I have a lead on a LNIB Russian Kobra red dot for $375, I've found them for almost $500 at online stores. They look really nice and would work good on my Saiga I'm thinking but i can't find many reviews on them and haven't heard much other than they're the real deal dot sight that the Russian military uses and are really rugged. There's a thread i found here but it's 10 years old. Anyone have experience with these dots?
