The rifle barrel includes an extension having a ramp for loading the cartridges and having a key way for the shell extractor. The magazine of the rifle is mounted to the lower receiver so as to load the cartridges in a direction perpendicular to the rifle barrel. The magazine follower automatically locks the bolt after the last cartridge is fired. The bolt and bolt carrier are integrally machined, and fully enclose the cartridge to preclude out of battery firing.
