A kit for modifying a bolt carrier group actuating apparatus of a firearm configured by its original manufacturer to have a gas-driven bolt carrier has a gas expansion assembly and an operating rod. The gas expansion assembly is configured for receiving combustion gases from an as-manufactured OEM gas block of a firearm and for facilitating expansion of the gases for generating a bolt carrier driving force. The operating rod is engagable between the gas expansion assembly and an operating rod engaging lug of a bolt carrier. The operating rod is configured to mechanically transmit the bolt carrier driving force to the operating rod engaging lug. |
