Mbus pro sights - Magpul Industries MBUS Pro Flip Up Sights

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
