Is this marred anodizing a problem?
I was working on a new build today and decided to do a dress-rehearsal for the installation of a Magpul UBR (my Hammerhead tool hasn't arrived yet, so I was just checking fit and function). The UBR was pretty snug on the receiver extension, but nothing outrageous (I didn't have to use a mallet, which the instructions said might be necessary).
After I removed the UBR from the receiver extension (again, it didn't take too much effort--it was just snug), I noticed that some of the anodizing was taken off of the receiver extension, like so:

Obviously, this will never be seen once the UBR is installed again. My only question is if this marring of the anodizing is an invitation for rust to begin forming in the RE, and if so, is there a way I can head this off?

Fun fact, an analog to iron rusting is aluminum thermite. Sort of.
Similar problem on my brand new BCM upper...
Hi everyone, first post here, but I've been lurking for a while. This thread finally prompted me to post. I'm looking for some help with my brand new BCM upper.
I finally snagged one off their site and when I pulled it out of the box to put in my BCG I noticed the marred finish....is this just another candidate for Alumablack?
I've been trying to get this upper for a year now, and now that I have it, this stupid little mark is keeping me awake at night...advice is welcome, thanks!
