I have found an IOR Valdada 6-25X56 scope at my local gun shop. The owner wants me to make the first offer and I have no knowledge of this optic. I know that they are supposed to be a good euro scope with German glass, but what else? I have found them for sale on Amazon, and 2 more dealers, but I would like to hear from some users. The warranty is not like the other scopes in this price rang and I can't find an American service center. The scope has no box or manual. Please help me on this particular model scope.
