The line of gas tubes from Voodoo Innovations are great replacements for your old original gas tube. They also work great for that new build as well. While they are constructed from stainless steel, Voodoo Innovations coats them with their proprietary LifeCoat technology, giving them a distinct black color that either blends in with a parkerized barrel or stands out against a stainless one.
