This tube is machined from 304 stainless steel and finished in black nitride. The nitride finish is described as improving corrosion resistance, wear resistance, and fatigue strength, and it gives the tube a black appearance. The raw description also notes that the tube is intended to provide consistent gas flow for proper cycling.

The tube is listed as fitting AR-15 and AR-10 rifle length gas systems.
