Anodizing or aluminum seems weak - Timber Creek AR Billet Dust Cover

The anodizing was scratched off/dented the first time it opened and hit the lower, Haven't even taken it to the range yet. but just testing function of the new build I can see it denting deeper. I realize no parts will be scratch free for long but wow on the first time doing the only job its meant to do? I have another ar that has seen thousands of rounds and dust cover looks brand new still.
I dunno if the aluminum is weaker or just poor ano. Other than that, it works fine, I do love the color. (orange) Will see how it is long term but I don't expect any functional issues, just a little salty about the immediately cosmetic damage. Fit well on Faxon upper.
