Looking for my next scope, and I think swing the almost $800 for one of these. I've currently been using a Millett 4-16 and a Vortex Viper 6-24, but even with a 20 moa base I'm mixing clicks and mil-dots. Not something I enjoy with SFP. 1. Are there any other brands I overlooked? ( ffp and adjustment range over, let's say 90) 2. How is the customer service with these brands? 3. With a target rifle, maybe I would be better served by a higher end fixed magnification?
