I received a used Cmore sight with flat top adapter in a trade but know nothing about them. I would rather have a carry handle for my 9mm upper ( which is what the Cmore was on). The Cmore is used and shows signs of use but does not look abused. Everything appears to function as they are supposed to. I am at work and can send pictures to anyone interested but it will be in the morning. I do not have any experience with these sights so I just want to trade it off. I am not trying to pawn off a lemon I can assure you of that. Even if it needed minor work I think this is one of heck of a deal. Let me know if interested. A manual is also included.
