Abstract : The patent relates to a gage for inspecting the lands of a rifled barrel bore for erosion which comprises a slider and a push rod axially disposed therein for displacing a feeler radially against one of the lands during movement of the slider along the bore. Radial deviations in the land are measured by calibrations on the push rod and the location of a deviation is indicated by graduations on the slider. Numbered radial lines on a supporting plug, respectively referenced to the lands, indicate the one thereof contacted by the feeler.
