The AAP-01 Assassin is the first gas blowback Airsoft pistol from Action Army Company. Renowned in the Airsoft community for its upgrade parts, Action Army has expanded its product line into the gas blowback pistol market. Powered by green gas, the AAP-01 is capable of both semi-auto and full-auto firing modes by flipping the fire selector on the underside of the bolt carrier. All of the controls such as the magazine catch, safety, and slide catch are either ambidextrous or reversible, making the pistol friendly for right-handed or left-handed users. The barrel is 14mm CCW threaded underneath the orange thread protector, making it compatible with most Airsoft muzzle devices and accessories.
