Yes, in my opinion the ruggedness of the scope and the adjustments are worth the extra cash. I hate to miss stuff period. At least when you have some of the best pieces of equipment you dont have anything other than your self to blame for a miss.
So when the bull of a lifetime comes bouncing into the scope, it then shows if you are ready not if your equipment is.
I dont know who ever came up with the imaganary word of "Over Gunned"
