Quality and Precision

by Kahuna, from United States, CA Written on December 8, 2014
I purchase the Magpul MBUS as I just completed an AR build in Flat Dark Earth and this and the Front Flip-Up Back Up sight. The install was easy as well as to "zero" them in. I have a number of Magpul items and these sights are reasonably priced. I recommend Magpul products to keep your carry rifle on the lighter side....

  • quality product for a fair pric

Great buis

by Mr52, from United States, OH Written on October 24, 2014
Nice sight very nice to fold down out of the way while using red dot or other optics. Not the easiest or in general the most adjustable but it will get the job done if you need iron sights. I now wish I could add the front version as well but that will have to wait for a little gunsmith in....

Works Great!

by Nickname, from United States, CA Written on October 6, 2014
Sight works great as a back up or primary one. Installed it on my AR-10 and worked perfectly after it's first day at the range. Love the way it flips up for fast use when needed but lays flat against the rail for mobility when using my scope. Multiple apertures allow for distance as well as close range shooting. Always excellent service from Opticsplanet....

Performs exactly as expected. Although polymer in design, it has a very robust and durable feel to it. Would and have recommended to friends. Typically I am pleased with Magpul designs and products....

Great finish to a FDE build!

by JJ, from United States, TN Written on September 5, 2014
I bought both a rear and front sight. Magpul quality you can count on. They won't let you down when you need them. Beware of EBAY fakes, buy from a reputable dealer like Optics Planet! Optics Planet has fast shipping too, big plus....

Great sights for the not rich

by Mike, from United States, TX Written on August 7, 2014
These are very nice for the money and work great. Nice tight fit and solid feel. They open with a very good snap. I bought front and rear; they make a nice sight picture. Co-witness with my Lucid HD7 just fine but I keep them folded down out of the way....

Quality Sight-Economic Price

by hondaracer173, from United States, NC Written on July 31, 2014
Great sight, especially for the money. Tight fit on picatinny rail, sight in was a breeze, love the push-button flip up activation. I used these sights for transition sights on a 45 degree angle mount, I can be looking down the sight of my red dot and flip these sights up without moving my head or changing how I'm holding my AR just by pushing the button. Will buy again for another AR build....
Pros:
  • GREAT PRICE
  • great quality
Cons:
  • None
