The marketing dude from Swamp Fox laid out how they came to be on another site early last year. Some un-named China is asshoe optics factory who OEM's for several companies decided they wanted to go direct to consumer and Swamp Fox Optics is that vehicle. Someone involved has Army SOF ties and that's behind the naming convention.
ETA: On the gram they show SF guys OCONUS running the Arrowhead LPVO's on various blasters.
