    • A sighting system for a fire arm, e.g. machine gun includes front and rear sight assemblies. The rear sight assembly has a pivotal L-shaped member having two different sized apertures. Pivotal and windage lateral movements of the L-shaped member are achieved via a threaded shaft and a knob held in place via a detent screw/plunger assembly. The L-shaped member is secured in place via the detent plunger spring assembly. The front sight assembly is configured for windage lateral movement and has a sight post that is raised and lowered and secured in place via detent plunger spring assemblies. Another embodiment includes a rear sight assembly which may be configured for windage lateral movement. Detent plunger spring assemblies secure an aperture member of the rear sight assembly and the front sight assembly during operation of the fire arm, and the front sight assembly is configured for elevational and windage lateral movements.
    • 火臂的瞄准系统,例如 机枪包括前视和后视组件。 后视镜组件具有枢转的L形构件,其具有两个不同尺寸的孔。 通过螺纹轴和通过定位螺钉/柱塞组件保持就位的旋钮来实现L形构件的枢轴和风向横向运动。 L形构件通过止动柱塞弹簧组件固定就位。 前视镜组件被构造成用于防风横向运动,并且具有升高和降低的瞄准杆,并通过定位柱塞弹簧组件固定在适当位置。 另一个实施例包括可以被配置为用于风向横向运动的后视组件。 止动柱塞弹簧组件在火臂的操作期间固定后瞄准器组件和前瞄准器组件的小孔构件,并且前瞄准器组件构造成用于垂直和阻止横向运动。
