Is it normal for the mounting and removal of a KAC suppressor to remove the finish from a KAC Muzzle device?

Muzzle device is KAC 3 Prong (factory installed on KAC Upper) and the Suppressor is KAC 5.56mm QDC/CRS-PRT.

I have mounted the KAC Suppressor approximately 2-3 times and I am noticing the finish scraping/wearing off of the muzzle device in a particular area.

I’m noticing the same thing with my M4QD. This is after 100 rounds and removing the NT4 only a handful of times.

Just wait until they turn green from the copper residue!

I reached out to Knights and they said the wear looked normal, so i’m just going to keep running it.

Thank you to everyone that commented.  

Good to know that it is normal and not something I need to address.

I haven't experienced finish wear on Surefire Muzzle devices from my RC2, and this is what prompted my question.
