I was just reading the latest copy of American Rifleman and see there is a safety recall on the KelTec Sub-2000 carbines manufactured in 2017. The article says that if you bought a Sub-2000 during the years 2017 or 2018, you should discontinue firing it until you check to see if your gun is affected. Phone number is (321) 631-0068, extension 136, Mon-Fri, 9am-4pm. It caught my eye because I bought one early in 2017 and sold it in February, to the finance manager at the car dealer where I bought my KIA. I just called him and gave him the contact phone number.
