Action Army AAP-01 Assassin GBB Pistol – Black
The Action Army AAP-01 Assassin is one of the most popular gas blowback airsoft pistols on the market for a reason: it’s lightweight, ridiculously fast, and built around a platform with near-endless upgrade options. Inspired by the iconic Ruger-style silhouette but feeding from G-series magazines, the AAP-01 is the perfect sidearm for CQB, speedsoft, and aggressive field play.
Looking for a pistol that can be a backup today and an HPA machine pistol or carbine build tomorrow? The AAP-01’s massive aftermarket makes it easy to evolve your setup from compact sidearm to SMG-style primary or even a DMR/sniper-support platform.

Built for Speed, Control & Real Gameplay
-
Semi + Full Auto – switch modes and unleash an insane rate of fire for room entries and close-range dominance.
-
Strong blowback feel – snappy cycling with a lightweight polymer frame that stays agile during long games.
-
Adjustable hop-up – dial in your BB flight for tighter groupings and more consistent range.
-
14mm CCW threaded outer barrel – mount suppressors or tracer units (thread cap included).
-
Aftermarket heaven – CNC internals, carbine kits, HPA adapters, optics mounts, and more.
Magazine Compatibility
The AAP-01 uses G-series (Glock-style) gas magazines, making it a smart choice if you already run TM/WE-style G mags. It’s an easy way to share mags across pistols and keep your loadout efficient on game day.
Care & Gas Recommendations
-
Set hop-up after purchase – if hop-up pressure is too low, BBs can roll out of the barrel.
-
Lubricate regularly with silicone oil (seals, moving parts, and trigger mechanism) to keep the GBB system reliable.
-
Use standard Green Gas only. Avoid high-pressure Red/Black gas and CO2 to prevent premature wear and seal damage.
