The MBUS Pro (Magpul Back-Up Sight) is a corrosion resistant all-steel back-up sighting solution that delivers maximum functionality and strength with minimum bulk at a price that's even smaller than its size.

The dual aperture, windage adjustable Rear and no-tool, elevation adjustable Front excel in all 1913 Picatinny rail mounting applications, including rail-height gas blocks. Positive detents keep the MBUS Pro Front and Rear at standard AR sight height when deployed, and so low when they are stowed that you'll never notice them until they're needed. Narrow width Front is compatible with most IR aiming laser and light installations for the professional user.

Made in U.S.A.

Features:

  • All steel construction
  • Case hardened and finished with Melonite QPQ&trade for extreme resistance to wear and corrosion
  • Mounts on any MIL-STD-1913 Picatinny/STANAG 4694 rail
  • Windage adjustable with low-profile knob – no tools required
  • Positive detents in both the up and down positions
  • Standard AR sight height when deployed

Specifications:

  • Weight, w/ hardware: 1.80 oz.
  • Height above rail, stowed, at mid-point: ~0.37"
  • Length, stowed: 2.1"
  • Aperture height over rail: 1.41"
  • Small aperture dia.: 0.07"
  • Large aperture dia.: 0.19"

Windage Adjustment:

~0.5 MOA (0.566"/100m) per click with a 14.5" sight radius
~0.4 MOA (0.410"/100m) per click with a 20" sight radius

    Nice

    Low profile, well made and nice positive engagement. Knob is very stiff to turn but hopefully after it is used for awhile it will be a bit easier to turn. You don't want it loose but this certainly requires enough effort that you have to change your grip. very pleased overall.
