Supposedly, it does not impact ammo imports…that said, don’t count on that for a second.
If you can afford it, buy it now. As much as you can if you have an AK/SKS already. By the time it is banned, it is too late, and the costs will be crippling. Without reload supplies, there aren’t many solid options if/when that happens.
That said, if I were you, I’d have an AR or FAL as an alternative. 5.56/.223 and 7.62×51/.308 are more common, and reload supplies are readily available.
