The Customisation King - Action Army AAP-01 Assassin GBB Pistol (Tan)

Ready to dominate the field with the most talked-about sidearm in airsoft? The Action Army AAP-01 "Assassin" in tactical Tan is a gas blowback pistol that rewrites the rulebook. Fusing Ruger-style ergonomics with a lightning-fast cyclic rate, this polymer powerhouse is the ultimate blank canvas for your perfect loadout.

Key Features & Performance

• Select-Fire System: A hidden selector switch under the bolt lets you switch instantly between crisp semi-auto and a blistering full-auto rate of fire.
• Fixed Outer Barrel: Unlike traditional GBB pistols, the stationary barrel ensures outstanding shot-to-shot consistency and laser-like accuracy.
• Unmatched Compatibility: Fully compatible with most TM-spec G-Series (G17/G18c) gas and CO2 magazines.
• Featherweight Bolt: The unique rear-cocking mechanism means less moving mass, resulting in superb gas efficiency and minimal recoil.
• Ambidextrous Controls: A reversible magazine catch and an ambidextrous bolt release make it perfect for both left and right-handed operators.
• Fibre-Optic Sights: Bright, easy-to-read sights allow for rapid target acquisition in dim environments.

The "Pro" Take

Why do so many veteran players run the AAP-01? It is simply the most versatile platform on the market. Out of the box, it is a lightweight, reliable sidearm that easily outperforms pistols twice its price. But its true magic lies in its aftermarket support. Whether you want to run it slick as a sniper's backup or build it out into a fully-fledged CQB carbine with drum mags and tracer units, the AAP-01 handles it all without breaking a sweat.

UK Spec & Site Performance

Firing consistently at around 300-320 FPS on standard Green Gas (using 0.20g BBs), the AAP-01 sits safely under the 350 FPS limit, making it perfectly legal for all UK indoor CQB centres and outdoor woodland sites. The semi-auto mode is incredibly snappy for tight urban engagements, whilst the full-auto feature is a brilliant "get out of jail free" card when you need to suppress the opposition (where site rules allow). Thanks to its efficient bolt design, it suffers from far less cool-down than standard metal-slide pistols, making it a highly reliable choice even during chilly British winter skirmishes.

Note: As a Realistic Imitation Firearm (RIF), a valid UKARA or suitable defence is required to purchase this pistol in its tactical Tan finish.

Friendly FAQ

What gas should I use for UK weather?
For most of the year, standard Green Gas works beautifully. If you are playing in the dead of winter, stepping up to Red Gas will help keep your FPS consistent and your cycle rate sharp.

Does it come with accessory rails?
The pistol features pre-drilled holes for top and bottom rails to mount torches and red dots, but the 20mm rails themselves are sold separately.

What BB weight is best?
Thanks to the excellent rotary hop-up, we recommend 0.25g BBs for indoor CQB, or 0.28g BBs to punch through the foliage at outdoor woodland sites.

Will it fit my Glock holster?
Standard hard-shell Glock holsters will not fit the AAP-01's unique profile. We highly recommend grabbing a dedicated AAP-01 retention holster or a universal fabric rig for the safest fit.
