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.
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.
