Polymer-based machine gun belt links and cartridge casings and manufacturing method
An example of a polymer-based machine gun link can include a first side having a finger to hold a cartridge and a second side, opposite the first side, having at least two fingers to hold a second cartridge. A stem can join the first side and the second side the two fingers are smaller than the finger and spaced along the stem so that the finger fits between the two fingers. All of the finger, the two fingers, and the stem are made from polymer.
1. A polymer-based machine gun link, comprising:
a top body made from polymer;
a bottom body, made from polymer, opposite the top body; and
a weakened seam between the top and bottom bodies and adhering the top and bottom bodies to each other;
wherein the top body further comprises:
a first side comprising a finger to hold a cartridge;
a second side, opposite the first side, comprising at least two fingers to hold a second cartridge; and
a stem joining the first side and the second side,
wherein the bottom body further comprises:
a first side comprising a finger to hold a cartridge; and
a second side, opposite the first side, comprising at least two fingers to hold a second cartridge,
wherein the at least two fingers are smaller than the finger and spaced along the stem so that the finger fits between the two fingers, and
wherein the finger, the at least two fingers, and the stem are made from polymer.
2. The polymer-based machine gun link of claim 1 , further comprising a section wherein the section is made from polymer and is adhered to at least one of the cartridge and the second cartridge.
