Similar to the standard Knight's Armament Micro Flip Up Sight but they mount at a 45 degree angle to clear a scope. Sights are mounted to a base plate that attaches to a standard MIL-Spec 1913 Picatinny rail with one set screw. Designed to be mounted to a flat top upper for the rear and to a railed hanguard for the front sight. Both sights fold down out of the way. Front sight is adjustable for elevation and rear sight is adjustable for windage. Rear sights used standard Knight's Armament peep insert that is removable for a larger aperture. Both sights are held in the up and down position by a spring detent, they do not "lock" up, this allows for easier manipulation as there are no buttons to push, simply fold the sights up or down.
