This list was not exhaustive and the act provided that the absence of a firearm from the exempted list did not mean it was banned unless it met the definition of 'semiautomatic assault weapon.'"[14] The Act "also exempted any firearm that (1) is manually operated by bolt, pump, lever, or slide action; (2) has been rendered permanently inoperable; or (3) is an antique firearm".[14] The Act "also did not apply to any semiautomatic rifle that cannot accept a detachable magazine that holds more than five rounds of ammunition nor any semiautomatic shotgun that cannot hold more than five rounds of ammunition in a fixed or detachable magazine".[14] The Act provided an exemption for the use of "semiautomatic assault weapons and LCAFDs to be manufactured for, transferred to, and possessed by law enforcement and for authorized testing or experimentation purposes", as well as transfers for federal-security purposes under the Atomic Energy Act and "possession by retired law enforcement officers who are not otherwise a prohibited possessor under law".[14]
