Same glass, which is to say excellent glass, noticeably better than the VX-3 series, very light for the magnification, but I broke all the erectors on mine (or on the ones I dialed). After getting Leupold to repair them, I sold them on Ebay. I broke 3 in total, 2 VX-6's and 1 VX-5.
Sucks because glass is not as clear as the VX-5's and 6's, but I went to NF and SWFA as most folks have. Also Sightron. The bullets always hit where you expect them to.
But if you're not dialing much...
I'm not a real hater and still use some Leupolds (though never for dialing) on rifles which have flattop actions or bases I've bedded in a jig. The tubes are thin are very susceptible to even minor misalignments in the front and rear bases. Which is why a scope can work perfectly for years on one rifle and crap out immediately when you put it on another rifle.
Just my two cents. Worth what you paid for it.
