Magpul MBUS Gen 2 Rear Flip-Up Sight – Picatinny Rail (FDE)

The Magpul MBUS Gen 2 Rear Flip-Up Sight provides a low-profile backup aiming solution for AR-15s and other rifles with Picatinny rail systems. This polymer sight features spring-loaded flip-up deployment with dual apertures — a large peep for close-quarters shooting and a small peep for precision at distance. The ambidextrous push-button deployment allows for quick activation from either side of the rifle.

Constructed from impact-resistant polymer, the MBUS Gen 2 is lightweight and durable enough for field use. The sight locks securely in both up and down positions and sits low enough to coexist with most optic mounts. Installation requires no gunsmithing — the sight clamps directly to any MIL-STD-1913 Picatinny rail using a standard flathead screwdriver. Finished in Flat Dark Earth for desert and multi-cam environments.
