摘要： An automatic projectile firing weapon and a related method for absorbing the recoil force of an automatic projectile firing weapon are disclosed. The weapon includes a barrel assembly that is slidably mounted in a receiver, biased by an operating spring, and engageable with a main sear. A gas operated bolt assembly is slidably mounted within the barrel assembly and is driven by a bolt spring. A trigger is provided to release the main sear and allow the operating spring to move the barrel assembly forwardly in the receiver. There is further provided a buffer connected between the receiver and the barrel assembly to dampen the velocity of the barrel assembly to ensure the barrel assembly is moving at a predetermined maximum velocity when a round is fired at a predetermined firing position. The recoil energy from the fired round is absorbed mainly by the forward motion of the barrel assembly and in part by the operating spring and buffer. In this manner, the peak recoil load to the receiver is minimized and the weapon operates at its actual firing rate from the first shot.

摘要翻译： 公开了一种自动射弹射击武器和一种吸收自动射弹射击武器反冲力的相关方法。 武器包括可滑动地安装在接收器中的枪管组件，由操作弹簧偏压并可与主焊盘接合。 气动螺栓组件可滑动地安装在筒组件内并由螺栓弹簧驱动。 提供触发器以释放主触头并允许操作弹簧在接收器中向前移动枪管组件。 还有一个连接在接收器和筒组件之间的缓冲器，用于抑制枪管组件的速度，以确保当一个圆在预定的击发位置发射时，枪管组件以预定的最大速度移动。 来自发射圆的反冲能量主要由筒组件的向前运动部分地被操作弹簧和缓冲器吸收。 以这种方式，对接收器的峰值后坐负载最小化，并且武器以其第一射击的实际发射速率运行。
