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.
