I was surprised by the amount of scratches in the finish for a new product. The compression bolt was pre-installed. I pulled it out and it wouldn't go back in. Stopped after half a turn and the black finish on the bolt showed signs of impending stripping. I'm going to purchase a tap to clean the threads. All these complaints have nothing to do with Source, I just wanted to vent. Source is on the same side of the country as me so shipping is fairly quick, which is nice.
