The most fragile sighting system you can have are front and rear BUIS as your primary in the flipped up position. One good drop on concrete and those things are DONE at the least your zero is off. Strangely enough, people who shit on the plastic MBUS, those things survive better than any of the metal ones FYI. Anything that locks upwards is automatically ****ed in a drop. Which is why I will NEVER run Troys on any of my rifles ever again.
