A rifle-length gas tube is one of those AR15 components that rarely gets attention until you need it—and then you're grateful it's built to last. The LBE Unlimited rifle-length gas tube is a direct impingement system part machined from 304 stainless steel seamless tubing and finished with Melonite, a surface treatment that resists corrosion and wear. If you're building or rebuilding an AR15, replacing a damaged tube, or simply want a domestic-made alternative to generic imports, this is the kind of part that works quietly and reliably downrange.
LBE Unlimited manufactures their components in the United States, and that shows in their approach to quality. This gas tube is straightforward—no marketing fluff, just the engineering needed to route expanding gases from your barrel to the bolt carrier group. The Melonite treatment provides real durability in harsh conditions, whether you're running suppressed fire, high round counts, or extended field use. Paired with a quality upper receiver and bolt carrier group, a solid gas tube is part of the foundation of a reliable rifle.
The included roll pin simplifies installation. If you're an AR builder who cares where your parts come from and wants components that won't let you down, LBE's domestic manufacturing and attention to material selection make this a sensible choice for the upper end of your build.

Frequently Asked Questions
What platform does this gas tube fit?
This is a rifle-length gas tube designed for AR15 direct impingement systems. Confirm your upper receiver's gas system length before ordering.
What's included with this gas tube?
The gas tube ships with a roll pin for installation.
Why choose a stainless steel gas tube with Melonite finish?
Stainless steel resists rust and corrosion inherently. The Melonite surface treatment hardens the steel further and improves wear resistance, making the tube more durable under sustained fire or in wet conditions. It's especially valuable if you shoot suppressed or log high round counts.
Is this made in the USA?
Yes. LBE Unlimited manufactures this gas tube in the United States.
