Trying to do some homework on the best possible way to mount a 3-9X40 scope on my flat-top (no carry handle) AR-15. The scope is a one inch tube and I seem to find many mixed reviews on the proper way to mount it. Specifically, will the factory installed front post sight get in the way of the sight picture when looking through the scope? Some say no and others say to raise the optics with risers that you would affix the scope mounting rings to. I'd like to focus on the proper height of the mounting rings, the need for any riser, and whether or not the front sight post will be in the way when viewing through the scope. I appreciate any help one can offer.
