Description
Action Army AAP01 Ruger MKII Gas Blowback Pistol Black
The Action Army AAP01, also known as the Assassin, is a gas blowback airsoft pistol designed by Action Army, the Taiwanese company best known for its precision sniper rifle parts and the popular AAC T10 bolt-action rifle. The AAP01 brings the same performance-led approach to pistols, with a distinctive, compact design and internals built around the widely supported 17-series pistol platform. This version is finished in black.
What sets the AAP01 apart is how open it is to customisation. It accepts popular 17-series gas magazines and a large and growing range of upgrade parts and accessories, so it can be built into anything from a lightweight sidearm to a stocked carbine-style setup. For players who like to tinker, it is one of the most rewarding pistols on the market.
Build and materials
The AAP01 combines aluminium alloy with fibre-reinforced polymer, alongside zinc alloy, plastic and steel parts where they are needed. The result is a light pistol, at around 655g, that is still rigid and well put together. Its fixed outer barrel and upper design give it a distinctive look that is quite different from a conventional slide-and-frame pistol.
Performance and internals
As a gas blowback pistol, the AAP01 cycles with each shot, giving felt recoil and a lively, responsive feel. The hop-up is adjustable and uses a VSR-style hop rubber, the same type used in many sniper rifle upgrades, which helps it put BBs where you aim. Hop-up should be set as described in the manual; with no hop applied, BBs can roll out of the barrel. The AAP01 range includes versions that offer semi and full-automatic fire.
Customisation
Action Army offers a folding stock for the AAP01, along with other accessories, letting you turn it into a compact, shoulder-fired setup for CQB. A wide range of aftermarket parts is also available, from barrels and hop-up rubbers to cosmetic upgrades.

Care and maintenance
Lubricate magazine seals and fill valves with a drop of silicone oil every few fills, and do not overfill. Store magazines with a small amount of gas inside. Keep moving parts lightly lubricated with silicone oil and wipe the pistol down after use. Clean the barrel occasionally with a rod and dry patch, and use good quality seamless BBs, which make a noticeable difference with a precise hop-up like this one.
Who is it for?
The AAP01 suits players who want a light, responsive gas pistol with plenty of scope for upgrades, and anyone who already owns 17-series magazines and wants to make use of them.
