Which of the following shotguns does not utilize a bolt carrier?

The Winchester 97 is a notable shotgun because it operates on a unique system known as a "slide action" or "pump" mechanism. This design allows the user to cycle the action by sliding the forend back and forth, which ejects the spent shell and chambers a new round. Unlike other shotguns that utilize a bolt carrier component in their semi-automatic or automatic action systems, the Winchester 97 relies solely on the mechanical motion of the slide to function. This distinctive feature sets it apart from shotguns like the Browning Auto-5, which employs a more complex mechanism involving a bolt carrier for its automatic operation, as well as other pump-action models like the Remington 870 and Mossberg 500 that operate on similar principles.

Thus, choosing the Winchester 97 is accurate as it does not incorporate a bolt carrier in its operation, highlighting its particular mechanical design and method of reloading.
