A friend went through the local LE sign off for converting a rifle to an SBR. Several months ago the Travis County Sheriff promptly signed and returned his form which was then sent off the ATF. Last week my friend was in Florida when he had an encounter with the police in which they ran his ID. The encounter due to a simple misunderstanding and no trouble ensued. However, when the Florida cop ran his ID my friend overheard it reported back that he has a "Class III weapons permit". It appears that the Sheriff somehow added this information to whatever data base they search when running an ID. Given the paperwork has not even cleared yet with the ATF there is no other possible source. Is this normal?
