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 0.44” high when folded and 1.15” at its widest point. Its 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. The MBUS 3 sits at standard AR-height when deployed.
The MBUS 3 Front Sight includes tool-less elevation adjustments and a dual width enhanced front sight similar to the MBUS Pro.
The approximate size of the packed product or the sales package is 180 x 120 x 50 mm.

I would buy the more expensive equivalents next. However, it serves its purpose as a backup sight.

So, in the rush at 100 meters, you had to screw the spike as high as possible. You couldn't get any more hits lower...

Excellent scope. Even works well with a scope.

Good basic 'irons' - also works well with the red dot as a co-witness 👍

After a few weeks of experimentation, a few comments:
- The adjustable front grain is a really good addition
- Design better than Gen 2
- Easy to adjust
Definitely the best "back up" scopes on the market for the price.

The height adjustment is unnecessarily rigid for the grain. Not good.

Too low to put on the gas port, the adjustment margin runs out. Otherwise, it seems quite competent, e.g. the rail on top of the hand guard is probably ok.
