I have a very old Weaver 4x Marksman scope and still works but fogs up. The front Objective you can see the deteriorated o-ring/seal coming apart. My question is any of you have experience with trying to waranty an old Weaver? I have 2K Leupolds and some hi/dollar Burris but I kinda like this one and dont want it replaced would rather have it fixed to put on my old K98. Any of you tried their waranty on ooooold Weavers?
