ATTRIBUTES, AND IMPLICATIONS REGARDING
LEGISLATION

ABSTRACT
Many legislative sessions and court arguments have examined the
constitutionality of restrictions or bans on specific firearms or attributes,
including assault weapons. These legal debates justifiably focus on the
specific legislative language, intent, and precedent applicable to the discussion.
Few of these legal debates focus on the practical implications these firearms
laws and adjudications have on the types and choices offirearms available-or
not available-to consumers and citizens. This research focuses on the general
contours of the legal concept of assault weapons and presents a quantitative
analysis of the impacts of assault weapons bans, and not on the
constitutionality of the laws themselves.
Looking at various definitions of an assault weapon in four proposed or
enacted federal and state bans, we test which small arms currently available to
American consumers would fit the various legislative criteria of assault weapon
and thus be banned from new purchase by consumers. Of 199 models of
centerfire rifles with semi-automatic firing advertised in a 2019 mass market
gun magazine, we find roughly 70-85% would meet the ban criteria. In
contrast, at most 15% of the currently available semi-automatic shotguns and
only 1.5% of semi-automatic pistols would meet ban criteria. As a percentage
of all rifles, shotguns, and handguns currently available, the banned firearms
percentages would be approximately 20%, 5%, and 1% respectively. The legal
profession should better understand this effect on consumer choice offirearms
availability to gauge its intent in assault weapon bans versus its practical
impact.
We also analyze the frequency with which legislatively designated assault
weapons traits appear among those weapons that meet ban criteria, and use
