Optics are vastly superior to iron sights until those optics malfunction or fail.
In the event of optic failure, backup iron sights (BUIS) offer a critical redundancy in the AR platform. Some BUIS can be deployed instantly. With a press of a button the sight flips up and locks into place, allowing an operator to continue with the mission and stay in the fight.

The sights are spring loaded and held in place by a quick-release lever that also ensures the sights are not accidentally deployed. These sights lean slightly to the rear, so they fold back in the correct position if accidentally dropped. The rear sight has dual apertures for different engagement distances.
