The Magpul MBUS Pro Offset Rear Sight (brand part no. MAG526-BLK) is a Melonited-steel backup iron sight built to mount on an M1913 Picatinny rail at a 45-degree offset from a rifle’s primary optic. Magpul Industries built on the proven MBUS Pro platform so that, if a magnified optic is ever damaged or a target appears too close for it, a shooter can simply rotate the rifle 45 degrees for an instant, fully-featured iron sighting solution. It pairs exclusively with the MBUS Pro Offset front sight (MAG525) to complete the system.
