I’d run it as is. Do you notice the chips when using it or as you would use it? Having someone work on it may do more harm than good.
How would having Iron Sight Inc. refurbish the scope do more harm than good?
If they didn't think that they could fix it, they would just return it with a note. They stopped working on El Paso Weaver variables because they used up much of their inventory of parts.
I've had Iron Sight Inc. work on Denver Redfields and both El Paso and Japanese Weavers and have been pleased with the quality of work that they did. They aren't fast, but they're good.
