Abstract
A novel mechanism for moving a gun bolt toward and away from a firing chamber of a barrel assembly having movement relative to a receiver in a cartridge-firing weapon, having a camming channel formed in the receiver of the weapon, uses a rack member having an end coupled to the gun bolt and moving substantially linearly with the gun bolt toward and away from the chamber. A gear train has a housing affixed to the moving barrel assembly; an input member moves in the camming channel responsive to barrel assembly movement, to cause an output member to move the rack member and attached gun bolt toward and away from the chamber with substantially-linear displacement, velocity and acceleration greater than the associated displacement, velocity and acceleration of the moving barrel assembly with respect to the weapon receiver.
