I'm putting together another precision 5.56 gun and I'm trying to figure out if scope technology has produced new stuff that would warrant the extra $$ over what I'm used to. I am running a 3-15 vortex viper FFP scope and have no complaints. I see Steiner, NF, Leupold, and a few others have similar magnification scopes but without looking through one its hard to judge by a spec sheet. I don't need more magnification as I'm only shooting 1000-1200 yards max. Have I got a good scope or is there one better out?
