To dress up your moderator here is a nice inexpensive way to do it . From Walmart get self stick carbon fiber vinyl wrap , I got it in black but it comes in different colors also it will definitely dress up your rifle.
If Huggett or Donny made a full length fixed shroud for the Crown in different calibers I’d buy it right now. I don’t mind fixing the shroud and putting a Donny on the end with an adaptor but a full fixed shroud would be an upgrade IMO.
