The reliability of the VZ 58 in the field is legendary... on an anecdotal basis. However, there are plenty of videos of M4 environmental torture tests, but I could only find one lame one of the VZ 58 where some guy poured desert sand right into the chamber and bolt area. Of course it was going to fail.
But hooray - there's a PROPER burial test (finally), and here it is:

Now the bolt carrier was left open when it was buried, but if we are going to replicate the Daniel Defence AR15 torture test then by right it should be closed - and then it would have been an even greater testament to the VZ58's field hardiness.
