The Tavor TS12 is a semi-automatic shotgun produced by IWI US, Inc.
The Tavor TS12 is a 12 gauge bullpup shotgun with the capability of being configured for left- or right-handed ejection and operation. It is gas-operated with a two-position gas regulator and a short stroke gas piston. It also features a cross bolt safety.
It feeds from one of three rotating magazine tubes that can hold either four 3 inch shells or five 2¾ inch shells. The TS12 also boasts the proprietary "Bullhead" bolt locking system, which automatically loads a round into the chamber once the next loaded magazine tube is rotated into position.
