I've got an older V16 that's seen use on a couple of 223s, and is currently residing on a custom M52 Winchester sporter. Have never had an issue with it, though it's been awhile since I've shot behind it, so I've never directly compared its optical quality to that of the two Vortex Viper 6-24x50 PSTs I have on LR tactical rifles.
The Vortex scopes have nicer turrets, a low-budget zero stop, and very usable reticles. They're more comparable to Weaver's 30mm 3-15 & 4-20 Super Slam & Tactical scopes, though IMO, the glass in these Weavers is every bit as good as - probably better than - that of the Vortex PST's. Too bad Weaver didn't put as much thought into their reticle design as they did in the optical & mechanical quality of their Super Slam & tactical lineup.
I've also got two of the big 34mm tube 6-30x56 Weaver Tactical scopes, and they're awesome when it comes to optical quality. They also have a really well-designed zero stop, excellent turrets, and very good illumination - but again, they skimped on reticle design. It's beyond my comprehension why they'd invest the time, $$$, & effort into the design of a scope that's obviously plenty good enough to compete in this market segment, then fall short on the reticle design.
eta - Forgot to mention that I also own a Bushnell ET35215GZA (34mm, G2DMR, 10 mil turrets, zero-stop) and a couple of Kahles K624i AMR scopes that I'm comparing the Weaver 34mm tactical scopes to. The Weavers compare favorably to both these well-known tactical scopes, having a little less chromatic aberration than the Bushnell/a little more than the Kahles, tracking & repeatability as good as either of the others, and a zero stop that's easier to set than the Bushy, and just a little more involved than that of the Kahles. The only areas where the Weavers are lacking is in the design of their reticle, and FOV that's smaller than either of the others when set to the same magnification. Should also mention that I placed an order for one of Vortex's Gen II Razor 4.5-27x56 EBR-2C scopes a couple of weeks ago - have had the hots for one of these scopes since they were announced. According to the guys at Sport Optics, I might have it as soon as April....
