KAK Industry Gas Tube Features The KAK Industry Gas Tube is manufactured in a carbine length configuration to fit the AR-15 platform routing gas from the barrel s gas port back to the bolt carrier group to cycle the action. A reliable gas tube is a critical link in any AR-15 build since any bend pit or leak can cause cycling issues or short stroking. KAK Industry builds its tubes to consistent dimensional tolerances so they install into carbine length gas blocks without binding or excess play. The Silver finish is applied for corrosion resistance helping the tube resist the heat and carbon fouling it is exposed to with every shot. KAK Industry was founded in 2011 to fill a gap in the market for quality American made components at prices builders could sustain over multiple projects. This gas tube reflects that philosophy offering a straightforward no frills replacement part without unnecessary cost. Note that the roll pin used to secure the tube to the gas block is not included so builders should have one on hand before installation. Whether replacing a bent or damaged tube or finishing out a fresh upper build this carbine length tube is a dependable affordable choice.
