I think the "ironsighters" are the biggest waste of money out there. I've hunted with scopes since 1967 and never had one fail. I did have three real cheap ones that had issues. Two had the inside knocked loose and actually I think that's the only issues I've had. I think if one gets a new scope free with purchase that it should be an indication of what quality to expect. For name scopes, Burris, Bushnell, Leopold, Weaver and I forget what other models I have, none have ever had issues.
If you don't like scopes then get a peep sight. It's about the fastest out there but you will have issues with it for light gathering at dusk and dawn.
