As far as I know savage, howa, and Seekins (Havak) are the only companies putting out 6 ARC. Ruger will be number 4 that I know of. I was going to build out of a Ruger American Grendel. But started looking at other calibers like 6GT. I was at a gun shop in Woodward and we starting talking about the 6 ARC. That’s what I found out that ruger dropped the new line up and 6 ARC was in it. I own 3 Ruger Americans. I will be adding number 4 to the safe when it comes out. I will upgrade it of course.
