Abstract
An assembly for testing the inner diameter of a rifled barrel of a firearm and a method of manufacturing the same. The assembly has a frame with side air discharge apertures and is intended to be connected to an air gauge. The assembly has a timing sleeve that is removably mounted to the frame such that the sleeve can be replaced when it becomes worn or when the assembly is intended to be used with a barrel having a different type of rifling. The assembly also comprises a wear ring such that the wear ring and timing sleeve absorb abrasive contact in the barrel to reduce abrasive contact by the barrel on the frame.
