Rings are manufactured by ertel, owned by hastings. they SHOULD be made in Canada. Nothing wrong with that set, as long as you install the rings with the pip marks up and the top ring in the top groove with the letters "top" up. The OP just wants piece of mind, so I suggested he double check with the machine shop. It's not that complicated.I shouldn't have even mentioned reverse torsional rings, it only muddied the waters, but he wanted to know if the bevel faces the opposite direction in the second groove. It doesn't in this ring pack.
