Troy Folding Battle Sight Rear, T6 Aircraft Aluminum - Black FBS-R0BT-00
Great rear sight. I use the standard AR front sight and the Troy Co-witnesses through my EO Tech. When folded, it fits under the magnifier perfectly. Apertures are adequate even for the old man's eyes! Bulletproof sight...as sturdy as they come. A little expensive compared to other name brand comparible sights, but still worth every penny.
Cons: A little expensive
