Abrégé
An adjustable gas block for a gas operated firearm is provided that offers the user a means by which the volume of gas being directed to the host rifle's operating system can be adjusted. The adjustable gas block provides two positions of adjustment, with the position of use being selected based on whether or not a back pressure increasing device, such as a noise suppressor or a silencer, is mounted on the firearm. A first position provides the optimal volume of gas into the gas operating system for it to operate properly based on its factory configuration and in the absence of a back pressure increasing device. A second position is available for use when the back pressure is increased due to the presence of a back pressure increasing device. The second position exposes a port through which a portion of the volume of gas from the barrel is vented into a secondary chamber prior to being released into the atmosphere. By venting a portion of the gas into a secondary chamber, the amount of gas received by the operating system is reduced to a volume that is substantially equal to the volume of gas that would be received by the operating system in the absence of a back pressure increasing device. No tools are required to select either of the positions provided by the gas block.
