Magpul MBUS 3 Front Sight – MAG1166-BLK, Black, Flip-Up
The Magpul MBUS 3 Front Sight (MAG1166-BLK) is a next-generation backup sight that merges the lightweight, value-driven design of the original MBUS with the professional-grade features of the MBUS Pro series. Engineered for modern sporting rifles, it’s crafted from impact-resistant polymer, spring-loaded for instant deployment, and significantly reduced in size for maximum versatility.
This advanced front sight clamps securely to any MIL-STD-1913 Picatinny rail and deploys to standard AR height at the push of an ambidextrous button. Offering tool-less elevation adjustment, the MBUS 3 features a dual-width enhanced front post for rapid, precise aiming. At just 0.47” high when folded and weighing only about 25g, it delivers robust performance while taking up minimal rail space—ideal for rifles with magnifiers, lasers, or optics.
