The Magpul MBUS Back-Up Sight - Front 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.
The Magpul MBUS Back-Up Front Sight has two protective ears that are slanted inwards at the top, rather than outwards like the standard M16 front sight, providing a sight picture much like the original Troy sights with the rounded ears. The front uses a standard square front sight post, which can be adjusted with a 4-prong M16 sight adjustment tool. For each 1/4 rotation, the POI is moved approximately 1-7/8" at 100 meters, based on a 14.5" M4 sight radius. Once sighted in, the sight post can be prevented from rotating by installing a roll pin (two lengths are supplied) to lock it in place. Available in Black or Tan colors.
