Description
A gas tube is one of those small AR parts that does a big job, and this is where it pays to buy quality. The Wilson Combat Pistol Length Gas Tube is a genuine AR-15/M16 component made to military specifications by a government contractor, so you get the same tolerances and materials the platform was designed around. It measures 6.625 inches overall, which is the pistol-length spec, and it's built from mil-spec stainless for the corrosion resistance and heat tolerance these tubes need to handle repeated firing cycles.
Where the Wilson Combat Pistol Length Gas Tube Fits
Pistol-length is the shortest gas system on the AR platform, and it's what you'll typically run on short barrels in the 7 to 10 inch range. The gas port location on your barrel dictates which tube length you need, so match this one to a barrel cut for pistol-length gas. Get that pairing right and the tube routes gas back to the carrier group at the correct timing for reliable cycling. Run the wrong length and your rifle won't function properly, so it's worth double-checking your barrel spec before ordering.
Building or Repairing With the Wilson Combat Gas Tube
This tube works equally well as a straight replacement for a worn or damaged part or as a component in a scratch build. Stainless holds up to the constant heat and gas exposure better than cheaper materials, which is exactly why folks reach for a name like Wilson Combat when reliability matters. One thing to keep in mind: the roll pin that secures the tube to the gas block is not included, so if you don't already have one on hand, grab a gas tube roll pin to go with it.
Wilson Combat has been building custom pistols, rifles, and parts since 1977, and their reputation is backed by real-world performance. For a part this critical to how your AR runs, that pedigree is worth every bit of the peace of mind it brings.

Frequently Asked Questions
What length barrel does the Wilson Combat pistol length gas tube work with?
Pistol-length gas is the shortest system on the AR platform and is generally used on shorter barrels, often in the 7 to 10 inch range. The key is that your barrel's gas port has to be positioned for pistol-length gas. Always match the tube to your barrel's specified gas system length rather than the barrel length alone.
Does this gas tube come with a roll pin?
No, the roll pin is not included with this tube. You'll need a gas tube roll pin to secure it to your gas block during installation. If you don't already have one, it's an easy and inexpensive part to add to your order.
Is the Wilson Combat pistol length gas tube truly mil-spec?
Yes. It's a genuine AR-15/M16 gas tube made to military specifications by a government contractor, so it matches the tolerances and materials the platform was built around. The mil-spec stainless construction gives it the heat tolerance and corrosion resistance a gas tube needs.
Can I use this tube for a new build or just as a replacement?
Both. It works as a direct replacement for a worn or damaged tube, and it's just as at home in a fresh scratch build. As long as your barrel is cut for pistol-length gas, this tube will handle the job.
