depends. my understanding is you can still get one delivered to your door, it just can’t cross state lines.
one thing tho that has changed is the price
The AR-15 Sporter would set you back just shy of $190 — around $1,485 in 2016 [dollars]
today, you can pick up a cheap one for $500. that’s a pretty significant price drop, even as the guns themselves have gotten more reliable and more accurate
ammo’s also cheaper and more deadly. the gun and its ammo is much more accessible now - several dozen of manufactures; not just one. plus who even knew what it was then? ( pretty much no one. ) having and owning a gun like that now is cool and manly. ( that’d be funny if it weren’t true. )
so yeah, lots of things have changed. including gun culture. maybe americans just can’t be trusted with guns any more, and once upon a time they could? who knows.
doesn’t really matter what’s changed. just that it has. we’ve got these other even cooler tools called laws that we can use to help reduce the number of murders and suicides. sounds like a win to me.
