I think the threads you found about the Trijicon being the Meopta are about the older Trijicon spotter. This new one is very different. Meopta does not offer a 20-60 eyepiece, unless they made one specifically for Trijicon. Meopta also does not have the typical gross and fine focus controls, they use barrel/helical focus.
But yes, the Nightforce and Meoptas are the same. Nightforce TS-80 = Meopro 80. Nightforce TS-82 = Meostar S2.
The only 20-60x82mm scopes with dual focus control I can find are the Zen Ray and Sig Sauer. Maybe I'm missing one? The other options is Meopta is just making a totally different design specifically for Trijicon. In any event, I have a message to Trijicon asking. I doubt they'll answer though.
Again, I was just curious. And this is all speculation anyway.
