A while back I bought a slightly used Browning T-Bolt topped with a Weaver Grand Slam. Upon inspection of the scope, I found that the power ring was not turning smoothly. I called Weaver and they had me send it in. I think they had it for maybe 2 weeks tops. The fixed the power ring issue as well as another issue they discovered with the tracking. So I got a refurbished scope all for the cost of shipping one way. I figured that wasn't too bad for a scope bought secondhand.
