I’d say no.
I don’t think they federate. Least ways, I don’t think I’ve ever seen a post from a bluesky account, on lemmy or mastodon, and SDF hadn’t blocked them server side last I checked.
I think they’re a bit like truth social, not federating and off doing their own thing.
Like others have said, your best bet is to just buy new a new scope mount and rings from any firearms shop. Easier and less headache. You will need to know your scope’s tube diameter.
However, if you are dead set on repair rather than replace (and are in the US), for oddball engineering projects like this I tend to use McMaster Carr. If they if they don’t have what you need I would be very surprised. They are an engineering supplier, and have prices to match. But they sell anything thats not electronics. Excellent customer service too.
For electronics builds or repairs, I recommend DigiKey.
Between the two you could build or repair just about anything.
