Guntec Mid Length Gas Tube Features The Guntec Mid Length Gas Tube is manufactured from 304 stainless steel a material chosen for its resistance to corrosion carbon buildup and the extreme heat generated by cycling gas from the barrel to the bolt carrier group. At 11.75 inches long it is sized specifically for a mid length gas system so the gas port timing stays correct for reliable cycling. Stainless steel also holds up better than mild steel over repeated heating and cooling cycles which matters on a part that sees direct combustion gas on every shot. Builders replacing a damaged or bent gas tube get a durable long-lasting component rather than a short-lived stopgap. Installation is straightforward for anyone assembling or servicing an AR15 upper requiring only a roll pin punch and basic armorer tools to seat it into the gas block and gas key. Because it is a mid length tube it is intended for barrels built around a mid length gas system rather than carbine or rifle length setups so builders should confirm their gas system length before ordering. The Guntec Mid Length Gas Tube is a practical choice for a scratch build a parts kit completion or simply swapping out a worn or discolored tube during routine maintenance. For sale at GrabAGun it is an affordable durable way to keep a mid length AR15 upper running correctly.
