Hello,
The turn around time is up to 4 weeks. If the optic moves even the thickness of a post a note that may cause up to 4 MOA of shift at 100 yards. Lapping the rings usually voids the warranty but that's on NF rings I don't know Seekins policy. Setting the diopter is crucial to getting the most out of your optic. Anytime you have a question or need help with your optic please give NF a call 208-476-9814 ext #3. I hope this helps.
