Abstract: The firearm barrel cleaning system selectively cycles a stream of ultrasonic cleaning fluid through the barrel of a firearm, and further selectively ultrasonically induces cavitation within the cleaning fluid in the barrel for ultrasonic cleaning. The firearm barrel cleaning system includes a receiver assembly having a first end adapted for receiving the stream of cleaning fluid and a second end is adapted for insertion into the firearm receiver and sealing against a first end of the barrel to eject the stream of cleaning fluid into the barrel. A cap structure, having an outlet hose connector is clamped over the muzzle end of the barrel of the firearm. A pump selectively circulates the cleaning fluid through the receiver assembly, the barrel and out through the cap structure. An ultrasonic transducer is mounted on the receiver assembly for selectively inducing cavitation in the cleaning fluid.
