What's amazing to my is that I'm 6'6" and have no LOP issues with this rifle. In fact I usually run it a middle setting unless I'm prone. But then again, I run a "square to target" stance. I'm a N.O.T.C.H. guy and mount my scopes (cantilever mount) to fit that technique, so LOP is never really an issue for me on AR-15 pattern rifles.
I suppose that if you run a standard bladed target/hunting rifle stance it could be an issue. The primary role for my 15-22 is to train for 3-gun matches without dipping into my kids' college funds.
