An assembly directing gas to an action of a firearm has a barrel with a bore and a forward sealing surface. A gas block has a bore, a port for directing gases from the block bore through the block port, a rearward sealing surface for sealingly mating with the forward sealing surface of the barrel, and a forward sealing surface. A component has a bore and is attached to a forward end of the barrel, the component bore being in fluid communication with the barrel bore. At least one port communicates the component bore with the block port, the component having a rearward sealing surface for sealingly mating with the forward sealing surface of the gas block. A portion of the component rearward of the rearward sealing surface is received within the bore of the gas block. The barrel and component cooperate to sealingly retain the gas block therebetween.
