Looking for the ultimate airsoft pistol that combines a lightweight yet durable construction, insane rate of fire, and unlimited upgrade potential? Want to convert your sidearm into an HPA-powered machine pistol or DMR/sniper carbine?
That’s exactly why the AAP-01 Assassin from Taiwanese brand Action Army has earned its cult status among airsoft players. Its unique design inspired by the legendary Ruger MK4 with a modern tactical twist makes it stand out immediately. Internally, it features a robust gas blowback system built for Green Gas, but for those who want to push the limits, custom upgrades are available to suit any playstyle — whether you're building a backup sidearm, CQB primary, Speedsoft racer, or a sniper carbine with scope.
You’ll find all the necessary internal upgrades and external accessories in our e-shop, ready to drop straight into your cart.
The AAP-01 is built around a durable polymer frame with metal internals, offering an ideal balance between toughness and weight. It’s compatible with G-series magazines (TM, WE, VORSK, Raven, Novritsch) and supported by a vast ecosystem of upgrades from CTM TAC, Hadron Airsoft, CowCow and more.
Out of the box, it’s a versatile GBB pistol with adjustable hop-up, fiber optic sights, and semi/full-auto fire modes. Within minutes, you can turn it into a CQB beast, install an HPA conversion kit, or build a tactical long-range DMR setup. The outer barrel features a 14mm CCW thread for suppressors or tracer units, protected by a thread cap.
The fire selector is housed inside the blowback unit and requires you to pull the bolt back to switch modes. Hop-up is accessed by removing the slide, which is easily done even with gloves thanks to the release button on the back. The pistol also includes a metal trigger mechanism and a 129mm inner barrel with a 6.03 mm bore.
