Magpul MBUS Back-Up Sights - Black

MorBius
The MBUS (Magpul Back up Sight) is a low cost, color injection molded polymer, folding back up iron sight available in (3) colors – Black, Dark Earth, and Foliage Green. The MBUS fits all Picatinny rail equipped weapons, but is specifically tailored to the AR15/M16/M4 platform. The front sight 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 (Point of Impact) is moved approximately 1-7/8" at 100 meters, based on a 14.5" M4 sight radius. The rear sight 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. #arms #Magpul #rifle #rifle_sight #sight #weapon
