If you already have an AR, then go with an AK. It'll double your chances to find some ammo once Trump gets impeached/arkancided or committed in some mental institution.
It would be a great choice. Make sure to get the Volquartsen trigger kit for it. You will have so much fun with it, and actually look forward to cleaning it because the takedown and reassembly is so easy.
Picked up a G19 with prebans in anticipation grabbing a kel-tec. The CZ is really nice but to comply with Mass law I would have to run cripple mags and pin the stock etc. kinda defeats the purpose.
