Description
The gas tube is one of those small parts nobody thinks about until it stops doing its job. On a direct-impingement AR, it routes hot gas from the gas block back into the receiver to cycle the action, so it needs to hold up to heat, fouling, and years of use. Strike Industries built this one from 304 stainless steel at a true pistol-length 6.75 inches, giving you a corrosion-resistant part with mil-correct dimensions that drop right into place on the right build.
What Sets the Strike Industries Pistol-Length Gas Tube Apart
Stainless steel earns its keep here. The smooth surface sheds carbon and cleans up faster than a Parkerized tube, which matters on short gas systems that run hot and dirty. It also resists rust and pitting over time, so this is the kind of part you install once and forget about. Strike makes their tubes in all four common lengths, and this 6.75-inch version is specifically cut for pistol-length gas systems found on short-barreled uppers.
Fitment and the Oversized Roll Pin
Every tube ships with a roll pin measuring 0.312 by 0.081 inches. Strike sizes it slightly oversized on purpose, so it locks in with solid retention across most gas blocks on the market. If you happen to run a block with a tighter pin hole, the pin can be dressed down to fit. Builders have reported clean installs with common low-profile blocks, with the pin seating properly and the tube staying put where it belongs.
Whether you are finishing a fresh pistol-length upper, refreshing a tired tube, or just want a spare in the parts box, this is a straightforward, well-made piece that does exactly what it should. It is proudly made in the USA and backed by a brand that lives and breathes AR components.

Frequently Asked Questions
What barrel setup does the Strike Industries pistol-length gas tube work with?
This 6.75-inch tube is made specifically for AR-15 and M16 uppers running a pistol-length gas system, typically found on shorter barrels. If your barrel is set up for pistol-length gas, this tube matches those dimensions. Always confirm your build uses a pistol gas system before ordering, since carbine, mid, and rifle setups take longer tubes.
Does the gas tube come with a roll pin?
Yes, a roll pin measuring 0.312 by 0.081 inches is included in the package. Strike sizes it slightly oversized so it holds securely in most gas blocks on the market. If your gas block has a tighter pin hole, the pin can be filed down slightly for a proper fit.
Why choose a 304 stainless steel gas tube over a standard one?
Stainless steel resists corrosion and holds up well to the heat and carbon fouling that build up in a direct-impingement system. The smoother surface also wipes clean faster than a Parkerized tube, which is a nice bonus on hot-running short gas systems. It is a durable, install-and-forget kind of part.
Is this Strike Industries gas tube good for a first-time AR build?
It is a solid choice for both new builders and folks replacing a worn tube. The mil-correct dimensions mean it drops into a properly spec'd pistol-length upper without fuss, and pinning it in is a straightforward job with basic tools. Builders have consistently reported clean, trouble-free installs.
