In the United States, full-automatic firearms are legal in most states, but have requirements for registration andrestriction under federal law. The National Firearms Act of 1934 required approval of the local police chief and the payment of a 200$ tax for inital registration and for each transfer. The Gun Control Act of 1968 prohibited imports of all "nonsporting" firearms, and created several new catagories of restricted firearms. The act also Prohibited further registery of most automatic firearms. The Gun Owner's Potection Act of 1986 imposed restrictions on some semiautomatic weapons and banned manufacture of machine gun in the United States. (Except for govrnment purposes) Currently, all must have been manufactured and registered before May 19, 1986; a $200 transfer tax must be paid; approval must be met in writing prior to purchase from the local sheriff or chief of police; fingerprints and a photograph must be submitted to the ATF; a criminal background and mental health check must be performed. This process can take 4 to 6 months to complete. Written permission must be given by the ATF at least 30 days in advance if one wishes to take his full-automatic firearm out of his state. Due to the static number of full-automatic firearms on the market (fixed at 1968, 1986 levels), their collective value continues to increase. Most full-automatic firearms for sale cost in excess of $8,000USD, which is for many seeking to make a legal purchase the most prohibitive factor. Several states have decided to prohibit the sale of full-automatic firearms altogether. In most US states however, one can buy semi-automatic firearms over the counter if the buyer meets basic legal requirements, and after completing the proper paperwork and a criminal background check (and in some states, a waiting period).
