AR-15 and AR-10 Gas Tubes for Reliable Cycling

The gas system routes propellant gas from the barrel back to the bolt carrier group to cycle your AR platform. White Label Armory stocks American-made gas tubes for AR-15 and AR-10 builds in four lengths: carbine, mid-length, rifle, and pistol. Matching the tube to your barrel's gas port location and handguard setup is a core part of any reliable build, so confirm your barrel's gas system designation before ordering.

These gas tubes suit both first-time builders and experienced gunsmiths, as well as firearms manufacturers sourcing components through white-label partnerships. Pair your tube with the right gas block and pick up the small parts you need from our pins and springs selection to finish the job.
