From the manufacturer

Magpul MBUS Sights

The MBUS (Magpul Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. It is constructed of tough, impact resistant polymer to provide light weight and resistance to operational use.

The spring-loaded flip-up sight is easily activated from either side or by pressing the top. The spring pressure and detent keeps the sight erect and in position when deployed.

The detent knob on the rear sight easily and positively adjusts windage, and the front sight includes an elevation adjustment tool. However, most aftermarket A2 front sight adjustment tools may be used as well.

Clamps to most any MIL-STD-1913 Picatinny/STANAG 4694 railed hand guard and provides the same height-over-bore as standard A2 irons. NOTE: Cannot be mounted to a railed gas block due to excess heat issues.
