Last round link feed system

A last linked assembly and clear spacer cartridge combination for use with a firearm using a firearm having a magazine well, and for use with a multi-cartridge ammunition magazine housing having an ammunition outlet for dispensing at least one live ammunition cartridge, and for use with a feed clip assembly having a double stack passageway portion tapering to a single stack exit location, said feed clip assembly configured to provide a passageway from said multi-cartridge ammunition magazine housing to said firearm proximate said magazine well, said last linked assembly and clear spacer cartridge combination comprising the following components:

• A) a leading linked dummy cartridge;
• B) a trailing linked dummy cartridge;
• C) a spreadable link for linking said leading and trailing linked dummy cartridges together while allowing them freedom to move between a more spaced apart relationship and a less spaced apart relationship, said leading and trailing linked dummy cartridges and said link comprising a last linked assembly;
• and
• D) a spacer cartridge configured to move along with leading and trailing linked dummy cartridges in a double stacked configuration as said spacer cartridge and said first and second dummy cartridges pass together through said double stack passageway portion of said feed clip assembly while said leading and trailing linked dummy cartridges are in one side of the double stack and said spacer cartridge is on the other side of the double stack, said spacer cartridge also configured to bias against said first and second dummy cartridges and spread them apart from their less spaced apart relationship position to their more spaced apart relationship as they approach said single stack exit location, to allow said leading linked dummy cartridge to push said at least one live ammunition cartridge out of said single stack exit location.

A combination of feed elements for use with a firearm using a firearm having a magazine well, and for use with a multi-cartridge ammunition magazine housing having an ammunition outlet for dispensing at least one live ammunition cartridge, and for use with a feed clip assembly having a double stack passageway portion and a tapering portion tapering to a single stack exit location, said feed clip assembly configured to provide a passageway from said multi-cartridge ammunition magazine housing to said firearm proximate said magazine well, said combination of feed elements comprising the following components:

• A) a leading linked dummy cartridge;
• B) a trailing linked dummy cartridge;
• C) a spreadable link for linking said leading and trailing linked dummy cartridges together while allowing them freedom to move between a more spaced apart relationship and a less spaced apart relationship, said leading and trailing linked dummy cartridges and said link comprising a last linked assembly;
• and
• D) a spacer cartridge configured to move along with leading and trailing linked dummy cartridges in a double stacked configuration as said spacer cartridge and said first and second dummy cartridges pass together through said double stack passageway portion of said feed clip assembly while said leading and trailing linked dummy cartridges are in one side of the double stack and said spacer cartridge is on the other side of the double stack, said spacer cartridge also configured to bias against said first and second dummy cartridges and spread them apart from their less spaced apart relationship position to their more spaced apart relationship as they pass through said tapering portion of said feed clip assembly and approach said single stack exit location, to allow said leading linked dummy cartridge to push said at least one live ammunition cartridge out of said single stack exit location.

A method of dispensing live ammunition from a multi-cartridge ammunition magazine housing having an ammunition outlet to a firearm having a magazine well, said method including the following steps

• A) providing the following:
• 1) a firearm with a magazine well;
• 2) a multi-cartridge ammunition magazine housing having an ammunition outlet;
• 3) a feed clip assembly having a double stack passageway portion as well as a tapering portion tapering to a single stack exit location, said feed clip assembly configured to fit in the well;
• 4) a leading linked dummy cartridge;
• 5) a trailing linked dummy cartridge;
• 6) a spreadable link for linking said leading and trailing linked dummy cartridges together while allowing them freedom to move between a more spaced apart relationship and a less spaced apart relationship, said leading and trailing linked dummy cartridges and said link comprising a last linked assembly;
• and
• 7) a spacer cartridge configured to move along with leading and trailing linked dummy cartridges in a double stacked configuration as said spacer cartridge and said first and second dummy cartridges pass together through said double stack passageway portion of said feed clip assembly while said leading and trailing linked dummy cartridges are in one side of the double stack and said spacer cartridge is on the other side of the double stack, said spacer cartridge also configured to bias against said first and second dummy cartridges and spread them apart from their less spaced apart relationship position to their more spaced apart relationship as they approach said single stack exit location, to allow said leading linked dummy cartridge to push said at least one live ammunition cartridge out of said single stack exit location;
• B) urging said last linked assembly and said spacer cartridge through said double stack passageway portion of said feed clip assembly while said leading and trailing linked dummy cartridges are in one side of the double stack and said spacer cartridge is on the other side of the double stack;
• and
• C) urging said last linked assembly and said spacer cartridge through said tapering portion of said feed clip assembly such that said spacer cartridge biases against said first and second dummy cartridges and spreads them apart from their less spaced apart relationship position to their more spaced apart relationship as they approach said single stack exit location, and such that said leading linked dummy cartridge pushes said at least one live ammunition cartridge out of said single stack exit location.
