This video explains the mechanics of the long stroke gas piston system, a design popular in rifles and machine guns around 50 years ago. It details how the gas piston is attached to the bolt carrier, causing both to move rearward for the entire stroke of the cartridge. The description highlights its use in iconic firearms like the M1 Garand, Kalashnikov (AK), Browning Automatic Rifle (BAR), and ZB/Bren light machine guns. The system's benefits of improved extraction and feeding due to added momentum are discussed, as is its drawback of potentially increased perceived recoil.
