Product Description
The Magpul Industries MAG276-BLK MBUS Pro Back-Up Sight provides a compact, corrosion-resistant steel aiming solution for demanding 1913 Picatinny rail applications. Its low-profile design minimizes bulk while maintaining standard AR sight height when deployed, including on rail-height gas blocks.
Dual apertures and tool-free adjustments support practical field setup. The narrow front profile preserves clearance for many infrared aiming laser and light installations, while positive detents secure both sights in position.
- All-steel construction, case hardened and finished with Melonite QPQ.
- Rear sight features dual apertures and tool-free windage adjustment.
- Front sight offers no-tool elevation adjustment.
Built for reliable backup sighting.
