Abstract: An eccentric rail mounting system is disclosed. In various embodiments, this system comprises an eccentric rail nut for off-center mounting of a rail on a firearm. The eccentric rail nut has an exterior surface that defines a central axis of the nut and a main bore that defines a central axis of the main bore that is displaced from the central axis of the nut. Components and methods are disclosed in a variety of embodiments.

Abstract: An apparatus comprising a tool body having parallel columns extending from a common base. The base includes a lip extending outward from the columns defining an anvil for receiving a delta ring. A cutter has a body slidably disposed between the columns. A blade extends outward from the cutter body in opposition to the anvil and is aligned by transverse guide pins extending through guide slots in the columns. In operation, a section of the delta ring is positioned between the blade and the anvil. The blade is driven toward the anvil by any of various mechanical, pneumatic, and/or hydraulic mechanisms connected to the stanchion and blade, the simplest of which is a bolt extending through the cutter body and received in a threaded bore in the base. Preferably, the anvil includes a slot for receiving the blade at the extreme of its travel as the ring is severed.

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.
