The Brownells AR-15 Gas Tube in carbine length with black nitride finish is a direct replacement component for your AR build or maintenance cycle. This stainless steel tube handles the critical job of routing high-pressure gas from your barrel into the bolt carrier group—whether you're running a precision rifle, duty gun, or hunting platform. The black nitride coating goes beyond looks; it's engineered to resist corrosion, reduce wear from repeated cycles, and improve fatigue strength under sustained fire.
Carbine-length gas systems strike a balance for most AR builds. They're shorter than rifle-length tubes (found on 20-inch barrels) but longer than mid-length, creating a gas dwell time that works well with standard 16-inch barrels and keeps the action running reliably without excessive bolt carrier speed. If you're swapping out a worn tube, building a new upper, or just want a premium stainless component with corrosion-resistant finish, this is a straightforward upgrade.
Black nitride has become the go-to finish for AR internals because it holds up to solvents, suppressor blowback, and the salt spray environment—whether you're in the mountains or near the coast. It's aesthetically cleaner than raw steel too, matching modern AR builds without the need for additional finishing.
Note that the roll pin required for installation is sold separately, so plan your build accordingly.

Yes. Carbine-length gas tubes are designed for standard 16-inch AR barrels and provide reliable dwell time for proper cycling.
Black nitride increases corrosion resistance, wear resistance, and fatigue strength. It also provides a clean, modern appearance that resists cleaning solvents and environmental corrosion.
No. The roll pin is sold separately, so you'll need to source one for installation.
No. This is carbine length only. Brownells offers separate carbine, mid-length, rifle-length, and pistol-length options—verify your barrel length and desired gas system before ordering.
