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 cocking the hammer. In so doing, a hook-shaped shoulder on its forward portion is disengaged from a corresponding recess in the receiver; and the whole bolt containing the hammer is free to move backward to its fullest extent. The firing-pin being linked to the hammer is also positively withdrawn from the face of the bolt. The piece is closed by reversing the motion of the bolt. It is held closed by a spring-catch (friction-pin) on its side.
It is locked by the descent of the hooked portion of the hammer into the recess of the receiver, when the piece may be fired by a back-action lock concealed in the bolt, the trigger alone being detached. The firing pin descends with the hammer along an inclined groove in the face of the bolt leading to the site of the fulminate in the center of the cartridge-head. Extraction is accomplished by a spring-hook recessed in the side of the bolt, and riding over the rim of the cartridge when the piece is closed. Ejection is caused by the cartridge-shell being quickly withdrawn on two longitudinal guides, one on each side of the receiver, and ejected by the head striking first a stop on one guide; and then almost simultaneously a stop to the rear of the first, on the other guide.
