Good but not great - Timber Creek Ambidextrous Safety Selector

I originally bought these for my AR-10 with a Aero Precision lower and they worked fine but I felt that the right selector was a bit too low profile for my likes and they were a bit on the sharp side due to the machining process(minor gripe). I moved them to my AR-15 with a generic lower with the bump stops above the selector and found that the left side would make contact with rear stop causing a slight amount of damage to the selector, it did not impede function but just be aware slight marring will occur(minor gripe).
