Chiappa X-Caliber 12 Gauge 410 Bore / 45 LC Adapter Insert

The Chiappa X-Caliber gauge adapter insert drops into the chamber of any 12 Gauge break-action shotgun and lets you fire .410 Bore shotshells and .45 Long Colt pistol-caliber rounds from the same gun. This conversion kit is a single-piece steel insert finished in blued for corrosion resistance and easy cleaning.

Measuring 7" long, the X-Caliber functions as a rifled chamber insert that manually feeds a single round at a time. It is designed for any standard 12 Gauge break-action shotgun chamber, giving shooters a quick caliber-change option for adding .410 shotshells or .45 LC loads without buying a second firearm. The blued steel construction is rugged enough for regular range use while remaining easy to swap in and out of the host shotgun.
