I am active military and was registering firearms on post when the Springfield M1A I had just purchased came up flagged. Apparently a similar rifle, although different model and one much older, had been stolen previously and my rifle had the same serial number. After an hour of waiting and conversing with an investigator I was told that whereever I take the rifle I should also carry any and all paperwork I have regarding it just in case. I was looking around online and by the lack of results, I am assuming this is not a common occurrence. I am considering selling the rifle and buying a new one (at potentially several hundred dollar loss) just to avoid any future headaches that might arise from this. Does anyone know if this is common and if I should be concerned? To me this seems like a liability as any potential entanglements with law enforcement could get ugly if they run the serial number on this rifle.
