the new VX6 in 1-6x24 I bought last year seems OK, I don't twist turrets a lot, glass is good, reticle is black, a bit tuff to turn the power dial, less distortion at 1X than an old NF NXS 1-4 had, illumination is really good but I wish it were a dial instead of a scroll button, mechanically don't know as its been on a 5.56 gas gun, there it has remained zeroed for 5 months.
