A firearm barrel has a gas channel in fluid communication with a gas port. The gas port diverts a portion of the gas produced when firing a round of ammunition into the gas channel. The gas channel extends longitudinally and substantially parallel to a longitudinal axis of the barrel to a gas block.

A firearm barrel has a gas channel in fluid communication with a gas port. The gas port diverts a portion of the gas produced when firing a round of ammunition into the gas channel. The gas channel extends longitudinally and substantially parallel to a longitudinal axis of the barrel to a gas block. The gas channel provides fluid communication between a gas block and a gas port located in different longitudinal positions on the barrel.
