It depends on the use of the weapon.
Using Set Screws or Clamping Screws means a decent hit against something or drop/fall will kill your zero, and possibly make the gun a single shot. Rapid Fire can cause Set Screws, or Clamping Screws to break loose.
I thought spikes pinned all of theirs...but i'll go take it out and look in a bit. I hope it's pinned. I know my BCM is.
