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. The invention include the telescoping cartridge providing a projectile with lethal energy and recycle capability for gas operated rifles. The subsonic cartridge may have at least 80 ft lbs of energy and operates subsonically.

Abstract translation: 一种操作气体自动或半自动武器的方法，其具有通过螺栓相对于螺栓承载件的部分旋转而锁定的螺栓，所述螺栓承载件与武器的枪管上的气体端口连通， 方法包括利用从筒中的端口接收的筒的气体压力来解锁螺栓，并且利用在腔室中的伸缩筒的膨胀来在螺栓解锁之后回收武器。 在实施例中，盒是5.56mm的盒。 在实施方案中，驱动抛射物的推进剂不能提供足够的气体压力以再循环武器，并且伸缩筒补充用于回收的所需功率，足以实现再循环。 本发明包括伸缩筒，为气体操纵的步枪提供具有致命能量和循环能力的射弹。 亚音速磁带可能具有至少80英尺磅的能量并且以子音方式进行操作。
