The next evolution in the Magpul Flip-Up Front Sight MBUS line, the MBUS 3 incorporates the best features, strengths and value of the 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 0.44" high when folded and 1.15" at its widest point. Its aesthetics are derived from the MBUS Pro, but the MBUS 3 Front Sight is constructed of 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. The MBUS 3 sits at standard AR-height when deployed. The MBUS 3 Sight includes tool-less adjustments and a dual width enhanced sight similar to the MBUS Pro.ELEVATION ADJUSTMENT1.6 MOA (1.886"/100m) per click with a 14.5" sight radius1.2 MOA (1.367"/100m) per click with a 20" sight radiusWINDAGE ADJUSTMENT0.7 MOA (0.754"/100m) per click with a 14.5&quo...
