If you’re building a new AR or changing the gas system on an existing rifle, you’re going to need a gas tube to make it complete. While some guys might think it’s a little too obvious to mention, Wing Tactical knows that sometimes little things get overlooked, and we’ve got your back with a quality selection of gas tubes to fill the needs of every armorer. If you’re building a custom rifle and want to add a special touch, a quality Nitromet finished WMD Gas Tube may be just the addition you’re looking for.

Why Nitromet?

Nitromet is a next generation Melonite finish that provides a better wear profile than standard melonite coatings. The surface is harder and features a self lubricity that helps it stay clean. That reduction of dirt and fouling keeps your rifle cycling smoothly which relieves you of excess cleaning and maintence chores.

Using a coated gas tube rather than leaving the metal raw gives it a truly custom look too. The sleek blacker-than-black of Nitromet is the finishing touch you want. It won’t scratch easily, and resists corrosion and fouling for the life of the components it’s used on.
