Congrats on the purchase, and welcome to the forum.

You will find that AR's are like S&W pistols and revolvers (and potato chips), you can't have just one.

As other members have mentioned, mags are still available and at reasonable prices, stock up if you can.

Ammo, different story, at least where I am. I suppose that's the rest of the country. But anyway...

Good luck and enjoy it.
