Abstract
Gas block assemblies for use with gas-actuated firearms include a flow-restrictor device that permits variation of the flow of propellant gas to the action of the firearm. The flow-restrictor device is switchable between a first position at which the device restricts the flow, and a second position at which the device does not present any restriction to the flow. In addition, the flow restrictor device can be configured to permit adjustments in the degree of flow restriction generated when the flow-restrictor device is in its first position.
