If everybody is good with the guns going to you, then there should be no problem regarding the non-banned items because whoever is the beneficiary under the residuary clause, she could gift them to you. If you happen to be a partial beneficiary under the residuary clause, then you can take the handguns, might even be able to take the banned assault weapons too. Thing is, showing that you inherited them properly.
A disclaimer can also be used if the guns would flow to you via the Will should somebody disclaim. Really, these are things that need to be discussed with the attorney with the Will in front of him. A lot of speculation on my part and what ifs, but how the Will is drafted will control what your options are.
Anderson76 put it more eloquently and in legalese, but he is right. If you can get your mom and sisters to disclaim their interest in the firearms, and your sisters do not have any children if the division in the Will is per stirpes, then the guns can flow to you. If your sisters have children and the division is per stirpes, you can get them to disclaim too. If they have minor children, things get a little more complicated.
