If it works for you, go for it. My 12 yr old daughter just took her first buck with my AP4 .308 using a 1.5-5 VX3 set at 1.5x.
My wife's uncle said my gun had no place in the woods. In the last six years since I purchased this rifle, it has taken more deer than his traditional BAR, and one of his older brothers is now looking into an AR for hunting (he's in his late 50's).
Just remember, opinions are like a-holes, everybody has one! Go with what works for you. For driven hunts, I prefer a red dot. For everything else, I like my low power scopes.
