Magpul MBUS Pro Front Sight (AR-15)

The MBUS (Magpul Back-Up Sight) 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 dual aperture, windage adjustable rear and no-tool, elevation adjustable front excel in all 1913 Picatinny rail mounting applications, including rail-height gas blocks. Positive detents keep the MBUS Pro Front and Rear 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 steel, rectangular front sight post is selectable between Match and Standard widths:

• .04” Match width for increased precision
• .06” Standard width for maximum visibility
