Magpul MBUS3 Flip-Up Sights The next evolution in our MBUS (Magpul Back-Up Sight) line, the Magpul MBUS3 Flip-Up Sights incorporate 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. Featuring the same spring-loaded technology as its predecessor, they can be deployed with an ambidextrous push-button. The Magpul MBUS3 Flip-Up Sights sits at standard AR-height when deployed and includes tool-less elevation adjustment of a dual width enhanced front post similar to the MBUS Pro. Made in the USA. Specifications Spring-loaded flip up sight easily activated from either side or by pressing the top Protective wings shield the dual, same plane flip apertures Sight can still be folded with either large or small aperture in position Detent knob easily and positively adjusts windage Polymer construction provides light weight and resists operational abuse Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc. Clamps to MIL-STD-1913 Picatinny/STANAG 4694 receiver rail and provides the same height-over-bore as standard A2 irons More Magpul Here
