EFFECTIVE DATE :
The bill will take effect immediately except where otherwise provided.
That is all I could find that talks in detail about the mag capacity, however, I can't find an actual effective date, in fact, looking through this, there isn't an effective date anywhere, even though I know the ammo background checks/reporting to state etc will start at the beginning of next year. I know I've heard the march effective date on mags from several sources. mid-march to mid-april are the date ranges I've seen/heard, so where did that come from? Clearly not from this page...
