For years I ran a reg AO 3-9x Vari X ii.
Normal rings.
Varmint rig, summer.....not bundled up.

Deer rig was RSI w m8 4x.
Used an ext ring at rear. Only needed a bit.

Another B model w a reg 3-9x Vari X ii.
Offset again at rear.

Have another B w Vari X iii 3.5-10x.
Yup, it will get an ext ring at rear.

My neck just doesnt work like it used to.
