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.

A gun capable of firing a variety of projectiles driven by a variety of propellants comprising: stock means barrel means quick connect means for readily connecting said barrel means to and disconnecting said barrel means from said stock means, without requiring the use of any hand tools, a plurality

A gun capable of firing a variety of projectiles driven by a variety of propellants comprising: stock means barrel means quick connect means for readily connecting said barrel means to and disconnecting said barrel means from said stock means, without requiring the use of any hand tools, a plurality of removable barrel insert means any one of which may be carried by said barrel means for supporting a predetermined propellant within a firing chamber defined by said barrel insert means, trigger means, and inertial firing pin means responsive to said trigger means, wherein said trigger means comprises a firing knob rigidly carried by a shaft and in which said stock means has a longitudinal groove formed therein in which said shaft may advance and in which said barrel means has a camming notch formed in the rearward end thereof in which said shaft may advance so that as the shaft advances into said camming notch, a camming action of said shaft against the surface of said camming notch ensures that the barrel means is fully seated against said stock means prior to full advancement of said inertial firing pin means.
