I just got off the phone with Dave at Mueller Optics. I bought a USED 8X32 target scope, with NO original receipt. When prepairing to mount, I noticed 3 cracks on the center lense. I called the service line, and asked Dave if it could be repaired on my dime, as I did not purchase new, and did not have original proof of purchase. I made sure that under no circumstance did I expect them to pay. He told me to send in with $12 for return freight, and that they generally just send out a new scope! I am in need of a couple of varmint scopes, and now I know what they will be. 2 Mueller APT scopes. My hat's off to Mueller and Dave.
