Description
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

    Great rear back up sight. All steel construction

    Posted by 2A Michael J on 17th Jan 2022

    I've purchased these before, utilized some different brands, and I keep coming back to these sights. Really phenomenal. Tactile clicks, all steel construction, backed and made by Magpul. You really can't ask for more. I highly recommend them and Arms Unlimited sells them for a really fair price. The only con I can think of is the rear aperture is only protected when flipped up to smallest hole. It is all steel so the likelihood they would break is still very low. I've known ARMY brothers who've used these in combat zones without breakage.

    Absolutely the best price anywhere when I purchased. Shipping speed was decent but not extraordinary. Would’ve waited twice that for what I paid, gladly.

    Sturdy and low profile

    Posted by Andrew P on 2nd Dec 2021

    Got these on sale along with the matching front sight. They are sturdy and low profile when folded out of the way and are sufficient for use as iron sights in lieu of an optic.
