CHIAPPA X-Caliber 12GA to 20GA Shotgun Adapter

The CHIAPPA X-Caliber 12GA to 20GA shotgun adapter lets you fire 20-gauge ammunition safely through a 12-gauge shotgun. If you've got a 12-gauge in your safe and want to shoot smaller, lighter-recoiling 20-gauge rounds without buying another gun, this adapter makes it possible. It's a straightforward piece of kit for hunters and shooters who value flexibility and want to reduce recoil or ammunition costs on the same platform.

This adapter sits inside the barrel of your 12-gauge shotgun and creates a firing chamber for 20-gauge shells. It's the kind of accessory that makes sense if you're alternating between gauges depending on game, distance, or shooting conditions—or if you're introducing someone new to shotguns who'd benefit from less recoil. Before using any adapter, verify it's compatible with your specific shotgun model and always follow your firearm's manual and all local firearms laws.

CHIAPPA makes compact, practical firearm accessories for hunters and sport shooters. The X-Caliber adapter is one of their solutions for folks who want to get more flexibility out of existing hardware.
