Lifetime warranty regardless of second, third or forth user and no receipt required.
Best to contact Leupold Service Centre directly in the states... look on their website and go from there.
I had a faulty rangefinder from them a few years back where it wouldn't range to the specs as it should have so I contacted them, they replaced it free of charge where i eventually sold the replacement and bought a Leica and never looked back!
