  • Publication number: 20130047484
    Abstract: A firearm cleaning device with a cartridge-shaped handle and a slotted cleaning connector for securing a disposable cleaning patch, both of which are removably engaged with an extendable ramrod. The cleaning device can be securely stored in the barrel of firearms of different action types and the cartridge-shaped handle fits in the chamber to allow the innocuous release of the hammer when a live cartridge is not present. Thus, the firearm cleaning device is conveniently stored while protecting the firearm and acting as a safety device.

  • Publication number: 20120291803
    Abstract: A novel firearm pull-through cleaning tool with an integrated foldable handle. The handle is pivotable at a first tool end between a closed position wherein a portion of the handle occupies a longitudinal well in the tool body and an open position wherein the handle is substantially transverse to the longitudinal axis of body. When in closed position the diameter of the tool is less than the bore diameter of a weapon to be cleaned. In use, the handle is pivoted in a first direction to place the tool in the closed position; the tool is inserted into the firearm bore; a cleaning tool is attached to the attachment portion; the tool is passed through the bore; the handle is pivoted in a second direction to place said tool in the open position; and the handle is pulled to cause the cleaning tool to be passed through the bore.
