ZKKs with pop up peeps are getting hard to find in Australia and when found the complete gun is getting close to $1k remembering you are buying a stock and barrel which you do not want. Of course you could sell these and get some money back.
Personally I would go with an 09 Argy. While I love the ZKKs IMHO they are not pure Mauser actions. Something about that bolt release gets me in every time.
