Abstract: An adapter is mounted on a gun barrel near its free end. The adapter conts spaced-apart fulcrums with an actuator between the fulcrums for bending or flexing the barrel with respect to the fulcrums. This bends the barrel, causing the muzzle of the barrel to move and thus re-air the barrel independently of a mount which carries the barrel. The adapter can be used in a rapid fire weapon. The flexing condition of the barrel at each round of a burst of fire is recorded and then used to supply forces to the barrel during a subsequent burst of fire. The applied forces compensate for the uncontrolled flexing of the barrel to increase accuracy.

Abstract: A method and apparatus is shown for programming near perfect accuracy for ch shot in a rapid burst machine gun sequence which heretofore was not known to be attainable. Because of vibrations from many sources in the barrel, which are predictable and repeatable, it is impossible for each shot to land directly, except for the first one before vibrations really begin. Each succeeding shot (a different path) has its own signature. In this invention, the barrel is precision bent (flexed) at each instance of the sequence, to compensate for the known vibrations, as each shot travels the barrel, to get a straight shot every time.An adapter is mounted on a gun barrel near its free end.
