Have a rifle with iron sights; put weaver two piece bases and medium height rings on. Right now, the bottom of the scope is right at the top of the sights). So far, I have excellent jaw weld... I wanted to have sights on it as a backup in case the scope dies, but that has created its own issues. What are my options? Can I bring the scope down lower or will the iron sights begin to mess up the sight picture in the scope? Do I just need to get a cheek piece to raise my eye up to where it needs to be? Are there any iron sight options? Not sure where to go from here. Main criteria is that I keep the sights and scope. Thanks.
