Magpul MBUS 3 Front Sight - Black

Magpul MBUS 3 Front Sight – Black

MAG1166-BLK -MBUS Value Meets MBUS Pro Features

The next evolution in our MBUS (Magpul Back-Up Sight) line, the MBUS 3 incorporates the best features, strengths, and value of our original MBUS and MBUS Pro Sights in a feature-packed back-up sight system.

Significantly reduced in size from the MBUS, it sits at just 0.47” high when folded, 1.38” at its widest point, and weighs a scant 25 grams with hardware. Its aesthetics are derived from the MBUS Pro, but the MBUS 3 Front Sight is constructed of our impact-resistant polymer, making it lightweight and extremely durable. They have the same spring-loaded technology as its predecessor so that they can be deployed with an ambidextrous push-button.

WHEN DEPLOYED, the MBUS 3 Front Sight sits at standard AR-height and includes tool-less elevation adjustment of a dual width enhanced front post similar to the MBUS Pro.

*NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed forend on the same plane as the receiver rail. Because of this, the sight is also not compatible with MOE Hand Guards.
