I liked the one I bought new from the CMP so much I bought a second one.
Couple years back, they had some "used" ones for $150 with no sights. A friend went to Perry and bought two, sold one to me.
It was very lightly used. Really just had a few bumps / scrapes on the stock from handling. It cleaned up well but I went ahead and refinished the stock anyway, then mounted a 6.5 - 20X scope on it. Kept the original with the irons and use them both for different matches and plain-old fun shooting. Use them both for the rimfire matches here.
Later, a member of my club was selling his new, take-off sights so I bought them too. They're still un-used.
Adjusted both triggers as light as they go, found out they both like the same ammo and I'm a real happy camper!
IMO, the "used" or "rusted" 82Gs are among the best buys out there and I recommend them to one and all. Certainly there are higher-end rifles and likely a more experienced shooter would do better with one, but for a ham-and-egger, suits me fine.
Quite a few fellows at my club have them as well and I've yet to see one that didn't shoot.
