A front impact should be no problem for a sight such as the MBUS Pro, as it is non locking, but I would be concerned about a side impact, such as it appears markm's DD sight had. I would assume Magpul would have done all kinds of drop tests, including side impact, before product release. I'd be interested to know/see the results.
Maybe someone will eventually make a well designed titanium one or a plastic one that has hardened steel protective ears molded into it along with threaded inserts for the sight post and clamping bar.

Not sure if Ti is the answer, though I'll admit that I have very little working knowledge of it. What I do know is that it has incredible weight-to-strength ratios. Not sure if that really speaks to it's resistance to impact.
Hard steel resists bending, but will break when force is greater than it's strength. Polymer, like the MBUS, has the ability to deflect and return to it's original form until the force is greater than it's maximum deflection range, and then it breaks as well.
I still believe Magpul rules in overall durability in both it's steel non-locking design and the locking polymer original designs. Maybe they should consider a blended polymer/steel design that would incorporate the non-locking steel base with the excellent deflection rebounding polymer upper piece. Although, another great advantage of the Pro model is the thin folding sight base, and I'm not sure they could get the strength of the Pro sight by making the polymer that thin. The Pro sits very low when not in use.
Just my thoughts based on what I remember from incomplete mechanical engineering studies several years ago.
A true side impact would not hit the irons at all. At the angle the rifle likely hit, based on how the sight bent, would still cause the Pro to fold. It would still likely cause some damage to the sight but would still be usable, unlike the DD pictured above.
DD makes a great product but I don't think their design intent is based on dropping a 7 or 8 lbs rifle on it. That's one area I think Magpul put some thought into. Maybe not to survive unscathed, but certainly remain serviceable until the battle is won and the sight can be replaced.
Hell no. But what's the alternative?
I have whacked the living shit out of my rail mounted lights... much harder than the fall this gun took, and the rail didn't break. I've never even heard of a rail breaking short of an IED or vehicle roll over.
