I am lowering my Opinion of Vortex Optics. See http://www.longrangehunting.com/forums/f18/vortex-viper-pst-scope-never-61015/ My Viper 2-7x32 BDC is still a really nice scope but I've had three experiences since that are BUGGING me. 1. The Vulture Bino's I sent back for collimation/focus issues have been replaced with better but not perfect bino's. Still a little issue for me when I wear glasses. 2. I bought a Viper 6.5-20x50 with the Target Dot reticle. The optics are not nearly as nice as the 2-7x 32 ( Basic Bushnell quality) and You cannot see the dot in any light but full sun. This makes it pretty much worthless for coyote or varmint hunting. This one really burns my ---. 3. My good friend Paul need a scope (quick) to take his son on a SC deer hunt. When asked about the best I could do on short notice and ~$200 I turned him on to Vortex. Told him I really liked my 2-7x and he couldn't go wrong with the warranty. I was wrong. He chose the 4-12x 50 Crossfire model (so he wouldn't have to change rings etc.) on Overnight delivery. Setup, bore sight and fire to zero the morning before they leave with no issues. Day one of the hunt his son see's a nice buck at ~200yds. Fires 6 shots while the buck dances around and finally run's off. Fires 2 shots back at camp to find scope is several FEET high and WAY right. Try to adjust the elevation when the entire Knob and internal workings of the scope come up and out. Needless to say my name is mud. All of the sudden the Lifetime warranty doesn't make me feel so good. He's sending it to me to deal with the return...which I agreed.
