This is funny, and one of the reasons I debate about guns......because of your question about the number....I found a new number...a better number, from an anti-gun source....which means the anti-gunners will hate it....even more...
This goes to 2012.....and reports 2 million new rifles each year....so adding that to the total.......
34,000 million semi-automatic rifles now in 2019 that the anti-gun morons would want banned......
How Many Assault Weapons Do Americans Own?
In raw numbers, American gunmakers produced and imported 8.5 million such rifles between 1990 and 2012, and about one and two million annually every year since.

Do the math and it works out to between 15 and 20 million modern sporting rifles now in circulation. (An important note: The NSSF report includes weapons produced for law enforcement.)

Nonetheless, according to CNN, the AR-15 is now perhaps the most popular single model of rifle in the country. And the overall number of assault-style weapons in the United States is not just an academic matter: the constitutionality of gun bans rests on their historic popularity.
