- 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
- 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
- Featuring the same spring-loaded technology as its predecessor, they can be deployed with an ambidextrous push-button
- Sits at standard height when deployed and includes tool-less elevation adjustment of a dual width enhanced front post similar to the MBUS Pro
