Thread: Leupold scope ring screws

Can any one help me source some replacement cap screws for Leupold PRW2 scope rings. The screws which clamp the ring to the rail are the main ones I am after. I am fairly certain these are 8-40.
The original one have a sort of dome head on them with a quite shallow Torx slot which makes them very easy to strip out. I can find these off shore but at very high prices, or on amazon which will not ship them to NZ because they classify them as a "firearms part"
I don't live in a main centre so can't just rock up at the local engineer supply shop, I would like to source these in NZ and online. Any help appreciated.
