RESOLUTION OF MODERN MUZZLE
LOADING COURT CASE
ATF has received a favorable decision in the case
Modern Muzzleloading, Inc. v. Magaw, No. 97-
2956 (TAF) (D.D.C. Aug. 8, 1988).
This case involved a challenge to ATF’s
classification of plaintiff’s Knight Disc Rifle as a
“firearm” for purposes of the Gun Control Act.
The Knight Disc Rifle is an in-line modern
muzzle loading rifle, which interchangeably uses
either a percussion cap or a shotgun primer as an
ignition system. Plaintiff claims the Knight Disc
Rifle should be classified as an “antique firearm”
and not regulated as a “firearm” under the Gun
Control Act.
The District Court held that ATF properly
classified the Knight Disc Rifle as firearms since
it utilizes a modern centerfire shotgun primer, not
an antique ignition system. The Court rejected
plaintiff’s argument that because the Gun Control
Act is a criminal statute; the rule of lenity must
apply. Rather, the court held that ATF’s
classification decision is entitled to deference and
is neither arbitrary nor capricious.
