A shotgun barrel with a constricted or tightened end that controls how pellets spread, used for hunting or sport shooting.
From 'choke' (to constrict) + 'bore' (the internal diameter of a gun barrel). Choke refers to how the barrel tightens to compress the shot pattern.
Choke boring is a precision engineering triumph—it uses the physics of fluid dynamics to control how 400+ pellets spread, and hunters have been modifying choke since the 1700s through pure experimentation.
