Hi All,

I can't find a HW30K to view locally, so I'm unsure of a couple of details.

The 30K doesn't have open sights, but I don't know whether the breech block is drilled and tapped to accept an iron rear sight, or is it undrilled like the HW80K, HW90K etc models?

The 30K has some kind of muzzle break attached, but I don't know whether it's attached via 1/2" UNF screw thread, or grub screw, or permanently fixed?

I'm considering customising this rifle and these are key factors, so advice will be gratefully received before I commit.
