Well, if I had a country there would be a lot of people in trouble, but..
I have two of these and have used them a lot. The AR is light and the ammo is light. The AK style is cheap and not very handy to operate, reliable and has a pretty good compromise round.
The FAL style has a good round and is user friendly, reliable but heavier.
I say the FAL. I don't like .22 bullets for serious work and the AK style is not much lighter than the FAL so does not have a real advantage over that weapon.
