I've had 2 AKs and offer the following opinion....
If you get one, get one that's a standard AK, ie; 7.62x39 and accepts all the standard AK stuff. You'll be much happier and will be able to enjoy all the various products available such as magazines, flash suppressors, bipods, stocks, scopes, etc.
I had one in .223 and had trouble finding mags that would fit, plus reliability issues. Continually jammed. Plus I spent a bundle on magazines for it and half of them didn't work. Swapped it for a standard AK (Romanian) and it worked flawlessly. My brothers have the same thing and swear by them.
If you get one of the Romanian AKs, they now come with a bayonet and other cool toys that weren't available when I got mine.
Food for thought. Hope it helps.
