Tapco Rifle Gas Tube Features The Tapco Rifle Gas Tube is engineered to meet strict manufacturing tolerances ensuring it delivers consistent gas flow to the bolt carrier group shot after shot. Reliable gas delivery is what keeps an AR platform rifle cycling properly so a well-made gas tube directly affects the reliability of the whole rifle. Built specifically to rifle-length gas system dimensions it is sized to work with rifle-length gas blocks and handguards without modification. The black anodized finish provides a layer of corrosion resistance against the heat and carbon exposure a gas tube sees with every round fired. Installing a quality replacement gas tube is a straightforward way to restore or upgrade the gas system on an AR-15 build whether replacing a worn factory part or finishing out a custom build. The anodized coating also helps the tube resist the buildup of carbon fouling that can accumulate over extended rifle use. Compatible with standard AR platform rifle-length gas systems it drops into builds using common rifle-length gas blocks.
