Faxon Firearms Gas Tube Features The Faxon Firearms Gas Tube is manufactured from stainless steel specifically chosen for its ability to withstand the extreme heat and pressure cycling that occurs every time the rifle cycles. Carbine length gas systems run hotter and faster than mid-length or rifle length systems which makes tube durability especially important on shorter barreled AR builds. Faxon rates this tube to handle full-auto fire giving it a significant margin over typical factory tubes that are only tested under semi-auto conditions. That margin matters for anyone running a suppressor or an adjustable gas block both of which can increase pressure and heat in the gas system. Compatibility extends across both AR-15 and AR-10 / LR-308 platform systems so builders and armorers can stock a single carbine length tube for multiple rifle projects. The bright stainless finish resists corrosion better than many factory tubes which commonly show rust or pitting after extended exposure to carbon fouling and moisture. An installation roll pin ships with the tube so there is nothing additional to source before dropping it into a gas block. For builders replacing a bent or failing gas tube or upgrading before a suppressor install this Faxon tube is a durable straightforward solution.
