US12332012 - Gas-operated firearm

A gas-operated firearm has a frame, a barrel defining a bore having a forward muzzle end and an opposed rear end defining a chamber, a bolt assembly received in the frame and operable to reciprocate between a battery position and a recoil position, the barrel defining a gas aperture communicating with the bore, a gas operating system connected to the frame, having a gas inlet, and operably connected to the bolt assembly to move the bolt assembly from the battery position toward the recoil position, and the gas inlet being forward of the gas aperture. There may be a gas conduit extending forward from the gas aperture to the gas inlet. The gas aperture may be proximate the rear end of the barrel. Unlike conventional gas-operated firearms, the barrel is free of contact with any other elements except proximate the rear end of the barrel.

The patent describes a gas-operated firearm featuring a unique design where the barrel is only in contact with other elements at its rear end, allowing for improved operation. It includes a gas operating system with a gas inlet positioned forward of the gas aperture, enhancing the efficiency of the bolt assembly’s movement between battery and recoil positions.

Claim 1

A gas-operated firearm comprising: a frame; a barrel defining a bore having a forward muzzle end and an opposed rear end defining a chamber; a bolt assembly received in the frame and operable to reciprocate between a battery position and a recoil position; the barrel defining a gas aperture communicating with the bore; a gas operating system connected to the frame, having a gas inlet, and operably connected to the bolt assembly to move the bolt assembly from the battery position toward the recoil position; the gas inlet being forward of the gas aperture; including a gas conduit extending forward from the aperture to the gas inlet, the gas conduit serially intervening between the gas aperture and the gas inlet. a frame; a barrel defining a bore having a forward muzzle end and an opposed rear end defining a chamber; a bolt assembly received in the frame and operable to reciprocate between a battery position and a recoil position; the barrel defining a gas aperture communicating with the bore; a gas operating system connected to the frame, having a gas inlet, and operably connected to the bolt assembly to move the bolt assembly from the battery position toward the recoil position; the gas inlet being forward of the gas aperture; including a gas conduit extending forward from the aperture to the gas inlet, the gas conduit serially intervening between the gas aperture and the gas inlet.
