US12774863 - Jam-resistant drum magazine

Jam-resistant drum magazines and related methods are disclosed. In some implementations, a jam-resistant drum magazine includes a drum, which may have a base, a body, and a top. Some implementations of the drum include a tiered component having a platform extending from a support, and some implementations have a channeled component having a channel configured to receive a round of ammunition. Some implementations include a transition drum, which may have a cylinder with a chamber configured to receive the round of ammunition from the channel. In some implementations, the tiered component is configured to rotate with respect to the channeled component, thereby causing the round of ammunition to move along the platform toward the transition drum.

Claim 1

1 . A drum magazine comprising: a drum comprising: a tiered component having a spiraling platform forming a plurality of interconnected platform tiers; and a channeled component having a channel configured to receive a round of ammunition; and a transition drum comprising: a cylinder comprising a chamber configured to receive the round of ammunition from the channel, wherein the cylinder is configured to rotate in response to the round of the ammunition entering the chamber; wherein the channeled component is configured to rotate with respect to the tiered component, and wherein a rotation of the channeled component with respect to the tiered component causes the round of ammunition to move along the platform toward the transition drum. a drum comprising: a tiered component having a spiraling platform forming a plurality of interconnected platform tiers; and a channeled component having a channel configured to receive a round of ammunition; and a tiered component having a spiraling platform forming a plurality of interconnected platform tiers; and a channeled component having a channel configured to receive a round of ammunition; and a transition drum comprising: a cylinder comprising a chamber configured to receive the round of ammunition from the channel, wherein the cylinder is configured to rotate in response to the round of the ammunition entering the chamber; a cylinder comprising a chamber configured to receive the round of ammunition from the channel, wherein the cylinder is configured to rotate in response to the round of the ammunition entering the chamber; wherein the channeled component is configured to rotate with respect to the tiered component, and wherein a rotation of the channeled component with respect to the tiered component causes the round of ammunition to move along the platform toward the transition drum.
