Ar-15 Flip-Up Mbus Gen 2 Front Sight - Mbus Front Sight Flip-Up Polymer For Ar-15 Black

Low-profile, flattop-mounted, polymer sights deploy instantly at the touch of a finger to provide backup sighting if a primary optic fails. Streamlined contours mean there's nothing to snag on brush, sling, or other gear when folded.
