ITHACA INFORMATION

Ithaca has used three different choke designs*.  The first design used in all Ithaca shotguns was the Tru-choke in both 12 and 20 gauge guns. Several years later they changed the choke to a Browning Invector/ Winchoke for the 12 gauge guns. To the best of my knowledge this design was not used in the 20 gauge guns.

Ithaca’s of current manufacture use a choke with the outside dimensions typical of Invector Plus chokes but is based on a .730 bore dia as cylinder.
