I have VXIII, VX3 AND VX3i and I can't tell hardly any difference between them, The VXIII
damaged by my GS( broke tube) and they said send it to them I explained it was dropped and
they replaced it with a VX 3. The scope was 25 yrs old. Leupold's CS has always been super to me.

Thats my 2cents

Anyone that doesn't learn something new everyday has their eyes and ears closed with their mouths open.
