The Magpul MBUS Front Sight is a rugged, lightweight backup sight designed for the AR-15 and M16 platform. Whether you're running a dedicated optic setup or stacking iron sights as a backup, this folding sight gives you a compact solution that stays out of the way until you need it. Built from impact-resistant polymer, it weighs next to nothing and won't slow you down—yet it's tough enough to handle the recoil and handling abuse that comes with real-world shooting and training.
The MBUS front sight mounts directly to any MIL-STD-1913 Picatinny rail on your handguard, and it's precisely calibrated to match the height-over-bore of standard A2 irons, so your zero translates seamlessly between backup and primary sights. The spring-loaded flip mechanism deploys and locks with equal ease from either side or a quick press on top—no fumbling in a stress situation. When you fold it away, the detent and spring pressure keep it rock-solid until impact forces it down; protective wings shield the front post and spring assembly from damage.
Elevation adjustment is intuitive: the included tool handles it, but most aftermarket A2 sight tools work too. This is the kind of no-frills, purpose-built gear that earns its place on a working rifle. Made in the USA, the Stealth Gray finish blends into modern furniture while the sight itself blends into your workflow.
