Abstract
A method of operating a gas operated automatic or semi-automatic weapon that has a bolt that locks by a partial rotation of the bolt with respect to a bolt carrier, the bolt carrier in communication with a gas port on the barrel of the weapon, the method comprising utilizing the gas pressure from a cartridge received from a port in the barrel to unlock the bolt, and utilizing the expansion of a telescoping cartridge in the chamber to recycle the weapon after the bolt is unlocked. In embodiments the cartridge is a 5.56 mm cartridge. In embodiments, the propellant driving the projectile does not provide enough gas pressure to recycle the weapon and the telescoping cartridge supplements the needed power for recycling sufficient to accomplish the recycling.
