Scope rails were 13mm to 11mm, I think Hiller got his dimensions muddled.
Hi Coburn

The safety dates were going to be my next question as I was wondering today whether they coincided with the scope rail change and piston seal change.

Hillier could have measured the scope rails in the cutout instead of their widest point which would explain the difference in dimensions.
