摘要：A detachable large-bore regular barrel of a shotgun is replaced by a light-weight, thin-walled, carrier barrel having a bore in which a smaller-bore tube and an adapter are mounted. This enables the shotgun to fire a smaller-gauge shotgun shell without changing the weight and balance of the gun, since the combined weight of the carrier barrel, tube and adapter matches that of the regular barrel and those parts are designed to provide the same balance. The carrier barrel is provided with the same kind of shell ejector/extractor as the regular barrel. The adapter comprises a tubular member which defines a firing chamber for the smaller-gauge shotgun shell and is disposed in the breech end of the carrier barrel bore, being threadedly connected to the tube therein. The tubular member of the adapter prevents inadvertent insertion of a larger gauge shotgun shell into the carrier barrel and thus provides a safety feature. The adapter further comprises a slidable component which is slidably mounted on the breech end of the tubular member and engages a flange on the base end of the smaller gauge shotgun shell in the firing chamber of the tubular member. The slidable component is engaged with the ejector/extractor on the carrier barrel and is responsive to movement thereof from retracted to either eject or extract position to effect ejection or extraction of the smaller gauge shotgun shell.
