LBE Unlimited ARGT308 Gas Tube Mid-Length 304 Stainless Steel AR-10

The LBE Unlimited ARGT308 is a mid-length gas tube built specifically for the AR-10 platform chambered in .308 Winchester. It is machined from 304 stainless steel seamless tubing, giving it excellent resistance to heat, corrosion, and carbon fouling during extended firing sessions.

Designed as a direct replacement or upgrade component, this mid-length gas tube routes propellant gases from the gas block to the bolt carrier group, cycling the action reliably. The natural stainless steel finish matches other stainless components on a build and provides a clean, corrosion-resistant surface. A gas tube roll pin is included for installation.

Like all LBE Unlimited components, the ARGT308 is made in the USA and manufactured to precise tolerances so it drops into standard AR-10 upper receiver gas tube channels without fitting issues. It is an ideal replacement for a worn factory tube or as a quality upgrade during a .308 AR build.
