Gas Tubes

The AR-15 is a gas-operated rifle platform, and the gas tube is one of the most critical pieces of the AR gas system.

On the AR, there is a small “gas port” (small hole) in the barrel that vents gas with every shot. This gas travels through the gas block and gas tube into the receiver, where it powers the bolt carrier group and auto-cycles the next round.

To learn more about AR-15 gas systems and how they function, check out our article: "Carbine, Mid, or Rifle? A Beginner’s Guide to AR15 Gas Systems"
