Great things come in small polymer packages. The Magpul MBUS® 3 Rear Sight brings professional-grade tool-less adjustment and aperture flexibility to a backup sight that’s ready when your primary optic isn’t. By streamlining the original MBUS design to a compact 1.38” width, Magpul has created a snag-free, lightweight solution optimized for modern high-performance rifles.
Key Features & Tactical Benefits:
- 🚀 Rapid Ambidextrous Deployment: Features a spring-loaded, push-button mechanism for near-instant deployment. The ambidextrous button ensures quick access from any shooting position or setup.
- ⚙️ Tool-less Windage Adjustment: No more fumbling for tools or bullet tips in the field. The integrated windage dial allows for precise, on-the-fly corrections, mirroring the refined ergonomics of the MBUS Pro series.
- 🎯 Rapid-Select Aperture System: Switch between a wide aperture for close-range/low-light situations and a narrow aperture for long-range precision in seconds. The rotating window keeps your sight picture clear and adaptable.
- ⚖️ Lightweight Resilience: Weighing just 1.06 oz, the impact-resistant polymer construction provides incredible durability without adding unnecessary bulk to your build.
- 📐 Snag-Free Profile: Measuring only 0.55” tall when stowed, the MBUS 3 Rear stays completely out of sight until needed, ensuring maximum compatibility with magnified optics and various rail mounts.
