    • A gas operating system (5) for a firearm renders the firearm capable of firing a wide range of shot loads by passively and/or automatically compensating for different shot loads. The firearm includes a plurality of ports (210, 212, 214, 230, 232, 234) formed in the firearm barrel, and corresponding ports (110, 112, 114, 130, 132, 134) formed in a gas cylinder (100) 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.
    • 用于枪支的气体操作系统(5)使得枪械能够被动地和/或自动地补偿不同的击球载荷来发射大范围的击球负荷。 枪支包括形成在枪支枪管中的多个端口(210,212,214,230,232,234)以及形成在气瓶(100)中的对应端口(110,112,114,130,132,134) 的气体操作系统。 端口在点火期间产生的用于循环枪支的气体。 当发射不同的药筒负载时,根据药筒的尺寸,端口的不同组合被选择性地至少部分地阻塞或以其他方式被盒壳体阻塞。
