CT III choke tubes were used in the high rib Remington 1100 barrels that were sold through Shotgun Sports in the past. CT III choke tubes are approximately 2.5" long. We have available a limited number of these chokes available. They are only available in Light Modified, Improved Modified, and Full.
Unload firearm before changing choke tube. Never fire the gun without having the choke tube properly installed in the barrel. Make sure choke tube is tight. All chokes should be firmly tightened with an appropriate wrench. Read your gun’s manufacturers instruction book for safe operation.
