They're made by Hakko, who also made the early Nightforce scopes. I had an opportunity to buy one for both my M14NM and 700PSS, but after checking one out on a Springfield M1A, I passed. Huge objective lens, very busy reticle, and that bubble level takes up a good chunk of the lower field of view...
