Hey, my buddy has come across an M90A 1997 kit and wants to know what its worth. I saw the front end, that he had with him. The barrel 5.56 1/7 looked new. I don't know squat about AK's. The barrel is short and heavy with a bird cage flash hider, flip-up night sight, black furniture. What is the configuration of the back end? Does the rear end have a folder or fixed stock? Any Help is greatly appreciated, Thanks in Advance to any and all responses. The receiver is a lot heavier than the one I built. What is the value of a complete kit?
