This Guntec USA gas tube is sized for micro pistol-length gas systems on short-barreled AR-15 pistol builds. It carries gas from the gas block back to the bolt carrier key, and the rainbow PVD coating gives it a custom look visible through open handguards. Confirm your barrel's gas port length before ordering.
