From memory I believe it contained wording like "Applies to specific weapons and all derivatives" and listed things like M1 Carbine, Bushmaster XM15, Armalite AR-10/AR-15, Ruger Mini-14, SKS, Saiga, Thompson, etc... however I have some doubts on the accuracy because it also contained specifically named weapons that are already part of NFA (some older H&K models) along with some that in so far as I am aware were never on the civilian market.
It was also worded to ban anything that had a collapsible/folding stock, *any* forward grip, and of course anything with the shoulder thing that goes up (barrel shroud).
Then again Feinstien apparently did some really good research...(from http://www.nraila.org/legislation/feder ... -bill.aspx):
Indicating the depth of her research on the issue, she said on Dec. 21st that she had personally looked at pictures of guns in 1993, and again in 2012
