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.

A gun cleaning apparatus includes a cleaning tool and a storage case. The cleaning tool has a cleaning section and a pull cord having a distal end for pulling the cleaning section through a gun barrel. The storage case is configured for enclosing the cleaning tool. The storage case includes a substantially hollow container defining a rim at opening thereof, and a removable lid positionable between a closed configuration and an open position. The removable lid includes a handle section for gripping by a user to assist with pulling the cleaning tool through the gun barrel in the open configuration and configured to engage the rim in the closed configuration, and a connection section extending from the handle section, the connection section defining an elongated slot and a cavity for securing the distal end of the pull cord therein.

A firearm maintenance tool can include a rigid body and a locking gate. The rigid body can include a spine, a foot, and a hooked head having a receiving cavity, wherein the rigid body is structured and configured to optionally house a plurality of pivotally connected tools. The locking gate can include a pivoting receiver at a first end of the locking gate that is pivotally connected to the rigid body, a removable connection piece at a second end of the locking gate, and a threaded shaft located at least partially within the pivoting receiver. The removable connection piece can have a threaded connection with threaded shaft and can at least partially insert into hooked head to lock the locking gate to the rigid body and create an enclosure for a strap.

A method for cleaning a firearm suppressor having firing residue deposits on inner surfaces thereof, includes: providing a hydraulic system including a cleaning chamber, a turbulence-inducing nozzle, and a non-petroleum-based cleaning solution; installing a used firearm suppressor onto the turbulence-inducing nozzle; placing the used firearm suppressor into the cleaning chamber; tempering the non-petroleum-based cleaning solution to a temperature between about 120° F. and about 180° F.; and flowing the non-petroleum-based cleaning solution through the turbulence-inducing nozzle and the used firearm suppressor at a predetermined pressure and flow rate during a predetermined period of time. An apparatus for cleaning a firearm suppressor having internal baffles and expansion chambers is also described.

A break open rifle and bolt action rifle having a barrel extension with a breech end for receiving a propellant charge, a muzzle end with an extended attachment structure for receiving a complementary attachment structure of a barrel, and a chamber disposed within and through the barrel extension having a first diameter at a first end and a narrowing portion adjacent a second end opposite the first end, the narrowing portion having a second diameter smaller than the first diameter, wherein the first diameter of the chamber is sized to receive the propellant charge therein, and the second diameter of the narrowing portion is sized to prevent the propellant charge from being further inserted past the narrowing portion, and to prevent a projectile from being inserted through the chamber from the barrel muzzle end. A bolt action configuration having dual diameter non-rotating bolt with an extractor and ejector mechanism for removing a propellant charge.

A break open rifle having a barrel assembly with a breech end for receiving a propellant charge—primer cap assembly, a muzzle end, and a carve out, slot, indentation, cavity, or recess, which receives a portion of the propellant charge—primer cap assembly extending beyond the rim of the propellant charge. A ramp section of the recess, adjacent to the first end of the barrel assembly, is included to facilitate receiving the extension of the primer cap in a rotational fashion as the break open rifle is configured from the OPEN position to the CLOSED position. The recess and accompanying ramp section are configured to receive that portion of the primer cap which extends from the flush surface of the propellant charge rim, independent whether the configuration includes a barrel extension or not. The ramp is configured to receive the extended portion of the primer cap as the loaded rifle is placed in the CLOSED position to prepare for firing.

The present disclosure describes devices and methods for disassembly and/or reassembly of firearms. The devices can include mechanisms such as a crank mechanism, guide rails, and stop plate to enable simplified disassembly and reassembly of a firearm.
