ABSTRACT:
A choke tube assembly having a rear part and a front part selected from a plurality of front parts is releasably retained within a stepped cylindrical bore in the muzzle end of a shotgun barrel. The front and rear parts cooperate to define a forwardly converging forcing cone contiguous to a cylindrical choke bore which opens through the forward end of the front part. Each of the front parts define a choke bore of a different diameter. The shot pattern characteristics of the gun barrel may be altered by substituting one front part for another having a different choke characteristic.
