The barrel (20) is readily removed from the receiver (15).

A receiver (15) and barrel assembly (10) is provided.

When the projectile is in the gun barrel, the outer surface of the annular ring contacts an inner surface (142) of a bore (140) of the gun barrel.

An obturator (210, 310, 410) is provided for a projectile (10) launched from a gun barrel (110).

The gun muffler includes a transition section fitted around the gun tube and engaging the gun tube for preventing the escape of residual combustion gases caused by the firing of a projectile by the gun.

A weapon system (8) having a gun barrel (30) and an in bore air regulation system (10).

Gun mantlet ring around the gun barrel is 305 mm thick.

This invention relates to a gun tube support assembly (10), which comprises four support sections (12) arranged annularly around a gun tube (13) and received in an opening in a cradle (15) of a gun.

The invention relates to a method for the all-round improvement of the military and operating characteristics of a rifled gun and to a rifled gun barrel device.

The barrel inclination is calculated from said values, and then a compensation for the barrel inclination is carried out by adjusting the alignment of the weapon barrel (11) in azimuth and/or elevation.

A weapon stabilization system (50) for an unbalanced gun tube (52) pivotally mounted on a tank turret.

The fall-back preventer ring engaging the barrel of the large caliber gun during a loading cycle and releasing from the barrel when the projectile is fired.

The sensor obtains environmental data that the projectile is exposed to when the projectile is inside a cannon tube.

Mark 8 was a simplified design consisting of a gun tube and jacket.

The present invention thus maintains the projectile safely within the barrel during loading and in the presence of other external forces.
