Okay, so my dad came down to visit me from Missouri (i live in Texas) and he was trying to be nice so he bought me a scope that Ive been needing for my SD700. Well i get home and try to put it on and find out that the scope he bought me doesn't fit with my weaver rail. Does anyone know what i can do to fix it? I can't take it back because the place he bought it from has a strict no returns on open box policy. Help?
