The Autococker, also known as the AutoCocker, or 'Cocker, is a closed-bolt semiautomatic paintball marker manufactured by Worr Game Products (WGP). It is known throughout the paintball community for its popularity and customizability, as well as its complexity. It is commonly believed that the closed-bolt design of the marker makes it inherently more accurate than its open-bolt counterparts, though this is disputed (see Accuracy, below).
