There's AK's, then there's AK's. Romanian, Yugo, Russian, Saiga, CAI-rebuilds...
Same thing for AR's.
Good AK's go for about the same price point as new bottom-bucket AR's. Dealer-special lowers (plum crazy, cavalry arms, inexpensive aluminum offerings) and a lowest-tier parts kit, coupled with an inexpensive upper will get you out to the range for $600 + cost of mags. Or you can let Century rebuild a 1:12 twist Colt/FN upper onto a new bottom-end lower for $630 @ J&G.
But AK's can still be found for less than that bucket-o-parts lowest common denominator AR.
J&G is still selling Romanian WASR's for $400 to $450 depending on quality, or SKS's for as low as $270.
You ought to head down here, Balog. Come with a couple grand, head to J&G, pick up a new AK or 3, and a few cases of ammo. Get yourself on that nice, shiny ATF "watch list" they're mocking up for the 4 border States.
