Hornady would be much better off standardizing the 22 Creedmoor. You’d sell it in many more bolt gun platforms than the ARC in an AR platform (although there was a spot for a commercialized AR 6mm cartridge). The real interest, in my opinion, is still a fast .473 rimmed .224 in a fast twist pipe.
Wrong.... Have you priced AR10 compared to AR15?? You priced building an AR10? Hell stripped lowers sell for up to $200 if you can find them. Nothing standardized on the AR10 platform. But the AR15 platform everything been standardized unless you are ruger but that’s another story..
