Yes, I am.
For example.
The Act prohibited the manufacture, transfer, or possession of "semiautomatic assault weapons," as defined by the Act. "Weapons banned were identified either by specific make or model (including copies or duplicates thereof, in any caliber), or by specific characteristics that slightly varied according to whether the weapon was a pistol, rifle, or shotgun" (see
below).
[17] The Act also prohibited the manufacture of "large capacity ammunition feeding devices" (LCAFDs) except for sale to government, law enforcement or military, though magazines made before the effective date ("pre-ban" magazines) were legal to possess & transfer. An LCAFD was defined as "any magazine, belt, drum, feed strip, or similar device manufactured after the date [of the act] that has the capacity of, or that can be readily restored or converted to accept, more than 10 rounds of ammunition."

I don't get what the problem is.
