I'm going to have to disagree with you there. If you were talking about the AES10 then yes it's more or less a WASR with extended barrel. If you go with the AES10B or Yugo M72 then you'll get all the advantages of an RPK except of course the full atuo.WASR. a civvy legal RPK is a heavier built, longer barreled AK with none of the full auto advantages that makes an RPK a SAW anyway. The longer barrel in an AK set up actually makes it a little less accurate, because the lower tolerances that make the system work so reliably also allow for a LOT of barrel wobble and torque. I think the RPK has a heavier barrel- so barrel torgue may not be the big issue I think it is.
