WMD Guns
Overview
The WMD Guns AR-15 Gas Tube features a nitride finish that enhances durability and corrosion resistance, while the carbon steel construction ensures reliability under various conditions. Designed for a carbine-length gas system, this gas tube effectively channels the gas from the barrel back into the action, optimizing performance for your build. This component is commonly found in builds using a carbine gas system and chambered for 5.56 NATO, making it a staple for many AR-15 configurations.

Reviewed on April 25, 2026Verified with Build
WMD Guns Nitromet carbine length gas tube works as advertised. Pin alignment was correct. The dark nitride finish resists carbon buildup. Cycles a 16 inch carbine without any issues over a few hundred rounds.

nitromet finished carbine gas tube, properly drilled and straight. roll pin alignment on the gas block side was dead nuts on my install. WMD coatings are slick which is the selling point

WMD Nitromet carbine length gas tube has the dark nitride finish. Slight color variation versus my other carbon-blackened parts when in good light. Function is correct on a 16 inch build. Pin alignment was tight which is good.
