Magpul MBUS Pro Front Sight Flip-Up Back-Up Sight

The MBUS Pro (Magpul® Back-Up Sight) is a corrosion-resistant all-steel back-up sighting solution that delivers maximum functionality and strength with minimum bulk at a price that's even smaller than its size.

The no-tool, elevation adjustable front sight excels in all 1913 Picatinny rail mounting applications, including rail-height gas blocks. Positive detents keep the MBUS Pro at standard AR sight height when deployed, and so low when they are stowed that you'll never notice it until it's needed. The narrow width is compatible with most IR aiming laser and light installations for the professional user.
