WMD Guns

Overview

The WMD Nitromet Gas Tube is a mid-length gas tube designed for AR-15 builds, featuring a durable nitride finish that enhances its corrosion resistance. Constructed from carbon steel, this gas tube effectively channels gases from the barrel to the bolt carrier group, ensuring reliable cycling in your firearm. It's commonly found in mid-length gas system builds, particularly those chambered in 5.56 NATO, making it a solid choice for a variety of setups.
