Tapco Gas Tube Features The Tapco Mid-Length Gas Tube is manufactured to precise tolerances so that it delivers consistent gas pressure back to the bolt carrier group on every cycle. This consistency is critical for reliable function since a gas tube that is out of spec can cause short stroking over gassing or premature wear on other components. Built specifically for mid-length gas systems this tube is sized correctly for rifles with the longer gas system length found on many modern AR-15 builds. A durable anodized black finish protects the tube from the intense heat and carbon fouling it is exposed to with every round fired. Because gas tubes are a wear item subject to repeated thermal cycling having a quality replacement on hand helps keep a rifle running reliably through high round counts. The Tapco gas tube installs the same way as factory tubes dropping into the barrel s gas port and locking into the front sight base or gas block without modification. Its anodized finish also resists corrosion which matters for a part that sits directly in the path of hot combustion gases shot after shot. The Tapco Mid-Length Gas Tube is a straightforward affordable way to keep an AR-15 platform rifle cycling reliably for years to come.
