ASG STI Duty One Blowback

Pretty accurate pneumatic replica of the original Duty One. Among the noticeable differences can only be the shape of the trigger. The combat mechanism of a single action, in order to make the first shot, the shooter must either pull the bolt or cock the hammer. After the first shot, the pistol will cock automatically, under the action of compressed gas from a replaceable cartridge. The pistol has a smooth 4.5 mm barrel and is designed to fire a 4.5 mm metal ball.
