Magpul MAG527-BLK MBUS Pro LR Adjustable Sight Rear Black Adjustable for AR-15

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. With its all steel case hardened and finished with Melonite for extreme resistance to wear and corrosion, this is the sighting solution that delivers no-tool adjustments, maximum strength, corrosion resistance, and functionality in a compact package. Elevation adjustment wheel is set for 200-600 M distances with 50 M increment adjustments. 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. Small aperture diameter 0.07 in. Large aperture diameter 0.19 in. Made in the USA.
