A couple weeks ago I compared a VX6, a Swarovski Z3 and a zeiss HD5 all side by side and IMHO the VX6 excelled in just about every optical characteristic. Only real difference was the robust size of the 30mm VX6. I am just not certain about it size on a lightweight rifle even though it's not all that heavy. But she is chunky! The one thing that really impressed be was the reticle on the VX6 , much better than the ones on VX3's. But in the end I bought a VX3 3.5-10x40 at less than half the price of the VX6.
