LBE Unlimited ARGTM Gas Tube Mid-Length 304 Stainless Steel AR-15

The LBE Unlimited ARGTM is a mid-length gas tube built for the AR-15 platform, replacing or upgrading the factory gas tube on a standard AR-15 upper assembly. Designed for mid-length gas systems, this tube routes propellant gas from the gas block to the bolt carrier group to cycle the action reliably.

Constructed from 304 stainless steel seamless tubing, the ARGTM offers excellent corrosion resistance, dimensional consistency, and a smooth bore finish for reliable gas flow across a wide range of shooting conditions. A natural stainless steel finish keeps the part protected and visually clean, matching other stainless components on a custom build.

Installation is straightforward: the mid-length tube drops into the upper receiver gas channel and is locked in place with the included gas tube roll pin, which seats through the receiver to keep the tube from shifting during firing. It is made in the USA and built to fit standard AR-15 upper receivers with a mid-length gas system configuration.
