Abstract: A gas buffer plenum positioned at the end of the barrel of an automatic firearm. A barrel side end cap connects the system to the barrel. A plenum tube holds one or more chamber walls and retains gas pressure within the enclosure. A target side end cap creates the final pressure chamber enclosure and is attached to the plenum tube to lock the system together. This gas buffer plenum allows a bullet to leave the barrel of the firearm before the bolt of the firearm starts to open. As the gas buffer plenum is filled with the exploding gas behind the bullet, the gas chambers build and maintain pressure that is then forced back through a hole in the plenum. The gas is forced down a gas tube or into a piston system. Depending on the configuration of the firearm, either the gas force, or the piston, strikes the bolt and cycles the firearm. The system may also be used to retrofit a gas operated firearm that uses a traditional gas block design.
