Understanding Parts of a Technical Drawing

Hi, I'm a SolidWorks hobbyist. I want to model this (Pin for AR-15 Hammer and Trigger in inches), but I am stuck on trying to understand the middle part (circled in red).

What does R.030 X Ø.125 mean? I know it's a circle with a diameter of 0.125 inches, but what is the radius symbol referring to?

Also, what information is in the hexagonal symbol?
