Deformation after 500 rounds - Strike Industries Checkmate Compensator

I put this on a quality build and after 500 rounds I noticed sharp edge and bulging on front portion. It is blown back into the break port area. I contacted Strike Industries to seek their opinion of what was going on and if it was safe. They went into defense and stated it was carbon build up and i could go pound sand. Completely unhelpful, overly defensive and in my opinion not worth it…I will move on.
