Magpul MBUS Folding Rear Sight for Picatinny Rail (Black)
Magpul MBUS (Magpul® Back-Up Sight) is a reliable and lightweight system of open folding sights (rear and front sights) for mounting on the unified Picatinny MIL-STD-1913/STANAG 4694 profile. The design is made of impact-resistant polymer, which provides an optimal combination of low weight and high strength. Thanks to this material, the sights withstand intensive use and maintain the geometry of the aiming line.
The quick-deployment mechanism works simply and intuitively: by pressing the button on top, the rear sight flips up under spring action and locks in the vertical position. For folding, a simple press is enough, which makes the device convenient in field conditions, when shooting from cover, or during transportation. The height of the rear sight above the barrel corresponds to the AR-15 A2 standard: the distance from the center of the aperture to the top of the rail is 1.42” (36 mm), which allows the use of standard aiming procedures and compatible sights.
The kit includes an adjustment tool, which allows precise customization of the sight to the individual needs of the shooter. The dimensions and geometry of the MBUS are designed with compatibility in mind for typical carbines and pistols in modern designs.
