Aperture or peep sights for a Mauser 96

I'm looking for some, Anyone got something for sale in NZ? Or know where something might be? Lyman or Williams? Pros or Cons of different types?

I month or so back I was at Upper Hutt gun shop and they had a small handful of 2nd hand aperture sights there, most of them were for model 94 lever action rifles, but there was one or two there for bolt actions, its worth checking out.

I've got a parker hale one of a 98 looks like it would fit a 96 too.Needs a longer foresight

Thanks guys but @Tentman has sorted me out. I just need to get it too a gun smith. Thanks.
