Abstract: A firearm servicing tool comprises a hinge piece, a fixed size wrench head, and first and second handle portions. The wrench head is attached and fixed in position relative to the hinge piece. Each of the first and second handle portions is pivotally connected to the hinge piece. The handle portions are movable relative to each other and relative to the wrench head in a manner such that the tool can be selectively reconfigured into at least first and second alternative configurations. The first and second handle portions engage each other and surround the wrench head when the tool is in the first configuration. The first and second handle portions engage each other with the wrench head extending outwardly therefrom when the tool is in the second configuration.
