Trying to chose a lower power scope, around 3x9. Was looking at either the Viper 3x9 or the Mark AR 3x9. Have to keep it below $300 or so. Which one do you guys think would be the best? Or is there something else out there in that price range that would be better? It's going to be used for no farther than 400 yards. Won't be used for rangeing, just a good, sturdy, dependable scope for low money for plinking with a .223. I've done some searching on the google search, just would also like to get some opinions on some of todays scopes. I wonder if I should also add the Weaver Grand Slam in the list also. I know you get what you pay for and I'm not asking for a cheap scope with Nightforce quality. Just want something on a tight asses budget for a little back yard shooting and an occasional outlaw 3-gun. Also doesn't have to be 3x9, just somewhere in that range.
