    • A gas operating system for a firearm comprises a gas block defining a cylinder, a discharge gas vent coupled to the cylinder near a proximal end of the cylinder and a discharge gas inlet configured for pneumatic coupling with the barrel of a firearm near the proximal end of the cylinder. A piston in the cylinder is movable from a rest position distal of the discharge gas vent and the discharge gas inlet against the action of a return spring by discharge gas from a barrel of a firearm pneumatically coupled to the discharge gas inlet. A regulator is pneumatically coupled to the discharge gas vent to selectively control the flow of discharge gas from the discharge gas vent to modulate a volume of discharge gas advancing the piston. A diffuser may be provided pneumatically coupled to the regulator for diffusing any audible or visual report.
    • 用于枪支的气体操作系统包括限定气缸的气体块,连接到气缸附近的气缸的排出气体通气口,以及放置气体入口,其构造成用于与近端的火器近端的枪管气动联接 气瓶。 气缸中的活塞可以通过从与气体连接到排出气体入口的枪管的排出气体排出的气体相对于复位弹簧的作用,从放电气体排出口的远侧的静止位置和排出气体入口移动。 调节器气动地联接到放电气体排出口,以选择性地控制来自放电气体排出口的排放气体的流动,以调节推进活塞的排出气体的体积。 可以提供气动地连接到调节器的扩散器,用于扩散任何可听见或可视报告。
