The Magpul MBUS Pro is a case hardened steel back-up sighting solution protected by a Melonite finish for excellent corrosion resistance. The dual aperture MBUS Pro Rear Sight features tool-less windage adjustments. Positive detents keep the MBUS Pro Rear locked into place while stowed or deployed. Designed for AR-platform rifles, the MAG276-BLK mounts securely to any Picatinny rail and stays out of the way when not needed.
The MBUS Pro Rear Sight delivers approximately 0.5 MOA per click with a 14.5″ sight radius, or 0.4 MOA per click with a 20″ sight radius. When stowed, the sight stands just 0.37″ tall and 2.1″ in length, rising to standard AR sight height (1.41″ above the rail) when deployed. The small aperture measures 0.07″ in diameter while the large aperture is 0.19″ in diameter, and the sight weighs only 1.80 oz. This minimal profile makes it ideal for co-witnessing with optics or standalone use on any modern tactical rifle.
Low profile and snag free, the MBUS Pro rear sight combines proven reliability with no-compromise durability. Every component is engineered for field performance—from the rugged all-steel construction to the intuitive windage knob that requires no tools for adjustment. Whether you’re building a duty-grade AR or adding a dependable backup to an optic-equipped setup, the Magpul MBUS Pro delivers the precision and ruggedness that professionals demand.
