I had a C&R license several years ago and bought and sold a few C&R rifles and handguns. Anyhow, I get an email today from DOJ that they are doing a trace analysis on a Yugoslavian SKS I purchased back in 2002 and want to know if I still have it. I called them and they said Law Enforcement has asked for a trace on this rifle and that is all they could tell me. I had sold this rifle and gave them the name and address of the C&R holder who got it back in 2004, thanks to my bound book I had the info. My question. Should I be worried? Is this routine? What is the deal? Thanks!
