Meprolight tru-dot - Meprolight Tru-Dot Red Dot Sight

I ordered this sight and received a lesser model (different UPC and part number 56860004) that it didn't even worked. So, I returned it for an exchange and received the same wrong Meprolight. After a tedious waiting and several phone calls, I got to talk to a Supervisor. According to Optic Planet, the tru-dot sight had been discontinued. Therefore, the one sent is the same, really!!! Anyways, do not order it. Get the newer version tru-vision. Hopefully, optic Planet won't substitute it for a lesser model!
