Magpul MBUS Gen 2 AR-15 Rear Flip-Up Sight Stealth Gray

The Magpul MBUS Gen 2 is a flip-up iron sight for the AR-15 platform, designed to serve as a backup sighting system or a primary sight on rifles without an optic. It mounts to a Picatinny rail and is finished in stealth gray.

The rear sight is molded from impact-resistant polymer and uses a spring-loaded flip-up design. Protective wings shield the dual, same-plane flip apertures, and a detent knob allows positive windage adjustment. The Gen 2 version is reduced in size and offers greater optics compatibility, with a spring-locking front sight post.

The sight is listed as fitting the AR-15 and installs on a Picatinny rail mount.
