During the 1994 ban to which you refer, Congress banned the sale of new semi-automatic weapons (one trigger pull, one bullet fired) under certain trademarks (like AR-15™) and with certain cosmetic features (like bayonet lugs, and pistol grips on imported rifles).
We didn't actually ban ownership of assault weapons. There was no confiscation. People were allowed to retain the weapons they already had, and they were allowed to buy new weapons. Is that the position you are advocating?...Let everyone own what they have, and let them buy new ones that just look different (e.g., no bayonet lugs) and are marketed under new trademarks (e.g., AR-15™ brand rifles are prohibited, but identical/similar Sporter™ brand rifles are permitted)? If so, then I know you aren't serious about gun banning. You are just trying to give talking points to low information voters and motivate your party base.
By the way, be careful arguing about the potential military use of the weapons you want to ban. SCOTUS has indicated that military style rifles are exactly the types of arms which are meant to be protected under the Second Amendment. You would do better arguing that they have only sporting use.
