The Magpul MBUS 3 is the next evolution in back-up sight systems, combining the best attributes of its predecessors—the original MBUS and the MBUS Pro. This advancement embodies a blend of functionality, robustness, and value that sets a new standard for auxiliary firearm sights.
Reduced to an impressively compact form factor, the MBUS 3 measures just 0.44 inches high when folded and reaches only 1.15 inches at its widest point. Its design draws inspiration from the sleek aesthetics of the MBUS Pro while employing impact-resistant polymer construction. This choice of material ensures that it remains lightweight yet remarkably durable under demanding conditions.
True to Magpul's commitment to innovation, this sight features spring-loaded technology inherited from earlier models. It allows quick deployment with an ambidextrous push-button mechanism—ensuring readiness when seconds count.
When deployed, the MBUS 3 Rear Sight aligns perfectly with standard AR-height configurations and includes a rapid-select aperture system for versatile targeting options. Whether you are on patrol or at practice on your local range, these sights offer reliability you can trust without unnecessary bulk or weight.
