Hello again,
Quick update, I tried to assemble my upper last night, and the dust cover spring went straight through the Cerakote to the metal like there was nothing there (under its own spring tension). This honestly shocked me, as I've heard about Cerakote's great durability. I took a scotch-brite pad and after 4 swipes with minimal pressure, there was metal showing.
My gut is that CMS Armory applied this incorrectly, and that the durability is nonexistent as a result. When I asked for a refund, Doug at CMS Armory told me that this wear is outside the testing parameters for the durability of Cerakote. I'm pretty upset about this.
Here are pictures of the damage
Can anyone chime in with personal experience?
Thank you.
