AA AAP-01C Assassin Compact GBB Pistol – Black

Gas pistol AAP-01C Assassin Compact GBB by Action Army

Looking for the best compact airsoft pistol? One that combines a lightweight yet durable build, high performance with drill-like RoF, and endless upgrade possibilities? Want to convert it to HPA or transform it from a pistol to a full-on SMG?
That’s exactly why the AAP-01C Assassin from Taiwan’s Action Army has become a cult classic among airsoft players. Its unique and extremely compact design, inspired by the legendary Ruger MK4 in a tactical modern look, immediately stands out. The internal parts of the gas blowback system are tuned for medium-pressure Green Gas. But if you want to squeeze out more power, there’s a wide array of internal and external upgrades to match your playing style—whether it’s a sidearm, CQB primary, Speedsoft racegun, or a sniper-style DMR with a rifle scope. All necessary internal parts and external upgrades are available on our e-shop, so you can grab everything you need right away.

External and internal parts of the AAP-01C

The pistol features a unique construction with a durable polymer frame and metal internal parts, achieving the perfect balance between resilience and weight. It’s compatible with G-series magazines (TM, WE, VORSK, Raven, Novritsch), and has massive aftermarket support from CTM TAC, Hadron Airsoft, CowCow, and more—making it a true modular platform that never gets boring.
Out of the box, you get a compact GBB pistol with adjustable hop-up, fiber optic sights, and semi/full-auto firing modes. But in just minutes, you can turn it into a CQB monster, HPA build, or a tactical DMR rifle. The outer barrel has a built-in compensator without threading, so to mount a suppressor or tracer unit, you’ll need a dedicated adapter.
The fire selector is located inside the bolt unit (blowback housing) and requires cocking the bolt to switch. Adjusting hop-up requires removing the slide, which can be done easily even with gloves using the rear button. It also includes a metal trigger mechanism and an 84 mm inner barrel with a 6.03 mm bore.

  Add CNC upgrades, carbine kits, and accessories to fit your build.

Warning

• After purchase, you must adjust the hop-up pressure, otherwise BBs may fall out of the barrel.
• The pistol must be regularly lubricated with silicone oil (seals, moving parts and trigger mechanism).
• The pistol in stock configuration is intended only for medium-pressure gases such as Green Gas, e.g., ASG ULTRAIR Green Power Gas (135 PSI).
• Using high-pressure gases (Red Gas / Black Gas) or CO2 will damage the magazine seals and internals, and such damage is not covered by warranty due to excessive wear.
