  • Choke tube wrench for any gauge shotgun
    Patent number: 4959917
    Abstract: A choke tube wrench is disclosed which greatly facilitates removal or installation of choke tubes by means of a cam-actuated expandable element which fits into the choke tube being changed. As the element expands it presses against the choke tube's interior, which keeps it from slipping. Projections on the wrench engage notches in the choke tube, helping to turn the tube.
