Frequently Asked Questions
What is the difference between the Magpul MBUS Gen 1 and Gen 2 rear sights?
The Gen 2 MBUS Rear Sight features an updated, lower-profile design with improved protective wings that better shield the apertures. The spring-loading mechanism was also refined for faster, more reliable deployment compared to the original Gen 1 model. The Gen 2 is the current production version and the one recommended for most builds.
Can I pair this MBUS Rear Sight with a magnified optic or red dot sight?
Absolutely. The MBUS Gen 2 Rear Sight is specifically designed to function as a co-witness or offset backup when used alongside red dot sights, holographic sights, or magnified optics. When not needed, it folds flat to remain completely out of your optic's field of view, making it an excellent companion to any primary sighting system.
Do I need a front sight to use the MBUS Gen 2 Rear Sight?
Yes — to form a complete iron sight system, you'll need a compatible front sight such as the Magpul MBUS Gen 2 Front Sight. The rear sight alone establishes your point of aim for windage, but a matched front sight is required for a full, usable sight picture. Magpul offers the front and rear sights both individually and as a set.
