Magpul | MBUS Pro LR Rear Sight | Black

The MBUS Pro LR rear sight (MAG527) is Magpul's all‑steel MBUS Pro rear with an elevation wheel for 200 to 600 meters in 50‑meter clicks. You still get the dual aperture (small for precision, large for close or low light), tool‑less windage, and a Melonite / QPQ finish on case‑hardened steel. Magpul calibrated the wheel as a hybrid for common 5.56 and 7.62 loads rather than a single dope card, so treat it as a working approximation, not a sniper's click chart. Positive detents hold it up or folded. Made in the USA.
