Magpul MBUS 3 Back-Up Front Sight - Black

The Magpul MBUS 3 Back-Up Front Sight brings professional-grade functionality to a lightweight, polymer design. Building on the legacy of the MBUS Pro, this sight features tool-less elevation adjustment for quick zeroing without tools.

Designed for ambidextrous operation, the push-button deployment mechanism allows rapid flip-up or flip-down activation from either side of the firearm. The sight mounts securely to any Mil-Spec M1913 Picatinny rail.

Constructed from durable polymer, the MBUS 3 weighs only 0.0925 lb, making it an ideal backup sight for AR-15, M4, M16, AR-10, and compatible platforms without adding unnecessary weight to your setup.
