The Bureau of Alcohol, Tobacco, Firearms, and Explosives has put the draft version of Form 3310.12 online. It is the form that will be used by FFL’s in the Southwest to report multiple sales of certain rifles.
The draft form is virtually identical to the form used to report multiple sales of handguns. That form, ATF F 3310.4, differs in one important way from the draft form to be used to report multiple sales of certain rifles. The difference is that the report of sales of semiautomatic rifles with a detachable magazine in calibers larger than .22 will not have to be reported to local law enforcement authorities unlike multiple sales of handguns.
I guess one should be thankful for small favors if you are a resident of the Southwest.
