This list is believed to be correct but is not guaranteed to be so.  Manufacturers may change designs at any time without notification. In some cases there may be several different choke designs that have been used in the same model. If you are not SURE which choke fits your shotgun, please call for technical support. Never attempt to force a choke that does not screw in easily. Trulock Tool and or Whigham Enterprises Inc. assumes no liability for use of this chart.

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.
