In the former U.S. law, the legal term
****ault weapon included certain specific semi-automatic firearm models by name (e.g., Colt
AR-15,
TEC-9, non-select-fire
AK-47s produced by three manufacturers, and
Uzis) and other semi-automatic firearms because they possess a minimum set of cosmetic features from the following list of features:

A semi-automatic
Yugoslavian M70AB2 rifle.

An Intratec
TEC-DC9 with 32-round magazine; a semi-automatic pistol formerly classified as an ****ault Weapon under Federal Law.
Semi-automatic rifles able to accept detachable magazines and two or more of the following:
Semi-automatic pistols with detachable magazines and two or more of the following:

Semi-automatic shotguns with two or more of the following:

The Act also defined and banned 'large capacity ammunition feeding devices' in the ban, which generally applied to magazines or other ammunition feeding devices with capacities of greater than a certain number of rounds, and that up to the time of the Act were considered normal or factory magazines. Media and popular culture referred to these as '
high capacity magazines or feeding devices'. Depending on the locality and type of firearm, the cutoff between a 'normal' capacity and 'high' capacity magazine was 3, 7, 10, 12, 15, or 20 rounds.
The now defunct federal ban set the limit at 10 rounds.
