Tell your gun shop owner I'll take all the working Redfield scopes he has for $10.00 and I'll pay shipping.
No doubt the mid-range scopes of leupold, Nikon, and a few others have better glass now but your paying $200-350 for them. All I'm saying is those older Redfileds were top quality then and very serviceable for todays hunters now. If you can locate a clean 3X9 widefield for under a 100$ you can't go wrong. It will stand up to anything you can put it on.
