Fwb300SU adjustable cheek piece broken?

Depends if it's a gen one or gen two or gen 3. One and 2 have fixed cheek pieces but come with a high or low option, gen 3 is adjustable. This is my gen 1 below with high cheek piece installed, low one is below on the right... Gen 3 will have stippling all the way back to the trigger guard.
