Not a legal type, but I'll take a crack at it.
Under the AWB, no new assault weapons can be manufactured after Sept 13, 1994. Additionally, in order for an AW to be grandfathered, it had to be assembled as a complete weapon prior to the ban... IOW, if someone had a stripped lower receiver that was manufactured prior to 9/13/94, then days, months, years later decided to assemble it into a complete rifle, they would be manufacturing a new AW in violation of the ban.
http://www.impactsites2000.com/site3/prepost.htmWhat Brady and Co are claiming is that the ATF is allowing the manufacture of
new assault weapons.
The ATF's position is that it is allowable for pre-ban receivers to be replaced if damaged. If it's a repair or replacement to a previously owned (and legal) AW then there is no manufacturing of a
new AW.
http://www.atf.gov/firearms/faq/faq2.htm#o7"O7) Are replacement parts for grandfathered semiautomatic assault weapons and large capacity ammunition feeding devices subject to regulation under the law?
No. Parts may be replaced in grandfathered semiautomatic assault weapons and grandfathered feeding devices without violating the law. However, if the frame or a receiver for a semiautomatic assault weapon is defective, the replacement must be made by the weapon's manufacturer or importer. The replacement receiver must be parked with the same serial number as the original receiver, and the original receiver must be destroyed. However, a manufacturer or importer who is unable to mark the replacement receiver with the same serial number as the original receiver may seek a marking variance in accordance with 27 CFR 178.92. In addition, the permanent records of the manufacturer or importer should indicate that the receiver for the weapon has been replaced."
What they're alleging is that the ATF doesn't have the authority to allow even repair or replacement.
The Brady Campaign's lawsuit will allege the ATF violated the assault weapons ban by granting gun manufacturers permission to replace receivers - the firing mechanism of the gun that the law defines as the gun itself - and give pre-ban guns new serial numbers.First off, under the AWB, "semi-automatic" firearms receivers do not come under the definition of an AW.

Here's how the ATF defines it.
http://www-2.cs.cmu.edu/afs/cs/user/wbardwel/public/nfalist/atf_letter49.txtTitle 18 U.S.C., section 921(a)(7) defines the term rifle as a
weapon designed, made or remade, and intended to be fired from the
shoulder and designed or redesigned and made or remade to use the
energy of the explosive in a fixed metallic cartridge to fire only
a single projectile through a rifled bore for each single pull of
the trigger. Section 921(a)(30)(B) defines the term semiautomatic
assault rifle as a semiautomatic rifle that has the capability to
accept a detachable magazine and that has at least 2 specified
features.
The frame or receiver from a semiautomatic assault rifle does not
meet the definition of a rifle. Therefore, the frame or receiver
from a semiautomatic assault rifle, in and of itself, is not a
semiautomatic assault rifle.
*******************
Basically what it comes down to is how can a receiver be categorized as an AW when it lacks any of the features that defines an AW?
They also reason that just because the receiver was manufactured prior to the ban, it doesn't automatically mean it would be assembled
as a legally defined AW... it could be assembled in post-ban type of configuration.
Brady and Co are just grasping at straws here as it gets closer to the expiration date... they know there's little to no chance this lawsuit will see the light of day. They're just exploiting it so the AWB can become more of a political issue in the presidential election.
