I've never seen any photos/videos from scion monoculars, what I've seen from boson320-based Flir breach was quite ugly) so modern Flir is not best choice imo. ATN/AGM are Chinese-made with American sticker and maybe firmware, Trijicon or N-Vision are all-American but cost extra, when i was reading ar15 it was mostly Pulsar vs locally branded Infiray debates) if you are fine with moderate size and ready to spend about 4000$ its helion xp2 50 pro vs infiray zoom, if you go a bit cheaper its axion xq 35 2 vs finder fh/fl35. I own helion xp2 50pro and xp50, recommend both, saw images from helion xq1 xq2 xp2 axion xq38 xq2 35, would recommend only xq1 if found really cheap or axion xq2 if you need smaller size. From Iray i have fh25, consider selling it, dont like built-in battery and low sharpness. saw good images from zoom and fh35 but still like Pulsar more, due to my specific needs and habits)
