Simply put, this scope is beautiful. The description says it all; the objective lens diameter, the multiple zooms, the lens coating (ruby, by the way. it is dark, inconspicuous, and downright sinister-looking ). What more could a sniper want? Oh, I know: multiple settings of cross-hair illumination. And this scope has not 5, not 10, but 11 settings of brightness! Because when there's those times in which 10 is just not enough illumination and you need that EXTRA kick, this one goes to ELEVEN!
But I know what you're thinking; "Why not just make 1 brighter that way 10 is proportionately brighter as well?"
... ... ... ... But this one goes to ELEVEN...
-High diameter objective lens
-Comfortable eye relief
-See through lens covers (one being in a yellow hue to increase contrast which is PERFECT for sniping)
-Multiple levels of illumination (IT GOES TO ELEVEN!!!)
-None. This thing is the epitome of airsoft sniper optics. Anything more would be overkill even for a +500fps gas sniper.
