Chiappa X-Caliber Adapter for 12 Gauge Barrel – Multi-Caliber Chamber Insert System

The Chiappa X-Caliber Adapter transforms a 12 gauge smoothbore barrel into a multi-caliber platform by allowing the use of rifle and pistol cartridges through precision chamber inserts. This system provides versatility for hunters and shooters who want to fire centerfire rifle rounds from a break-action or single-shot 12 gauge firearm without changing barrels. The adapter uses interchangeable subcaliber inserts that chamber specific cartridges and direct them safely down the bore.

Installation requires removing any choke tube and inserting the appropriate caliber-specific sleeve into the chamber. The X-Caliber system is designed for use in break-action shotguns with removable chokes or open cylinder bores. Not all 12 gauge firearms are compatible—verify barrel specifications and bore condition before use. Each adapter is machined from heat-treated steel. Follow all manufacturer instructions regarding maximum pressures and compatible ammunition. Using incorrect adapters or ammunition can result in dangerous pressure conditions.
