Gunsmithing Need a quick spec on a recoil lug

[Sidk]

Hey Guys, does anyone know the inside diameter of a R700 recoil lug or have one they can measure for me?

TIA

Should run 1.0625-1.063 factory. If its been blueprinted then you need to measure the barrel shank to get major on it and OD.

Thank you. I looked all over the net and couldn't find one single blueprint/drawing with the spec to save my rear. The gun is factory for now, trying my hand at making a tube chassis and needed the spec for the recoil disk.
