I would call and check with cs, then I would send it in anyway.

Here is why. My last experience with cs, I called about changing the reticle on a M8-6x and a Vari-XIII 2.5-8x.

They said they could do the 2.5-8 but the 6x was too old.

I sent them anyway, got the call and they wanted my cc# to pay for the 6x but couldn't change the 2.5-8.

So, it might work out, send it in and ask to clean, inspect, and do any upgrades under warranty.
