I have NF Tract Meopta Zeiss Swarovski Weaver, out of all, the Swarovski is the clearest brightnessI have a variety of scope on my rifles. Off the top of my head, I currently have; Leupold, Burris, Nikon, TRACT, Mueller, Meopta, Primary Arms, Truglo. If I could justify the cost, I'd put Swarovski glass on all my scoped rifles.
