You can still buy all the 5.56 ammunition that you are strong enough to carry out the front door. There’s tons of money for them to make just in that particular caliber.
So, you can’t buy AR15’s or their magazines. But, you can feed them to 30 round bliss in your current magazines with ammunition bought from them.
Even cheaper prices at Dick’s ^Going Out of Business^ sale later.
I could do that but I won’t.
Some other seller will get all my business and Dick’s will get ... zero.
