Magpul Gen II MBUS Rear Back Up Sights

The new MBUS (Magpul Back–Up Sight) GEN 2 is a low–cost, color injection molded, folding back–up sight.

The dual aperture MBUS Rear Sight is adjustable for windage and fits most 1913 Picatinny rail equipped weapons, but is specifically tailored to the AR15/M16 platform.

Made in U.S.A.

  • Impact resistant polymer construction provides light weight and resists operational abuse
  • Spring–loaded flip up sight easily activated from either side or by pressing the top
  • Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.

  • Protective wings shield the dual flip apertures
  • Sight can still be folded with either large or small aperture in position
  • Detent knob easily and positively adjusts windage
