I don't see a ban on parts at the time except for hi-cap magazines.
The Act prohibited the manufacture, sale transfer, or possession of "semiautomatic assault weapons" as defined by the Act. "Weapons banned were identified either by specific make or model (including copies or duplicates thereof, in any caliber), or by specific characteristics that slightly varied according to whether the weapon was a pistol, rifle, or shotgun" (see below).[11] The Act also prohibited the transfer and possession of "large capacity ammunition feeding devices" (LCAFDs). An LCAFD was defined as "any magazine, belt, drum, feed strip, or similar device manufactured after the date [of the act] that has the capacity of, or that can be readily restored or converted to accept, more than 10 rounds of ammunition."[11]
The Act included a number of exemptions and exclusions from its prohibitions:
* The Act included a "grandfather clause" that allowed for the possession and transfer of weapons and ammunition that "were otherwise lawfully possessed on the date of enactment."[11]
* The Act exempted some 650 firearm types or models, including various types of Browning, Remington, and Beretta guns, as these were viewed as primarily "suitable for target practice, match competition, hunting, and similar sporting purposes. 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.'"[11]
* 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."[11]
* 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."[11]
* 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, "as well as possession by retired law enforcement officers who are not otherwise a prohibited possessor under law."[11]
In 1989, prior to the enactment of the 1994 legislation, the George H. W. Bush administration had banned the importation of foreign-made, semiautomatic rifles deemed not to have "a legitimate sporting use." It did not affect similar but domestically manufactured rifles.[12] (The Gun Control Act of 1968 gives discretion to the Attorney General of the United States to choose whether to "authorize a firearm or ammunition to be imported or brought into the United States" under what is known as "the sporting purposes test."[11]) Following the enactment of the Federal Assault Weapons Ban, the ATF determined that "certain semiautomatic assault rifles could no longer be imported even though they were permitted to be imported under the 1989 'sporting purposes test' because they had been modified to remove all of their military features other than the ability to accept a detachable magazine," and so in April 1998 "prohibited the importation of 56 such rifles, determining that they did not meet the 'sporting purposes test.'"[11]
