flash hiders. Prefer to keep it loud? Run it bare and let that muzzle pop. Either way, the retractable stock adjusts to your playstyle—tuck it in tight for room-clearing or extend it for more accurate follow-up shots. It’s a PDW that adapts to you, not the other way around.

Accuracy isn’t left to chance either. The adjustable hop-up lets you fine-tune trajectory on the fly, and with the 6.05mm tight bore barrel, you’ll notice a flatter shot path and tighter groupings, even during high-speed engagements. It’s fast, it’s fun, and it handles like a dream—perfect for aggressive flanking, sudden ambushes, or running as a secondary to a longer-range primary.

Rounding things out, you get a 48-round high-capacity metal magazine, and tactical rail space for optics or lasers. The M11 PDW may be compact, but it’s no slouch when it comes to firepower and modularity. Built tough and tuned for speed, this is one submachine gun that punches way above its size.
