forward charging system 30 described above may be implemented on different types of firearms. Theforward charging system 30 described above may be implemented on firearms using a blowback system of operation, and/or firearm using a direct impingement system of operation, and/or firearm using piston system of operation. Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas crated by the ignition of the propellant charge. Direct impingement is a type of gas operation for a firearm that directs gas from a fired cartridge directly into the bolt carrier to cycle the action. Piston system uses gas pressure to mechanically move the bolt carrier to cycle the action. It is also to be understood that theforward charging system 30 described above may be implemented on M-16 and Armalite style rifles (ARs). - Referring to
FIGS. 16-20 , theforward charging system 30 is shown on anupper receiver assembly 300 using for example, a direct impingement system.
