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 0.55” high when folded 1.38” at its widest point and weighs a scant 30 grams with hardware. Its aesthetics are derived from the MBUS Pro but the MBUS 3 Rear 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.
The MBUS 3 Rear Sight sits at standard AR-height when deployed and includes a windage adjustable rapid-select aperture system.
Made in the USA.
