This information is not an official statement by any government agency, manufacturer, or any other entity. Data presented here is correct to the best of the webmaster’s knowledge. No warranty or guarantee of any kind is made concerning the accuracy of the following information.
18 U.S.C. sec. 921 (a) (30) (B). Traditionally, the frame or receiver of a firearm has been legally equivalent to the firearm itself. 18 U.S.C. sec. 921 (a) (3). This has led some people to believe that a pre-ban receiver, that is, one manufactured before 9/13/94, is the same as a pre-ban "assault weapon." Unfortunately, this is not correct.
Simply because lower receiver has a "pre-ban" serial number does not necessarily mean that the firearm was assembled prior to the ban, only that the receiver was manufactured before the effective date of the ban. In order for an assault weapon to be "grandfathered", it must have been configured as an assault weapon prior to the ban (the effective date of the ban was September 13, 1994.)
Possession of a post-ban firearm in an "assault weapon" configuration is a felony unless it is possessed in accordance with one of the Federal exceptions.
If a stripped lower receiver was in a dealer's bound book at the time the ban took effect, and it is later discovered in an assault weapon configuration, it could be rather easily ascertained that it is not a grandfathered firearm. Receivers in private hands on the day of the ban are a little more ambiguous as who is to say if it was or was not in an assault weapon configuration on the date of the ban, and then later stripped? As always, buyer beware.
Relax, we had to use the term "assault weapon" because that’s the name these types of firearms were given by the folks who wrote the laws.
According to the law, a rifle is an "assault weapon" if it has a detachable magazine, and two or more of the following:
A folding or telescoping stock.
A pistol grip that protrudes conspicuously beneath the action.
A bayonet mount.
A flash suppressor or threaded barrel designed to accommodate a flash suppressor.
A grenade launcher.
