Magpul MOE MBUS Back-Up Front Sight Black MAG275BLK

The Magpul MBUS Back‑Up Sight system is a no-nonsense, battle-ready solution for shooters who need reliable iron sights that won’t break the bank. Injection-molded from rugged polymer, the MBUS sights fold flush when not in use and pop up instantly when you need them, giving you a dependable back-up to electronic optics without adding unnecessary weight or bulk. Designed with practical use in mind, these sights are built to withstand hard handling, recoil, and the everyday abuse of range life or field work.
The MBUS Front Sight is adjustable for elevation and engineered to fit most 1913 Picatinny-railed handguards, with geometry tailored specifically to the AR-15/M16 platform. Its positive detent locking keeps the sight rock-solid when deployed, and the low-profile folded position stays out of the way of optics, lasers, and other rail-mounted gear. The sight’s intuitive controls let you make quick adjustments with common tools or even gloved hands, so you can zero and maintain alignment without fuss.
Color-injection molding gives these sights a uniform finish and excellent impact resistance while keeping manufacturing tolerances tight. The result is a sight that feels solid under hand and won’t chip or peel like painted parts. Installation is straightforward—mount to any standard Picatinny rail, verify alignment, and you’re ready to go. When paired with Magpul’s rear sight or other quality rear irons, the MBUS front sight provides a straightforward, repeatable sight picture that keeps you on target if your primary optic fails.
Magpul designed MBUS for practicality: lightweight, corrosion-resistant, and low maintenance. The sights resist solvents, moisture, and temperature extremes, so they won’t swell, rust, or lose function in adverse conditions. Their compact footprint and positive indexing make them a favorite for duty rigs, trail rifles, and range builds where backup capability is non-negotiable. Whether you’re fielding a patrol rifle, outfitting a patrol carbine, or assembling an affordable training setup, MBUS gives you proven function with minimal compromise.
For shooters who value durability, simplicity, and sensible pricing, the Magpul MBUS Front Sight is a reliable insurance policy for your sighting system—effective, unobtrusive, and built to last.
