Abstract
A firearm magazine has a cartridge pushing means including a follower, an auxiliary follower, a relatively short main spring, and a relatively short auxiliary spring; as opposed to the conventional firearm magazine having one follower and one relatively long spring. If the invented firearm magazine and the conventional firearm magazine have the same size and both are fully loaded, all the springs--short ones and long one--are compressed to the same length, and it is obvious that the spring tension for the short spring is much less than the same for the long one, and accordingly the invented firearm magazine can stay fully loaded much longer than the conventional one, without losing restoring force of the springs.
Claims15
A firearm magazine comprising a tube having lateral walls, a cartridge pushing means including at least one main spring, at least one main follower being under the action of said main spring having an upper and a bottom ends, at least one auxiliary spring and at least one auxiliary follower being under the action of said auxiliary spring having an upper and a bottom ends, said auxiliary follower having an upper surface and a bottom surface, said upper surface of the auxiliary follower having at least one recess in which the bottom end of the main spring is located when the magazine is empty and in which almost the entire main spring is located when the magazine is fully loaded with cartridges, said bottom surface of the auxiliary follower having at least one recess in which the upper end of the auxiliary spring is located when the magazine is empty and in which almost the entire auxiliary spring is located when the magazine is fully loaded.
A firearm magazine comprising a tube having lateral walls, a cartridge pushing means including at least one main spring, at least one main follower being under the action of said main spring having an upper and a bottom ends, at least one auxiliary spring and at least one auxiliary follower being under the action of said auxiliary spring having an upper and a bottom ends, said auxiliary follower having an upper surface and a bottom surface, said upper surface of the auxiliary follower having at least one recess in which the bottom end of the main spring is located when the magazine is empty and in which a bigger part of the main spring is located when the magazine is fully loaded with cartridges, said bottom surface of the auxiliary follower having at least one recess in which the upper end of the auxiliary spring is located when the magazine is empty and in which a bigger part of the auxiliary spring is located when the magazine is fully loaded.
