Features

  • The next evolution in our MBUS (Magpul Back-Up Sight) line, the MBUS 3 incorporates the best features, strengths and value of our original MBUS and MBUS Pro Sights in a feature-packed back-up sight system
  • Significantly reduced in size from the MBUS, it sits at just 0.47 high when folded, 1.38 at its widest point, and weighs a scant 25 grams with hardware
  • Aesthetics are derived from the MBUS Pro, but the MBUS 3 Front Sight is constructed of our impact-resistant polymer, making it lightweight and extremely durable
  • Featuring the same spring-loaded technology as its predecessor, they can be deployed with an ambidextrous push-button
  • Sits at standard height when deployed and includes tool-less elevation adjustment of a dual width enhanced front post similar to the MBUS Pro

    • The standard in backup sights
Color: Black Style: Back Sight
It's a Magpul MBUS - what else is there to say. The standard in backup sights. Third generation is the latest and best of the MBUS backup sights. Polymer, but decent quality. More convenient to operate than the Pro aluminum version.

    • Magpul 100% quality
Color: Flat Dark Earth Style: Front Sight
This is my 11th set of Magpul MBUS 3 sights, and with Magpul, these are always 100% quality. Regardless of what MCOG you are running, you will always need a quality backup, and the Magpul MBUS 3 is the best there us.

    • Top quality at a great price
Color: Flat Dark Earth Style: Back Sight
These are Magpul and just like other products they make, these are top quality sights. They come in black or dark flat earth colors depending on what you prefer on your setup. The sights are fully adjustable for wind and elevation and are co-witness with scopes or red dots. Mounting was super simple, just need a flathead or phillips screwdriver to loosen and tighten the piece that goes on the picatinny rail. All plastic but very durable. They hold zero after 3000 rounds so far and seem to be able to handle much more. Great replacement for iron sights or in case of emergency while out in the field. Magpul all the way!! ... show more

    • Notice how they don't specify color.
Color: Olive Drab Green Style: Front Sight
The listing failed to specify that the sight is OD Green. Other than that, it is Magpul, you know what you're getting.

    • I mean it's Magpul so...
Color: Black Style: Back Sight
Really like how compact the gen 3 is. I have a 3x magnifier and wanted to keep some backup sights that could be mounted as far back to the rear as possible and this sight works perfectly. Same great quality that magpul is known for, they work great.

    • Magpul quality
Color: Black Style: Back Sight
Really nice backup for my STAG-1 AR in case the red dot goes out. Lines up with the front triangle post sight for co-witness through the red dot when needed. Spring loaded pop-up is a nice feature as well. Two apertures just like a carry handle sight, one for close work and one for precision.
