Magpul MBUS Gen 2 Rear Flip-Up Back-Up Sight - Black MAG248BLK

When your optic goes down, hesitation isn’t an option. The battery fails, the glass cracks, and in that instant between success and failure, only one thing matters—being ready. That’s the moment Magpul envisioned when they created the Magpul MBUS Gen 2 Rear Back-Up Sight. It’s not just a polymer sight—it’s a failsafe designed to keep you in the fight when your primary optic can’t.

Born from Magpul’s reputation for functional innovation and uncompromising dependability, the MBUS Gen 2 redefines what a back-up sight can be. Designed for shooters who demand absolute reliability, it delivers rugged performance without the added weight. Whether you’re a professional on duty, a competition shooter chasing every advantage, or a prepared citizen who trusts their rifle to protect what matters most, the MBUS Gen 2 ensures you’ll never be caught off guard.

Engineered for strength and speed, the MBUS Gen 2 deploys with a swift press from either side or the top—its powerful spring mechanism snapping the sight into action instantly. The design is ambidextrous, intuitive, and built for the moments when time is measured in heartbeats. Once deployed, it provides a consistent, standard A2 sight picture, giving you the confidence to acquire your target with precision and speed.

Magpul’s lightweight, impact-resistant polymer ensures the MBUS Gen 2 can take punishment without adding unnecessary weight to your rifle. It stays low and out of the way when folded, ready to rise when you need it. And with its dual same-plane apertures, you can switch between rapid target acquisition and precision shooting in seconds—all without tools. Every feature reflects Magpul’s dedication to simplicity, durability, and performance.
