Abstract

A gun is provided which is capable of firing a variety of projectiles driven by a variety of propellants. The barrel may be readily disconnected from the stock of the gun. The breech is designed to receive a standard gauge shotgun shell. Inserts are also provided with the same general configuration of a standard gauge shotgun shell, and when placed into the breech, allow the gun to fire a variety of projectiles. Inserts are provided which allow the gun to fire both center fire and rim fire rounds through a bore in the insert. A rocket insert is also provided which contains a smooth bore and is capable of firing rockets. An inertial firing pin is provided, which operates in conjunction with a floating breech plate. The floating breech plate is used in the firing of compressed gas bottles. A dual action spring drive is provided which is used to provide the necessary force to drive the firing pin and which also absorbs a portion of the recoil.
