I was considering mounting the weaver #93 scope rail on my Benelli and I noticed the screws on the top of the receiver have no slots to remove them. They look like plugs. How do I remove them? I have ghost ring sights so, will the scope mount fit with no modifications? What I am wondering is if the screws are there and when the factory coated/painted the receiver, it coated the slots. Any input from anybody?
