Description Some of the best AK-47s in the world are of Polish origin. What we have here is an AK47 originally built in the Random, Poland factory over at Pioneer Arms then shipped over to the US where the guys at JRA (James River Armory) put their expertise at work and get it US compliant. These rifles are assembled with the original Polish barrel and receiver which have developed a reputation for being some of the best quality. A lot of custom AK builders try to source original Polish parts for this reason. Get a high quality AK-47 today without the expense of a one off custom build.
