ABSTRACT:
A gauge adapter for a break-action shotgun, including a bullet barrel fixed in a plug having the dimensions of the shot cartridge. The adapter includes a resilient pressure device, disposed for pressing the plug solidly against the wall of the transition cone in the shot bore when the fire-arm is closed. The forward part of the plug has a rounded breast for bearing against the transition cone, the radius of the breast corresponding to the cylindrical radius of the plug. The breast thus acts in the transition cone as the ball in a ball joint. The resilient pressure device can be an elastomeric pressure pad disposed in a practically cylindrical cavity in the rear face of the plug. The pressure pad is outwardly covered by a plate extending up to half the bullet barrel and has a cut-out for the bullet cartridge. In the area of the cartridge rim, the plate has a depression for engaging under the rim of the cartridge. When the fire-arm is opened, the plate acts as a shell extractor so tht the shell can be gripped and taken out with the aid of a finger nail.
