Magpul MBUS Back Up Folding Sight - REAR - Black



Fits same 1913 picatinny rails.

The MBUS (Magpul Back-Up Sight) 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.

FEATURES:
  • 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.
  • Clamps to MIL-STD-1913 Picatinny/STANAG 4694 receiver rail and provides the same height-over-bore as standard A2 irons.
  • 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.
