The MBUS (Magpul Back-Up Sight) is a color injection molded, spring-loaded flip up sight that is easily activated from either side or by pressing the top. Detent and spring pressure keep the sight erect, but allows for unobstructed folding under impact. The detent knob easily and positively adjusts windage. The MBUS' impact-resistant polymer construction is lightweight and resists operational abuse. Protective wings shield the dual, same plan flip apertures. This sight is still able to be folded with either the large or small aperture in position. Fits most 1913 Picatinny rail equipped weapons, but is specifically tailored to the AR15/M16 platform. Stealth Gray finish. Made in the USA.
Weight with hardware: 1.3 oz. Height above rail, stowed: ~0.51". Center of aperture to top of rail: 1.42". Length, stowed: 2.6". Length, deployed: 1.5".
