Abstract

Multi-modal gas blocks utilized in conjunction with gas piston-operated firearms are disclosed, as are firearms equipped with such gas blocks. In embodiments, the multi-modal gas block includes a gas block body, a valve element cavity, a gas inlet port through which the valve element cavity is fluidly coupled to a barrel bleed port of a firearm, a gas exhaust port fluidly coupled to the valve element cavity, and a gas return port fluidly coupling the valve element cavity to a gas piston cylinder contained in the firearm. A valve element housed within the valve element cavity is movable between: (i) a first position in which the valve element blocks gas flow from the gas inlet port to the gas exhaust port; and (ii) a second position in which the valve element divides gas flow received at the gas inlet port between the gas return and gas exhaust ports.
