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. A must for dead-on accuracy!
- Impact-resistant polymer construction resists operational abuse
- Spring-loaded flip up sight is easily activated from either side or by pressing the top
- Spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.
- Clamps to MIL-STD-1913 Picatinny/STANAG 4694 receiver rail
- Provides the same height-over-bore as standard A2 iron sights
- Protective wings shield the dual, same plane flip apertures
- Sight can still be folded with either large or small aperture in position
- Knob easily and positively adjusts windage
