This breech-loading rifle has a fixed chamber closed by a movable breech-block, which slides in the line of the barrel by direct action. It is opened by first cocking the piece, then raising the handle of the breech-bolt to a vertical position, and then withdrawing the bolt until it is arrested by striking against the upper end of the recoil screw. In raising the handle, the beveled surface of the head of the firing pin bears against the tip of the recoil-screw, and thus positively retracts the firing pin. In withdrawing the bolt, it rides over the hammer and presses it back to the full-cock. The piece is closed by reversing the motion of the bolt. The tip of the recoil-screw prevents the firing-pin from moving forward until the breech is fully closed. It is locked by the base of the bolt-handle falling into a mortise in the side of the receiver. The piece is fired by a center-lock of the usual pattern. Extraction is accomplished by a spring-hook upon the side of the bolt. Ejection is caused by a sliding ejector playing into a groove in the bottom of the bolt, and, in the act of withdrawing the bolt, struck forcibly against the tip of the recoil-screw. This throws the shell around the hook of the extractor by which it is held, and expels it completely from the gun. It is impossible to move the bolt, in this arm, unless the hammer is at full-cock.
