Redfield as I understand is made by Leupold now. So that pretty much tells me they are good quality and have a great customer service. But I do not own one. I have looked through them at Wal Mart and the glass seems real good.
I owned a Redfield many years ago (20 or more) and it was a "Widefield" or "Wideview" model. I never hated a scope so much in my life. Granted it was nice and clear as long as you looked dead center though the middle of the scope, but move off that into the Wide field area.. and the optics went to nuts. I sent that back twice and they told me it was my vision that was causing it. Funny thing is, I went to trade the scope in on a Bushnell straight 4x40mm and the person who owned the gun store looked through it and said, the inside of that scope is off, but that's ok.. I can send it back to Redfield. I never told him it had went back twice.
