Abstract

A caliber-reducing adaptor kit for a revolver having an original revolver barrel, and a cylinder with a chamber having a powder-receiving compartment at one end. A substitute barrel, having a reduced caliber bore, is received in and is detachably mounted to the original revolver barrel. A cylinder insert is removably received in the cylinder chamber between the substitute barrel and the powder-receiving compartment, the insert having a caliber bore substantially the caliber of the substitute barrel. The cylinder insert includes a plunger having a head at one end engageable with an end portion of the substitute barrel, and having a shank portion, the bore being provided in the plunger. A sleeve is slidably mounted on the shank portion of the plunger and is engageable with the cylinder adjacent the powder-receiving compartment. The sleeve is retained captive on the plunger shank portion, and a resilient spring is located between the sleeve and plunger, providing relative movement of the sleeve and plunger under resilient loading. The substitute barrel includes an elongate tube extending internally of and spaced from the original revolver barrel, the tube having opposed threaded ends. A tubular fitting is threadedly connected to each threaded end, the fittings adjustably engaging and clamping the tube to opposite ends of the original revolver barrel.
