Most Helpful Positive Review Mbus pro flip sights
Low profile, a lot smaller than the plastic mbus. Does not have button for engaging sight but flips up manually fairly easy. Positive clicks for elevation and windage. No need for any tools to adjust. Was worried about losing zero by acidently hitting, but after handling there is no chance of that ...

Most Helpful Negative Review turn knobs questionable
you can tell, just by looks, these are TOP quality sights, however.... I am still having a problem adjusting (turning) knobs. I don’t want to use pliers to loosen them... but I may have no choice. for this fault I cannot give a high rating. if I get them loose I will re-rate.

Mbus pro sights

by Ryan, Verified Owner from MN, United States Written on March 20, 2026
Sight quality seems extremely good. Very sturdy feeling with very positive engagement and nice snap in up and down position. A little stiff but might break in a little. Doesn’t pop up like the plastic sights but I bet these could take a serious beating and still keep on trucking. The one thing that annoys me is the “thread locker” they used is some crumbly tan garbage. I’ll probably just add a drop of blue locktite and move on with my life

Great sights (not much else to say)

by CB1004, Verified Owner from FL, United States Written on February 22, 2026
These are great backup sights. In fact, I threw these on my 9mm CMMG Dissent and I did NOT need to adjust anything. They were right on target.

My ONLY complaint would be that these are manually deployed. I have a set of the MBUS on a different weapon and those have the quick deploy button.

MBUS PRO Rear

by kurt, Verified Owner from NJ, United States Written on February 19, 2026
Paired this up with a standard A2 FSB, and I have to say the MBUS Pro is much slimmer than I imagined. It as well looks better that in the photos. After its initial installation, the first flip open was very stiff. I put just a tiny bit of slip 2000 on the pivot mechanism and it now glides smoothly, while still maintaining an incredibly positive click into and out of flipping the sight. This is my first non polymer rear sight and I highly recommend, it fits the quality of the FSB nicely.
Pros:
  • Well constructed
Cons:
  • None

Magpul MBUS Pro LR

by Jim, from TX, United States Written on September 16, 2025
These have a very small footprint and are very well made. They don't lock open but unless you have a hard recoiling rifle, that shouldn't be a problem as the detent is stout. The adjustments are precise and tool less. Honestly the best BUIS I've ever used.

Almost perfect.

by Street sweeper, Verified Owner from GA, United States Written on September 21, 2024
I spent many hours looking on the internet and asking around before i made this purchase. These are some of the slimmest sights while also being feature rich and aesthetically pleasing. My only complaints are that they are in meters and don't lock in the open position. A spring assist would be helpful too.
