The Act prohibited the manufacture, 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]
