Search for the thread on Aftermath Kraken AK47's, pretty much all good.
They aren't crap despite what the very few say. Only $150 max. totally TM compatible thus upgradeable. Great fps, durability (mine played two years and Claybank with no probs whatsoever), comes with a hicap mag (though I would get a better one sooner than later) surprisingly good accuracy.
Aftermath may have made a mistake...the whole you get what you pay for thing...well, doesn't compute here. The Kraken is a decent gun for the price bar none.
