Chiappa's X-Caliber system turns a single break-action shotgun into a multi-caliber gun. The adapters drop into the chamber and let a 20 gauge barrel safely fire a range of smaller shotshell and rifle or pistol cartridges, each insert rifled or smoothbored as appropriate for the round it handles.

This four-piece set is built for 20 gauge hosts. It is a genuinely practical kit for a survival or trail gun, letting one shotgun feed on whatever ammunition is actually available, and a fun way to get more range time out of a gun you already own.
