Magpul MBUS Back-Up Flip Sight - Rear

The Magpul MBUS Back-Up Flip Sight - Rear is the first of its kind: a sight designed as a low cost, color injection molded polymer, folding back up iron sight. The MBUS (Magpul Back Up Sight) fits all Picatinny rail equipped weapons, but is specifically tailored to the AR15/M16/M4 platform. Dual aperature, adjustable for windage.

Rear MBUS - The rear MBUS has a windage adjustment knob on the right side that adjusts the POI approximately 3/4" at 100 meters for each click. Both large and small apertures are provided; the small aperture flips forward out of the way, rather than rearward, and can be left down when stowing the sight. Available in Black, or Tan.
