The MAGPUL MBUS Pro LR Rear Sight (MAG527-BLK) 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 Melonite™ finished steel, 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 they're stowed that you will hardly notice them.
