I suspect it’s much less than 1.8%. Assault rifles aren’t nearly as common as all other types of rifles. They’re estimated to be approx. 1% of all the rifles in the country.
Thanks to Obama, Cuomo, Feinstein, Lieberman, et al, the sales of AR-type weapons are skyrocketing. I suspect all the manufacturers are gearing up for multiple shift production.
I think there’s probably a lot more assault rifles out there than that. Even at 1% of all firearms, that’s only around 2 million assault rifles. I suspect there’s actually 10-20 million of them out there, perhaps more.
