The Magpul MBUS Pro LR Sight Set combines the rugged, all steel MBUS Pro front and MBUS Pro LR rear sights in a package that provides a cost savings. The MBUS Pro LR capitalizes on the low profile and sleek styling of the original MBUS Pro, while adding the additional feature of elevation adjustments to accurately engage targets at variable distances. Built with all steel construction, this is the sighting solution that delivers no-tool adjustments, maximum strength, corrosion resistance, and functionality in a compact package. Positive detents keep the MBUS Pro LR at standard AR sight height when deployed and so low when stowed that you will hardly notice them. The MBUS Pro fr Mfg: Magpul
