A weapon is capable of firing cased telescoped (CT) ammunition rounds. The weapon includes a barrel, a chamber member that defines a chamber configured to hold a CT round for firing from the weapon, a non-rotating carrier body, and linkage. The linkage is constructed and arranged to move the chamber member (i) from a firing position in which the chamber member is aligned with the barrel for firing the CT round to an ejection/loading position in which the chamber member is not aligned with the barrel for ejecting a spent CT round and receiving a next CT round in response to the non-rotating carrier body moving away from the barrel, and (ii) from the ejection/loading position to the firing position in response to the non-rotating carrier body moving toward the barrel.

A firearm for firing cased telescoped (CT) ammunition cartridges that includes a split chamber configured to fully support a CT cartridge when it is fired, and that includes i) a dynamic rear chamber portion defining a pocket in a face of a bolt, and ii) a static front chamber portion that is integral to the barrel and separate from the bolt. A cartridge extraction mechanism engages the CT cartridge prior to the CT cartridge being fired, and holds the CT cartridge in the pocket in the bolt face as the bolt moves rearward to pull the CT cartridge out of the static front chamber portion and into an ejection position. An ejector is operable to eject the CT cartridge from the pocket in the face of the bolt when the CT cartridge reaches the ejection position.

A weapon for firing cased telescoped (CT) ammunition includes a barrel, a chamber member and a carrier assembly. The chamber member defines a chamber for a CT round for firing, and translates between a firing position aligned with the barrel and an ejection/loading position. The chamber member is spring-biased toward the firing position. Dual-feed structure provides for both a magazine mode as well as a belt feed mode of operation.

A magazine for storing cased telescoped (CT) cartridges and delivering the CT cartridges to a firearm configured to fire CT cartridges. The magazine includes a fixed lip and a moveable lip. The fixed lip and the moveable lip of the magazine are configured to prevent a CT cartridge located in a top-most position within the magazine from being pushed out a top of the magazine when the magazine is not fully inserted into a magazine well of the firearm configured to fire CT cartridges. The moveable lip may pivot laterally on a pivot point and move out of the way of the CT cartridge located in the top-most position within the magazine when the magazine is fully inserted and locked into the magazine well of the firearm configured to fire CT cartridges.

A weapon for firing cased telescoped (CT) ammunition includes a barrel. a chamber cavity aligned with the barrel, and a translating chamber member defining a chamber for holding a CT round for firing. The chamber member moves between a firing position in the chamber cavity and an ejection/loading position for ejecting a spent CT round and receiving a next CT round. A breech member closes a rear end of the chamber. A carrier performs a counter-recoil operation in which (1) the chamber member is moved from the ejection/loading position to the firing position with the next CT round therein, and (2) the breech is urged into a closed position against the next CT round in the chamber to remove headspace before the next CT round is fired from the weapon.

A cased telescoped cartridge that includes a cylindrical case surrounding a projectile, a front end through which the projectile exits when the cased telescoped cartridge is fired, and a thermal protective insert located at the front end. The thermal protective insert insulates the cased telescoped cartridge from heat emanating from a barrel of a firearm into a chamber of a firearm when the cartridge is loaded into the chamber of the firearm. The thermal protective insert is made up of at least one thermally insulating material, and is integrated into the front end of the cased telescoped cartridge.

A weapon for firing cased telescoped (CT) ammunition includes a barrel, a chamber member and a carrier assembly. The chamber member defines a chamber for a CT round for firing, and translates between a firing position aligned with the barrel and an ejection/loading position. The chamber member is spring-biased toward the firing position. The carrier assembly carries the firing pin and (1) performs a recoil in which a carrier and rammer move rearward from a battery position to bring the next CT round into a ramming position and to move the chamber member from the firing position to the ejection/loading position, and (2) performs a counter-recoil to return to the battery position and cause the rammer to push the next CT round into the chamber. The chamber member is released for biased return to the firing position for a next firing cycle.

Cased telescoped ammunition firearm with translating chamber

A magazine for storing cased telescoped (CT) cartridges. The magazine includes vertically extending side-wall ribs that project inwards into a loading channel. The side-wall ribs are positioned in alignment with a circumferential groove in each CT cartridge. The side-wall ribs prevent a backwards oriented CT cartridge from being pushed from the loading position through the loading channel into a body of the magazine. A moveable lip at the top of the magazine may move out of the way when the magazine is attached to a firearm, to allow the CT cartridge located in the loading position to be fed vertically out of the top of magazine. Each CT cartridge may include a thermal protective insert that provides thermal insulation from heat emanating from a barrel of a firearm when the CT cartridge is located in a chamber of the firearm.
