I have several Midwest industries flip up rear sights with the A-2 dual aperture. In use these sights are very durable and are used in the same manner as the A-2 rear except no elevation adjustment. These sights are good out to 300 yards. I also have one of the reduced size MI fold down rear sights which I sighted in for my 6.5 Grendel. I don't have room on the top rail with my scope mount but I carry the sight in my rifle case in the event something happens to my scope. I used the MI backup iron sight behind my E O tech on my duty rifle and my dedicated 22 AR training rifle. With the way my eye sight is depreciating I don't think I could see well enough in most light to use the iron sights past 300 yards.
