MAGPUL MBUS Flip-Up Sight Set for AR-15

Low-profile, flattop-mounted polymer sights deploy instantly at the touch of a finger to provide backup sighting if a primary optic fails. When folded, contour prevents snagging on brush, sling, or gear. Spring-loaded ambidextrous release mechanism lets you hit the grooved tab on either side of the sight to deploy and lock it in place. Hitting the same tabs retracts the sight when you're done. Uses less than 1 inch of MIL-STD 1913 Picatinny receiver rail space and locks securely in place with the included steel crossbolt. Provides the same height over bore as standard A2 iron sights. Rear sight is windage-adjustable with two apertures: large 0.185 inch peep and small 0.070 inch peep. Front sight must be mounted on a railed forend on the same plane as the receiver rail to witness correctly with rear sight. Not compatible with railed gas blocks or MOE handguard.
