Faxon Firearms AR-15 AR-10 Gas Tube Features The Faxon Firearms AR-15 AR-10 Gas Tube is machined from stainless steel to hold its dimensions and resist pitting under the heat and pressure of a pistol length gas system. Because pistol length systems run hotter and cycle faster than mid or rifle length setups the tube s material matters more here than on a longer gas system and stainless steel is the proven choice for that environment. Its bright stainless finish also makes it easy to spot corrosion or carbon buildup during cleaning which helps builders catch wear before it becomes a reliability problem. The tube is built to Faxon s own manufacturing tolerances so it drops into a properly assembled upper without requiring additional fitting. This gas tube is compatible with both AR-15 and AR-10/LR-308 systems giving builders a single part that covers two platforms instead of stocking separate tubes for each. It ships complete with its own installation roll pin so there is no need to track down a separate pin before finishing the build. That makes it a straightforward option for anyone assembling a pistol length upper from scratch or replacing a damaged or worn gas tube on an existing rifle. Faxon Firearms backs the part with the same attention to tolerance and material quality found across its barrel and components lineup making this gas tube a dependable addition for any AR-15 or AR-10 pistol length build.
