It all depends on your daffynition of 'high'. It could be 12" high at 100 and be accepted. The sighting was set up for 6:00 hold on the theory that the sight blade would not obliterate the target, which is true. You aimed at the center of mass (like a soldier's belt buckle) and you got a torso hit, which means you and the carbine performed your mission. So, unless you are low, I would adjust the windage only. If you're too low, you could take the sight blade down and put the shot where you want it. Just be sure to adjust the sight blade in the specified manner so the carbine will remain in G.I. condition.
