ABSTRACT:
A weapon which can be simply and quickly converted for use as either a firearm or as an airgun is disclosed. Removable chamber devices and bolt faces are adapted for different types of projectiles, such as pellets or cartridges. A number of bolt faces and chamber devices are provided for each type of projectile used. A conventional pressurized gas assembly provides the pressurized gas needed to propel the pellet. A hammer and trigger assembly mounted below the bolt housing releases a hammer to fire the weapon. When in the firearm mode, the hammer strikes a firing pin extending from the cartridge bolt face. When used in the airgun mode, the hammer strikes a gas pin which allows pressurized gas to enter into the pellet chamber device forcing the pellet out of the barrel. After each shot, the bolt assembly is drawn rearward to recock the weapon by either a firing pin in the firearm mode or by a hammer puller in the airgun mode, each extending into the path of the hammer from the corresponding bolt face.
