The disclosure relates to firearms, especially recoil or gas operated firearms, having a receiver for cartridges, and having a magazine for containing a plurality of cartridges. The magazine can be disposed above and substantially parallel with respect to the barrel. The magazine includes a housing with a helically disposed member providing a helical passageway for the cartridges. The cartridges are supported on a cartridge carrier located in the housing, which can be rotated by a torque spring. The cartridges are unloaded from the magazine by a feed lip insert providing communication with the receiver of the firearm.
