It is a cromoly vandium barrel. I would consider it medium contour. I put this gun together 3 three years ago. Sabre was one of the top barrel makers for grendel as well as many other AR barrels at that time. ATF shut them down and they are not in business any longer as far as I know (another story). At the time of my build I did a lot of research and ended up going with Sabre based on reference from many good sources. I got the Barrel from Tactical Coordination. They have a website if you are interested in checking them out. I called and talked to the Sabre technicians at the time of the build and they told me this barrel was undoubtedly their most accurate barrel. More so than their 24" or 20". Thats why I chose it.
