As with some other KORSAK lasers it most likely has a power adjustment that puts the brightness in the IR range, but it is not invisible to the naked eye, just very faint. I have been trying to find one of these for some time now, and I think it is a mistake for Belomo not to restock them, they would probably be sold out immediately because of the demand in the U.S., but if they want be lame and not restock, then they can LICK my KORSAK.
