So I have been building a custom AR lower and I'm almost ready to purchase the upper and finish it. My issue is for less than my upper I can buy a complete AK, furthermore the price of ammo is about half, I could shoot an AK all day and not care about how much I just spent! For the $700-$800 range what would you guys recommend, my friendly local gun store has a CIA for $639. It seems the only thing on an AK that costs more is the mags. Lastly, anyone have an opinion on AK74's?
