No other parts are stamped "US" that I noticed. The stamp looks very much like the Geissele hammer that I just purchased. The stock hammer looked browner to me, while the Geissele was black.
When I removed the old hammer I noticed that "US" was stamped on the stock hammer just like the new hammer. Anyone else have a similarly marked stock hammer?
