In firearms operation, the term used to describe the mechanism where the action of the firearm is operated by the force generated from the shooting cartridge specifically refers to recoil-operated systems. In a recoil-operated firearm, the energy generated by the explosion of the cartridge forces the bolt backward. This movement not only ejects the spent cartridge case but also compresses the spring, allowing the mechanism to cycle and chamber a new round.

The recoil operation primarily relies on the momentum of the recoiling parts to perform their functions, which includes locking, extracting, and chambering. This method is commonly utilized in larger caliber firearms, where the recoil force is substantial enough to operate the action effectively.

In contrast, other operational types, such as gas-operated systems, utilize the gas produced from the burning powder to cycle the action, while blowback systems rely on the simple rearward motion of the entire slide or bolt without the use of a gas system. Direct impingement refers specifically to the manner in which gases are directed into the action to cycle the firearm, mainly seen in some modern rifles. Each mechanism has its applications and operational mechanics, but recoil operation distinctly utilizes the direct force of the cartridge's discharge for its action.
