If it is true CQB just use the scope as a big ghost ring or for that matter point shoot. Try this excersize at 3 5 7 10yards on an IDPA type target.
2-3 rounds as fast as possible to center mass from a low ready position. At the closest distance the target will fill up the scope. Think of it as a caveman EOTech. In every cqb rifle class I make guys run their guns with the optics turned off. Most can get hits to 25 yards without iron sights just using the scope tube as a sight. In CQB you also have to be aware of the sight offset. on a standard AR it is around 2 " with a red dot on top of a scope it's more like 3" now cant the rifle and you'll be shooting the door frame or other cover; maybe even the good guy or family member you want to save.
On the other end of the spectrum most shooters can't hit a IDPA target at 600 yards with iron sights and a large percent can't do it with their scope. Add in factors like wind, humidity, alltitude, temp changes and standard scopes then a shooter that does well at 100 is lost at 600. I see it in every class.
Then there was the slap in the chops on the closed eye side. IF YOU HAD THAT EYE OPEN YOU WOULD HAVE SEEN THAT COMING YOU SON OF A B****!!!!
