Magpul MBUS Pro LR Rear Sight - Black

Magpul continues to grow and develop based on innovation, simplicity, and efficiency. At Magpul, mission driven requirements inform their product design, materials, and manufacturing, focusing on efficiency without sacrificing quality or performance. The MBUS Pro LR is a case hardened steel back-up sighting solution protected by a Melonite finish for excellent corrosion resistance. With low-profile, sleek styling, the MBUS PRO LR adds an elevation adjustment wheel to accurately engage targets at variable distances. The MBUS Pro LR features tool-less elevation and windage adjustments. Positive detents keep the MBUS Pro LR locked into place while stowed or deployed.
