Building on the success of the MBUS polymer sights, Magpul introduced the MBUS Pro. This flip-up rear sight has many of the same benefits of the original MBUS, but the MBUS Pro is constructed from steel and folds much flatter. This Magpul rear sight features a finger adjustable windage knob and slim, low profile design.

The Magpul MBUS Pro is a corrosion-resistant, all-steel backup 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 Picatinny rail mounting applications, including rail-height gas blocks.

Positive detents keep the MBUS Pro rear sight at standard AR sight height when deployed, staying so low when stowed that you'll never notice it until it's needed. The narrow width front is compatible with most IR aiming laser and light installations for the more professional user.
