Cartridge Receiver

A cartridge receiver, also known as a cartridge chamber or cartridge housing, is a component of a firearm that holds and positions the cartridge (ammunition) in the chamber of the gun. It is typically located at the rear of the barrel and is responsible for accepting and aligning the cartridge with the firing mechanism.

The cartridge receiver is designed to securely hold the cartridge in place while allowing it to be easily loaded and ejected from the firearm. It also helps to ensure proper alignment of the cartridge with the barrel, which is crucial for accurate and reliable firing.

In semi-automatic firearms, the cartridge receiver often includes a mechanism that automatically loads a new cartridge into the chamber after each shot is fired. This allows for rapid and continuous firing without the need to manually load each cartridge.

Overall, the cartridge receiver plays a vital role in the functioning of a firearm by holding and positioning the cartridge for firing, ensuring proper alignment, and facilitating the loading and ejection of cartridges.
