I need sights for a fwb 602. Should I buy the original fwb sight or is there something else out there that works well?

Not sure about availability in NZ but Centra makes some very solid sights that will clamp right onto the FWB.

I shoot a Hammerli 460 sight on my similar era Model 601, those can be hard to find however.

For 10m work even the recent FWB sights are not too bad.

What is available in NZ might be the bigger issue.

We are quite lucky here to have several sources of imported bits or importers.
Try the guys at Shooting stuff they do handle Feinwerkbau gear I think.
Or put a question on the NZ web site Smallbore Rifle Target Shooting Talk.
