Some of us older guys have noticed that our arms have gotten shorter as we age. I can't see well enough through iron sights, or even through fiber optic sights, to feel comfortable that I will be able to make an ethical kill at 100 yards. So if I am hunting with a rifle, I am using a scope. I like the Nikon scopes as well, especially the Buckmaster. I have them on my Tika 7mm Rem. Magnum and my T/C 50 cal Omega. Lifetime warranty, and around $200 as I recall the last time I bought one. I also have a Nikon Prostaff that I got for less on my Marlin 30-30. It does not have as many features, but it has the same warranty and is not cheap, just less expensive.
