So i bought an AK from my local gunshop. mk99 ITM arms co., lancaster (goodyear, az.) are the markings on the reciever. This thing refuses to chamber a round after a shot. I cant tell if its the mags or the rifle. Ive tried 4 different mags including one polymer. Still is being touchy. I dont like have nonfunctional weapons taking up space in my safe. any suggestions, anyone else had this problem?
