The gas tube is one of those small parts that carries a big job. It routes hot gas back from the gas block to the bolt carrier so your AR cycles every time you pull the trigger. This Tapco TAP22069 is the rifle-length version, cut for the longer 20-inch and up barrels running a full rifle-length gas system. If your barrel has a gas port sitting around 12 inches back from the chamber, this is the tube you want on it.
Tapco machines this tube to tight tolerances so it drops into a standard rifle-length gas block and locks into your gas key without any fuss. The anodized black finish helps it stand up to heat and resist corrosion over the long haul, which matters on a part that lives right in the gas stream and takes a beating shot after shot. It follows the mil-spec rifle-length pattern, so you're not fighting fitment on a proper AR-15 or M16 platform build.
Install is straightforward if you've done basic AR work. The tube slides into the gas block and gets pinned in place with a roll pin, then the back end feeds through the front sight base or gas block and into the upper. If you're not sure you need rifle length, measure from your barrel shoulder to the gas port. Roughly 12 inches to the port means rifle length is your answer. Grab the wrong size and the rifle either short-strokes or runs overgassed, so match it to your barrel before you order.
Tapco has a long track record supplying American-made parts for AR, AK, rimfire, and handgun platforms, and this tube fits right into that lineup. Whether you're building out a 20-inch precision upper, restoring a classic A2-style rifle, or swapping a worn tube on a long gun that's seen plenty of rounds, this one gets the gas moving the way it should. It's a no-drama replacement that keeps your action running smooth.
It's built for AR-15 barrels running a rifle-length gas system, which is typically 20 inches and longer. The gas port on those barrels sits around 12 inches back from the chamber. If you measure from the barrel shoulder to the gas port and land near that 12-inch mark, rifle length is what you need.
Measure the distance from your barrel's shoulder to the gas port. Roughly 4 inches is pistol, 7 inches is carbine, 9 inches is mid-length, and 12 inches is rifle length. Matching the tube to your port distance keeps the rifle from short-stroking or running overgassed.
This listing covers the gas tube itself. Roll pin inclusion can vary, so if you're doing a fresh build it's smart to have the correct gas tube roll pin on hand before you start. Most AR gas blocks use a standard-size pin for retention.
Yes. The anodized black coating adds corrosion resistance and helps the tube stand up to the heat it lives in right at the gas stream. On a part that takes abuse round after round, that finish helps it last through plenty of range time.
