Has there ever been a recall on the GSG-5 Breech of any sort? Cleaning I noticed a hole that I don't think is supposed to be there and noticed the other side looks like it could break through as well. Having all kinds of jams and I'm wondering if I have a lemon or a bad batch of these things got released at some point. This is from a Gen 2 GSG-5 with under 500 rounds through it. Looking at the other side it looks like its breaking in from the outside as its dented in not dented out which seems odd.
