Just thinking about this and it seems to me that the real issue would be getting a decent undrilled .300BLK barrel and having it turned / profiled to fit the Krink. Everything else (bolt / carrier / mag etc) would be the same. So I would think if you can source the barrel the rest should fall into place with a good gunsmith and some patience. That said, I am not sure who has barrels these days. I like this round and the only concern I would have is I cant seem to find any .300Blk these days at any price, let alone a price for range use.
