Based off of the AR-15/M16 front sight, the Magpul MBUS front flip up sight is a durable color-injection molded folding back up sight. It conveniently folds down and locks into place but flips up with just a press of the button. Elevation adjustable, quickly mounts to any mil-spec 1913 Picatinny rail.

Pair it up with our Magpul MBUS Rear Flip Up Sight (ARR-850).

NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed fore end on the same plane as the receiver rail.

Made in the USA.
