A gun has parts that slide past one another during operation. A coating is formed on at least a surface of a first part that contacts a second part. At least an upper layer of the coating is porous and comprises a thermoset polymer and a filler. One or both parts may be part of a gas-operated reloading mechanism. The coating prevents jamming by excluding particles, yielding to particles that still manage to intrude, and by providing a reservoir for lubricant. The coating reduces clearances, improves accuracy, and reduces operating temperatures. The coating excludes particles from the lubricant, effectively allowing a large volume of lubricant to be used without the drawback of trapping dirt and other contaminants in the lubricant.

An apparatus and method of recoil mitigation for a gun mounted on a lightweight platform is disclosed.

A firearm maintenance system may be utilized to clean, lubricate and protect a firearm. Embodiments of the invention provide for creating a sealed environment between the breech end and muzzle end of the barrel of the firearm and introducing a maintenance fluid into the sealed environment. The maintenance fluid may be circulated within the barrel in a closed circulation configuration by a pump. The maintenance fluid may be heated. An ultrasonic generator may be utilized to induce cavitation in the maintenance fluid to improve cleaning efficiency. Fluid flow sighting devices may be utilized to visibly monitor operation. Electronic means to monitor and safeguard the firearm maintenance system may also be employed.

The Arms Power Cleaning Lubrication Coupler and Method enables gun barrel cleaning implements to be rotated by attachment to a chock of a motorized device such as to an electrical or battery powered drill. The coupler includes a body member having a tubular and linear configuration that defines an interior space. A first end of the body member is open and configured to receive and engage a drill chuck of the motorized device. A second end of the body member is open and includes an inner surface that is threaded and operable to receive and engage a cleaning implement such as a brush. In use, the motor may be engaged to rotate the wheel chuck which, in turn, rotates the body member, drill chuck and cleaning implement. The rotating cleaning implement provides enhances cleaning of an inside of a firearm barrel.
