had one scope "go south" on me, a Bushnell Banner that came stock on a Beeman air rifle. It worked OK, but the magnification ring would never move. So, I sent it back to Bushnell,and used their little known option of upgrading to a better scope rather than having that one repaired or replaced. I gave them a pittance to upgrade to a much nicer Elite 3200 tactical (5-15,target knobs, mil-dot reticle.)
The Bushnell Elites are almost universally well spoken of, the 3200's don't cost an arm and a leg, and with this kind of warranty coverage,anyone else is going to have a difficult time getting my buisness !!
