Introducing the Spikes Tactical SUGT0M1: a product from Spike\'s Tactical that they consider to be the superior gas tube available for your AR-15 rifle. These gas tubes are crafted from Mil-Spec 304 stainless steel and feature a Melonite coating. This coating ensures enhanced heat resistance, efficient corrosion resistance, and minimizes reflection. Designed to fit not just .223/5.56 upper receivers, they\'re also a match for 5.45 uppers, especially when firing inexpensive surplus ammunition that\'s corrosive. These gas tubes are identical to the ones installed on the renowned ST-15 rifles and all of Spike\'s Tactical\'s complete upper receivers. Each Gas Tube comes along with a Split Roll Pin for added convenience.
