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

    I got these at a steal, almost half off the price of the front and rear sight , both sides are top quality and are good for precision shooting with iron sights, I should know because I qualified Expert with iron sites in the Marine Corps

    Great product and price

    Posted by John Dorian on 25th Feb 2022

    (leaving same review for the front sight) Recently purchased fold-up Magpul front and rear sights as backups for my AR-15. Both products were shipped quickly and arrived safely. They’re great! I know people like the regular MBUS too…but I hate the idea of plastic sights on an AR. If you’re on the fence, just do it! They fold up/down just fine, and don’t interfere with my red dot at all. Great back up sights!

    Wow!!

    Posted by Monty Koch on 1st Feb 2022

    To be honest, I was skeptical. Shopping for back up iron sights and I could not believe the price. I decided to roll the dice and I am glad I did. My order arrived in just a few days and in perfect condition. I am a customer for life now. Thanks Arms Unlimited!

    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.
