30mm scope what size is the lapping bar?
30mm= 1.181"
Scope tube measures around 1.145"
If you were to lap using the 30mm bar the rings would be to loose/
Can some one give me a measurement from a 30mm lapping bar?
Thanks dave

Mine measures 1.181 on the button! Just measured my reamer and it too measures 1.181...

thanks, i measured the scope tube again and it was 1.181"
