Magpul MBUS 3 Polymer Flip-Up Front Sight – Black AR-Height

The Magpul MBUS 3 Front Sight represents the evolution of Magpul’s back-up sight systems, integrating proven features from the original MBUS and MBUS Pro Sights into a compact, polymer-based solution. Engineered for durability and lightweight performance, this sight is constructed from an impact-resistant polymer.

Compact and Functional Design

• Significantly reduced footprint, measuring 0.44 inches high when folded and 1.15 inches at its widest point. This slim profile ensures minimal obstruction when used alongside primary tactical optics or other firearm accessories.
• Aesthetically aligned with the MBUS Pro, maintaining a professional appearance.
• Features a spring-loaded mechanism for rapid deployment. Activation is achieved via an ambidextrous push-button, allowing for quick transitions.

When deployed, the MBUS 3 Front Sight sits at standard AR-height, ensuring compatibility with common sighting systems. It incorporates tool-less elevation adjustments for efficient zeroing and features a dual-width enhanced front sight post, similar to the MBUS Pro. This sight provides a dependable backup solution for various applications, from dedicated range use as part of your shooting range equipment to serving as a reliable secondary sight on personal defense firearms.
