LBE Unlimited ARGTR AR-15 Rifle Length Gas Tube Melonite Black

The LBE Unlimited ARGTR is a rifle-length gas tube machined from 304 stainless steel seamless tubing and finished in a durable black Melonite coating for outstanding wear and corrosion resistance on your AR-15 platform rifle.

Engineered to channel propellant gas from the barrel's gas block back to the bolt carrier group, this rifle-length gas tube is purpose-built for AR-15 rifles set up with a rifle-length gas system. The Melonite (salt bath nitride) surface treatment hardens the outer surface, reduces friction, and shrugs off corrosion far better than a standard phosphate finish, making it a smart upgrade for hard-use or precision rifles.

Installation is straightforward - the tube slides into the gas block and is secured with the included gas tube roll pin. Manufactured by LBE Unlimited right here in the USA, the ARGTR gas tube delivers the durability, dimensional accuracy, and consistent fit needed for reliable cycling on any properly configured rifle-length AR-15.
