Got in some practice today with my brother, Possum Trot Pete. He shot the 1st stage, then I shot it. As I was picking up my rifle I found this part laying on the table we was shooting from. We both shoot Taylor Uberti 1873 Comanchero’s and CZ Sharptail Coach guns. We are confident this part did not come from our guns. It’s roughly 3/4” long, the round end is slotted for a screwdriver and appears to be blued. Identifying the part might help in getting it back to its owner. What is it and what gun would it fit ?
