I've had my Omega rifle for 3 years now, and just put on a Nikon Omega scope. My question for those who have this combo, which rings did you use? I used medium height rings, and cant get the scope far enough forward to use flip up caps, they hit the rear sight, and get proper eye relief. I really did'nt want to go with a higher ring, but I guess I will if I need to. I was thinking of taking the rear sight off. Opinions, comments.
