A device for cleaning an interior surface of a firearm includes a housing, an expandable scraping assembly, a control knob, and a drive rod. The housing extends longitudinally along a longitudinal axis. The housing has a forward end and a rear end longitudinally opposite the forward end. The expandable scraping assembly is located at the forward end of the housing. The control knob is located at the rear end of the housing. The drive rod is received within the housing and coupled to the scraping assembly and the control knob. Rotation of the control knob in a first direction expands the scraping assembly toward an open position. Rotation of the control knob in a second direction opposite the first direction contracts the scraping assembly toward a closed position.
