A choke, as it relates to firearms, is a narrowing of the end of the shotgun barrel.

This narrowing can be greater or smaller. Chokes that are smaller than the bore to a greater degree are called tight chokes.

Choke affects the shot pattern. Different chokes act differently with different loads and shot types.

Choke tubes are steel tubes with threads on the outside and one end having the same diameter as the bore and the other end being narrower to various degrees. These tubes are screwed into the end of the shotgun barrel to vary the choke. This provides shooters with more flexibility in using their guns for different types of shooting and different loads.
