I want to clarify my experience.
I had 2 mounts. One of them was holding a ZCO 527 and the other a S&B 6-36. When the mounts were removed, yes there was “aluminum transfer” but that was not the issue, I just wiped that off with some alcohol.
On both scopes all around the edges where the rings end there were marks that were not removable. Both mounts were torqued to 15in lbs using fix it sticks. Now, was there an issue with the 2 mounts I had or an issue with the finish on my scopes? Am not sure, maybe If I owned the mighty Arken I wouldn’t have had this problem.
I also would like to clarify that I think Area 419 makes great products and I will continue to be their customer because my experience with them has always been positive aside from this one experience. I have own a few pairs of their match rings in the past as well and never had any issues with them or any of the other items I own.
