摘要： The invention relates to a firearm (100) comprising a barrel (101) comprising a gas opening, and a gas system (10), which gas system (10) comprises a gas block (11), a gas piston (12), a force transmitter assembly (13), an indexing part (21) and an indexing counterpart (22), gas openings (18). The gas block (11) is fixedly attached to the barrel and the gas piston (12) is positioned by the indexing part (21;22). In the gas system (10) gas is configured to pass through the gas opening of the barrel (101) via the gas openings (18) of the gas system into the gas block (11) and to set the gas piston (12) to movement. In the gas system (10) the gas piston (12) during its movement backwards is configured to close the gas opening of the barrel (101) for a defined time period and the gas piston (12) is not transmitting power/energy from combustion gas to the force transmitter assembly (13) unless the gas opening/-s (18) is/are closed.

摘要： An improved firearm includes in some embodiments a gas block of an indirect impingement system mounted on the barrel near the firing chamber to provide gas at a higher pressure for moving the piston that moves the bolt carrier. Some embodiments include low frictions rails on which the bolt carrier moves within the upper receiver. The higher gas pressure and the reduced friction from the rails reduce the required stroke of the piston, allowing a shorter firearm to be constructed. In some embodiments, mating elements, such as pins and corresponding openings, on the upper receiver and the lower receiver, align and provide additional structural strength to the upper and lower receiver.

摘要： An annular piston system for a firearm comprises a barrel, a gas block assembly, a piston, and a spring. The barrel has multiple sections lengthwise, one of the sections having at least one gas port hole to vent gas from the barrel. The gas block assembly is disposed annularly around the barrel and is adjustable to control an amount of gas flowing out of the barrel through the at least one gas port hole. The piston is disposed annularly around the barrel and can move longitudinally along the barrel in response to being pushed by the gas flowing out of the barrel. The spring is disposed annularly around the third section of the barrel and coupled to the piston. The spring limits a distance that the piston can move longitudinally along the barrel when the piston is pushed to move by the gas flowing out of the barrel.

摘要： A piston assembly (200) is provided for a gas-operated firearm of the type having a chamber and a barrel. The piston assembly includes a gas expansion housing (217) and a piston (232) mounted within the gas expansion housing. An annular recess (235) is formed in the outer wall of the piston to receive exhaust gases diverted from the barrel upon firing of the firearm. At least one longitudinally extending groove (237) extends from the annular recess to the head of the piston and forms a pathway for diverting the exhaust gases to the head. of the piston. During firing, pressurized gases are diverted into the annular recess and expand longitudinally from the annular recess to the piston head, whereupon the pressurized exhaust gas drives the gas piston rearwardly along the housing.

摘要： A recoil assembly for a rifle includes a barrel assembly, a bolt, bolt actuator, and a buffer assembly. The barrel assembly includes a barrel secured to a barrel extension. The barrel assembly is configured to be movably received through the fore end of the upper receiver and to move axially relative to the upper receiver when the rifle is fired. The barrel extension is coupled to a hydraulic buffer assembly located below the barrel extension and counteracts recoil forces acting on the barrel extension when the rifle is fired. A recoil spring is coupled to an op rod extending from a gas piston assembly on the barrel. The recoil spring counteracts recoil forces acting the bolt actuator when the rifle is fired.
