Description
Getting the gas system right is what makes a short AR run smooth, and the Faxon pistol-length gas tube handles that job without drama. It's turned from bright stainless steel, so it stands up to the heat and pressure of a compact gas system while resisting corrosion over the long haul. Faxon builds these tough enough to take full-auto fire, which tells you plenty about how they'll hold up under normal range and range-plus use.
Where the Faxon Pistol-Length Gas Tube Belongs
Pistol-length is the shortest of the common gas system layouts, and it shows up most on barrels under about 10 inches. That makes it the go-to choice for 300 Blackout builds, SBRs, and AR pistols, where the short dwell time is exactly what you need to cycle both supersonic and heavier subsonic loads. If your barrel is set up for a pistol-length gas system, this is the tube that matches it. Always confirm your barrel's gas system length before ordering, since carbine, mid, and rifle tubes are all different sizes.
Why Builders Reach for the Faxon Gas Tube
Faxon has a strong reputation in the barrel and gas block world, so pairing their tube with a Faxon barrel and gas block gives you parts that were made to work together. Folks running these report clean fitment inside the receiver, gas block, and handguard, with the length coming in right where it should. The machining is clean on both ends, with the gas block side properly drilled and chamfered for the gas port and roll pin.
What the Faxon Pistol Gas Tube Includes
Every tube comes with the installation roll pin, so you're not hunting down small parts mid-build. It's backed by the Faxon Lifetime Guarantee covering manufacturing and material defects to the original owner. Whether you're finishing a fresh 300 BLK upper or replacing a worn tube, it's a simple, reliable piece that just does its job.

Frequently Asked Questions
What barrel length does the Faxon pistol-length gas tube work with?
Pistol-length gas systems are used on the shortest AR barrels, generally under about 10 inches. You'll see them most on 300 Blackout builds, SBRs, and AR pistols in the 6 to 10.5 inch range. The key is matching the gas tube to your barrel's gas system length, not just the barrel length, so always verify how your barrel is set up before ordering.
Will this gas tube fit an AR-10 or LR-308 build?
Yes. Faxon designed this tube to work with both AR-15 and AR-10/LR-308 systems, so it covers small and large frame platforms. As with any build, confirm your barrel calls for a pistol-length gas system before installing.
Does the Faxon pistol gas tube come with a roll pin?
It does. Each tube ships with the installation roll pin needed to secure it to your gas block, so you have the hardware on hand when it's time to assemble your upper.
Is stainless steel a good choice for a gas tube?
Stainless holds up well to the heat and pressure a gas system sees, and it resists corrosion better than plain steel over time. Faxon rates these tubes to handle full-auto fire, which speaks to their durability under hard use. For a compact pistol-length setup that runs hot, stainless is a solid pick.
