First of all how old is the Mini? I would make the trade if it were a 580 or newer series Mini (look at the serial #). If it's an older Mini make sure you shoot it before you make the trade some of the older rifles suffered from barrel whip caused by the skinny barrels. Some of those older Minis shot groups that could best be described as minute of basketball. It doesn't sound to me like you're particularly attached to the AK so not much reason to hold on to it unless you're keeping it as an investment. If the Mini shoots good make the trade, if not walk away.
