I can't tell exactly, but it wouldn't surprise me at all if they were made in the same plant as the BX-4's. It's very common. There are only 3-4 places that make all the sub-1K bins, and they just put different wrappers and labels on them.
The Burris signature HD's? They have a significantly low FOV if the specs published are correct. 330ft for 8x42 is lowww.
