If your magazine is the indented base it is very difficult to disassemble. The best method to clean is to put it in boiling water to remove gunk, then dry and oil. If it is a split or T-tail base, with magazing upside down lift up on T and push to the front to remove base. Then spring and follower are removed from bottom. Submersing in boiling water first will help to loosen up dirt and dried grease that may be present. Regards,
