I was just recently given a Kenco Arms multi caliber EH15-4 upper/lower. I was wondering what exact calibers I could build with it. I was told any 308/338/6.5 creedmoor would be a no go.......but a .50 beowulf would be okay. That confused me. Is it b/c the above mentioned use ar-10 assemblies or is there something I am missing? any help would be appreciated.
