During our molding process, sometimes we will get product shoots that aren't perfect. We sort them because we only want to ship the best products to our customers. We have been asked before if we have imperfect products, and we have a handful of them available now. The picture shows some of the blemishes from the molding process, but likely these look significantly better than what you're currently using.
Please make sure that you understand that these parts don't look perfect.
This is the replacement buttpad for your Sig 556 and Sig 552 on your factory Sig Stock.
