Magpul’s flip up front and rear sights are very popular for their high quality and budget price, Magpul recently released their second generation MBUS sights. The redesigned MBUS Gen 2 is compatible with all Milspec 1913 Picatinny rails and features a slimmer profile over the first gen MBUS to provide better optics compatibility. The front sight has a positive detent to securely lock the front sight post in place while the rear also features plane small, large and the NAWS (No Aperature Window Sight) apertures. Made out of reinforced polymer the MBUS Gen 2 is lightweight and durable and is sure to be a must have for your next AR build.
