Magpul MBUS 3 Rear Sight
The Magpul MBUS 3 Rear Sight features an impact-resistant polymer construction that keeps weight low while maintaining durability for field use. Its ambidextrous, spring-loaded push-button deployment allows rapid activation, and when folded it maintains an ultra-low profile to minimize snagging. When deployed, it aligns to standard AR sight height for compatibility with most front sights and optics. The dual-aperture rear sight system provides quick transitions between close-range and precision sighting, and windage adjustment is tool-less for fast zeroing. Designed for rifles using MIL-STD-1913 rails, the MBUS 3 Rear Sight integrates seamlessly into AR-10, AR-15, M4, M16, M110, SR-25 and similar platforms.
