Last night at our monthly Deerstalkers club night our guest speaker was a guy who runs a small business making sound moderators from stainless steel and as NZ has only a population of four and a half million most of his out put goes offshore. 40% going to the UK.
From what he told us the Police in the UK refused a rifle owner permission to acquire a sound moderator on the grounds that he couldn't give good cause for requiring one. In the Uk you have to belong to a rifle club for target shooting or own land or have access to land to own a rifle and they are not going to give you a license for a 308 just to shoot rabbits.
It would appear this chap took the Police to court to be able to own one and won his case claiming loss of hearing and since then the Police have not had a reason to refuse ownership of one, although it still has to go on your license.
I used to have a Parker hale one on my little Greener martini for rabbit shooting forty odd years ago when I lived in England. Still got it, one of the best made.
In NZ we can just buy one off the shelf, no restrictions.
