Magpul MBUS Pro LR Rear Sight (MAG527)

The new MBUS Pro LR capitalizes on the low profile and sleek styling of the original MBUS Pro, while adding the additional feature of an elevation adjustment wheel 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.
