Magpul MBUS PRO Front Sight (MAG2275)

Magpul

The MBUS PRO 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 deep the MBUS PRO Front at standard AR sight height when deployed, and so low when they are stowed that you'll never notice them until they're needed. The narrow width front is compatible with most IR aiming laser and light installations for the professional user.
