The page says made by Axiom the optic in the photos with the T81 it does not match the stock optic photo or any known legitimate model.
The one photo'd on the T81 appears to be in the exact style of chinese clones but lacking the manual on/off dial. So we are waiting to hear back from TI if this is a new revised model of Kobra or something else.
There are very few other US and RU sellers showing this new model which does not appear on Axiom's web page. These new models seem to have appeared around 2019 but there is very little information and only an handful of written reviews.
