摘要： A gas operating system for a firearm renders the firearm capable of firing a wide range of shot loads by passively or automatically compensating for different shot loads. The firearm includes a plurality of ports formed in the firearm barrel, and corresponding ports formed in a gas block of the gas operating system. The ports tap gases generated during firing which are used to cycle the firearm. When firing different cartridge loads, differing combinations of the ports are selectively at least partially blocked or otherwise obstructed by the cartridge casing according to the size of the cartridge. Additionally, the gas operating system includes compensating gas pistons with internal relief valves that can bleed off excess gas to compensate for larger shot loads regardless of the size of the cartridge.

摘要： In an automatic shoulder arm designed as a gas operated weapon, especially an automatic rifle, the entire, fully operable weapon system, comprising the barrel, the bolt system, the gas operated action, the recoil spring arrangement, the cartridge feeding mechanism and a portion of the trigger mechanism, is slidably mounted in a receiver designed as a stock. During automatic fire, the weapon system is not returned to its initial position after every shot, but performs a recoil movement during a plurality of shots before it reaches a rear end position, which it maintains until the automatic fire is interrupted. The recoil movement can be utilized for controlling bursts of varying duration and cadence.

摘要： A gas operating system for a firearm renders the firearm capable of firing a wide range of shot loads by passively or automatically compensating for different shot loads. The firearm includes a plurality of ports formed in the firearm barrel, and corresponding ports formed in a gas cylinder of the gas operating system. The ports tap gases generated during firing which are used to cycle the firearm. When firing different cartridge loads, differing combinations of the ports are selectively at least partially blocked or otherwise obstructed by the cartridge casing according to the size of the cartridge.

摘要： There is disclosed a gas operated, fully automatic weapon system with a d feed mechanism having a long recoil, soft cycle operation. The automatic weapon system consists of six groups or sub-assemblies. These are the backplate (rear end cap/fire control assembly), the dust cover unit, the dual selective rotary feed unit, the operating group unit, the receiver unit, and the barrel unit. These sub-assemblies combine to provide a weapon characterized by lightness of weight, relatively slight recoil force, relatively slow gunfire rate, excellent manual control resulting in good burst fire accuracy in hitting targets, and safety during operation and disassembly.

摘要： A lightweight one man portable automatic gas-operated weapon system for intry use having symmetrical forces applied to recoiling parts by use of two parallel gas pressure actuated rods acting in unison. An integral sprocket feed system is actuated by the recoiling parts and avoids gross asymmetrical force movements about the weapon's center of gravity resulting from shifting ammunition weight. A dual tube receiver and dual gas system is featured in the weapon. Major weapon subassemblies comprising modules are operatively interrelated to facilitate replacement during field use of the weapon.

摘要： A gas cutoff system for use with a gas-operated firearm. The gas cutoff system includes a gas block affixed to the barrel and having a plurality of openings adjacent the barrel for receiving gas redirected from the barrel of the firearm upon firing. At least one gas cylinder is disposed within the gas block and includes a piston disposed within and moveable along the gas cylinder. A valve assembly is disposed within the gas cylinder adjacent to the at least one piston. The valve assembly includes a selectively closeable valve that can be actuated upon firing of the firearm when the volume/pressure of gas entering the gas block through the plurality of openings overcomes a biasing force of a spring so as to actuate movement of the valve within the gas cylinder. A portion of the valve is moved to a location blocking the openings through which the gas is entering the gas block to prevent excess gas from entering the gas operating system.
