Spike's Tactical Mid-Length Melonite Gas Tube MFG # SUGT0M3 UPC # 855319005914
Spike's produced what they believe is the best gas tube out on the market for the AR15 rifle. The gas tubes are made out of Mil-Spec 304 stainless steel and then are melonite coated for greater heat resistance, corrosion resistance, and lower reflection. These gas tubes are not only great for .223/5.56 uppers but are perfect for 5.45 uppers for when you shoot cheap surplus corrosive ammunition. These are the same gas tubes that they install on their ST15 rifles and all of their complete upper receivers.
