The gas tube is one of those parts nobody thinks about until it goes wrong, and Faxon built this one to keep it out of your mind for good. It's a rifle-length tube cut from tough stainless steel, and Faxon rates it to handle anything you put through it, up to and including full-auto fire. The bright stainless finish gives it real corrosion resistance, which matters on a part that runs hot and lives inside your upper for years.
Rifle-length is the original AR gas system, traditionally paired with 18 to 20 inch barrels where the gas port sits roughly 12 inches from the chamber. That longer distance means lower port pressure and a longer dwell time, which translates to the smoothest, softest cycling of any of the standard lengths. If you're putting together a DMR, a precision rig, or a classic full-size 20 inch rifle, this is the tube the build was designed around. Just make sure your barrel is actually drilled for a rifle-length gas system before ordering, since matching the tube to your gas port location is what keeps everything cycling right.
One of the handy things here is that this Faxon tube works with both AR-15 and AR-10/LR-308 platforms, so it covers small-frame and large-frame builds without you hunting down a different part number. Folks running a matched Faxon barrel and adjustable gas block tend to grab this alongside them to guarantee everything mates up, and the fit and machining get consistent praise. The gas-block end has precision drilled and chamfered gas and pin holes, and the receiver end is properly flared to seat clean.
Installation is straightforward for anyone comfortable with a punch and a bench block, and the required roll pin is included in the package. Faxon also backs it with a lifetime guarantee covering manufacturing and material defects to the original purchaser, which is a nice bit of reassurance on a part you want to install once and forget about.
Rifle-length gas systems are traditionally used on AR-15 barrels in the 18 to 20 inch range, with the gas port sitting around 12 inches from the chamber. The most important thing is that your barrel is drilled for a rifle-length gas system, so check that before ordering. Matching the tube to your barrel's gas port location is what keeps your rifle cycling correctly.
Yes. Faxon designed this stainless tube to work with both AR-15 and AR-10/LR-308 platforms, so it covers small-frame and large-frame builds with one part number. As always, confirm your specific barrel uses a rifle-length gas system.
Stainless resists corrosion better than phosphate-coated or untreated steel, which is a real plus on a part that runs hot and stays inside your upper for the life of the build. Faxon also rates this tube to handle full-auto fire, so durability isn't a concern. It's a set-it-and-forget-it upgrade for high round count and outdoor rigs.
The installation roll pin comes in the package, so you won't need to source one separately. Installation is straightforward if you're comfortable with a punch and a bench block. The gas-block end holes are drilled and chamfered and the receiver end is flared, so it seats clean during assembly.
