That's an AW under the new bill too.Grab yourself a Ruger Ranch Mini14. Plenty of preban mags available. Convince yourself that it is just as good, and if it just sits in you safe - it is. Then go out shopping for a SKS and remember how these could be bought for less than $100 not terribly long ago.
At the end of the day, you can buy or build an AR today and if the law passes have to turn it in sometime next year.
You can wait to see if the law passes and then make your decision, if the law doesn't pass you've lost two months of ownership, if the law does pass you saved yourself a grand or so along with the luxury of potentially being a felon, 2a advocate plaintiff, etc.
It doesn't sound like you're ready to own a AR if the law changes, so you may as well hold off and see if it does.
