Abstract
Leaf springs for use in a firearm magazine are described. The leaf springs comprising an inner edge, an outer edge, and a channel, and configured to facilitate movement of cartridges within a feed tower of the firearm magazine. The leaf springs can be in a flexed or unflexed position, wherein downward movement of the cartridges in the feed tower outwardly flex the leaf springs into the flexed position to facilitate downward translation of the cartridges by forcing the inner edge of the leaf springs away from the cartridges, and in the unflexed position, the inner edge of the leaf springs is parallel or substantially parallel to an edge of the cartridges in the feed tower.

A firearm magazine, comprising:
- a body;
- a feed tower;
- wherein the feed tower is configured to house one or more cartridges and comprises:
- a feed end opposite a base end,
- and
- one or more leaf springs positioned within the feed tower, wherein the one or more leaf springs are positioned closer to the base end than to the feed end, and wherein the one or more leaf springs are configured to bias the one or more cartridges through the feed tower towards the feed end or the base end of the feed tower;
- and
- the body is coupled directly to the base end of the feed tower and is configured to receive the one or more cartridges from the one or more leaf springs.
A leaf spring system comprising:
- one or more leaf springs comprising:
- an inner edge comprising a ramped surface,
- an outer edge, and
- a channel formed on the outer edge by vertical sections and shaped and sized to be secured over a rail in an interior of a feed tower;
- wherein one or more of the vertical sections and the outer edge are in contact with the interior surface of the feed tower;
- wherein a curved section is positioned between the inner edge and the outer edge and forms a C-shaped curve in the one or more leaf springs;
- and
- wherein the one or more leaf springs are positioned closer to a base end of the feed tower than to a feed end of the feed tower, wherein the base end is opposite the feed end, and wherein the base end is directly coupled to a body of a firearm magazine.
A firearm magazine, comprising:
- a feed tower;
- wherein the feed tower is configured to house one or more cartridges and comprises:
- a feed end opposite a base end,
- and
