摘要： Applicant has disclosed a method and apparatus to enhance feeding cartridges into the receiver of a bolt-action repeating rifle, from a detachable magazine. In the preferred embodiment, Applicant's invention strips the cartridges from the magazines and feeds the cartridges into the chamber by a spring-activated hinged flap, pinned in a mating recess in a breech bolt head, adjacent a well opening and the inserted magazine. The flap is biased by a spring, which tends to lower the flap away from the breech bolt head, when the breech bolt is in a retracted position. As the breech bolt is pushed forward, the flap engages a rim of the next cartridge to be fed from the magazine and pushes the cartridge out of the magazine, over a feed ramp of the magazine, towards the rifle's chamber. The flap raises, against spring pressure, as it contacts a feed ramp of the receiver, allowing the breech bolt to enter the locking area of the receiver.
