In referance to a Leupold VX 3i .. I can for sure give it very favorable recomendation. I have a couple of them mounted in the gun safe.
One on a Rem BDL 300 Rum and the other on my pretty rare M-70 Mannlicher in 30-06.
Having 7 Leupolds mounted in the safe from 1.5x5 thru 6.5x20 , those 3.5x10 VX3i's have quickly became my favorites... They do it all for me.
BTW, I do have one AR "Saint" wearing a Vortex Strike Eagle 1x8 and IMO, it's glass comes no where close to even a VX 1 Leupold in clearity and quality. ...
