AWB and stripped lower question
So I got to thinking . If there were to be another similar AWB . If they grandfathered in guns you already own , Would the stripped lower be all you need prior to the ban to then put any bells and whistles on it you want .
Example - The new AWB states no more flash hiders or collapsible stock on new production guns but if you had these things before the law took effect you can keep them .
Would all one really need is the stripped lower to be completely grandfathered in ? I don't remember how it worked last time .
And for the sake of argument . If there was confiscation of said firearms would the stripped lower be all you need to turn in ?
