Magpul Mbus Frnt Flip Sght Gen 2 Gry

The Magpul MBUS Front Flip Sight Generation 2 in Grey is a lightweight, spring-loaded backup front sight designed for AR15 and M16 platform rifles with Picatinny-railed handguards. This polymer construction sight delivers practical functionality at a proven price point, offering operators a reliable secondary aiming solution that deploys instantly when primary optics fail or require redundancy during field operations.

The Gen 2 design features elevation adjustments to dial zero at your intended distance, with protective wings that shield the A2-style front sight post and its spring-lock mechanism. Activation is intuitive—press the top or flip from either side to bring the sight into battery. The compact 4.25-inch profile and minimal 0.13-pound weight integrate seamlessly into modern tactical setups without adding notable bulk or requiring dedicated mounting real estate beyond your existing rail system. Polymer construction resists corrosion in variable environments while maintaining structural integrity across thousands of deployment cycles.

This sight suits shooters, law enforcement, and military users who run primary optics but maintain iron sight backup capability. Patrol officers relying on carbines, precision rifle teams conducting transition drills, and trainers building fundamentals-focused curricula consistently choose MBUS sights for their simplicity, zero maintenance overhead, and proven reliability. The flip-up design collapses flat when not in use, clearing your line of sight to a mounted red dot, scope, or magnified optic without obstruction.

Magpul MBUS sights remain the industry standard for affordable, field-proven backup iron sights on AR platforms. The Gen 2 refinement builds on years of proven performance, delivering dependable zero hold and manipulation durability that matches or exceeds sights at multiple times the cost.
