the only thing that comes to my mind that fits that description is the RRA PDS series. RRA is rock river arms. functionally its very similar to an ak with the weight factor and accuracy of a ar15.
Rock River Arms: RRA LAR-PDS Series
personally i dont care for the hk mp5 style charging handles on the pds but thats just me. the sample i saw in person but didnt get to shoot as the owner didnt offer was surprisingly light for a non dgi gun.
one you pop the takedown pin out it comes apart very much like an ak47 with a similar spring/guide rod and bolt carrier/bolt setup to the ak47.
