The Faxon Firearms Mid-Length Gas Tube (part no. ARGasTube-Mid) routes propellant gas from a mid-length gas port back to the bolt carrier on any AR-15 build running a mid-length gas system. Faxon Firearms, a Cincinnati, Ohio-based manufacturer known for precision-made AR components, builds this tube from stainless steel instead of the more common Parkerized carbon steel, giving it better resistance to heat cycling and corrosion over the life of the rifle. It’s a direct fit for any standard mid-length upper, whether you’re finishing a new build or replacing a bent or pitted factory tube.
