Recently acquired one of these & will be needing a hard case. I know it's a bit of a task.
Throwing this out here for any up to date 2024 options.
With a google search so far all I can see is the (expensive) official BC Rich option:

I'm not sure UK EU retailers even keep these in stock.
This Rockcase option from Warwick:

Coffin Cases still a thing? Couldn't see any for sale in the UK.
Last option would be to have something custom made.
Any BC Rich nuts out there tackled this issue recently?
