Thanks for your write up.

I have one of the older ZA3 3-9 scopes from when they first came out. The focus turns easy and as you say the eye box is not big as you say. This scope has been shot 400 plus times and been on-off the rifle in an attempted scope swap. It rides in Talley LW rings and held zero for at least 3 years, I forget when I bought it. This year I took it off and did have to re-zero it when i put it back on. It is a moderately good scope for moderate money. I have NO idea if the new ones are still good. The 30 mm jobs should be OK I guess.
