Being made in the same facility doesn't mean anything. The material and assembly specification can vary wildly from one product to another, even if they're made in the same facility. I've not heard of a single optics manufacturer who produces the lenses AND assembles the optics in the same facility, so you're seeing sourced lenses shipped to the same site to be assembled... Doesn't mean anything will be common among them, except Bill and Jack who assembled them.
I have heard they're made in the same plant as Vortex, Nightforce, and S&B... Which one is true, if any are, still doesn't matter...
I received mine yesterday. I'll be out of pocket for about 3wks for work before I can mount it on anything, but my wife tells me it's waiting at home when I get back there.
