Charlie NC, you are correct. In my case anyway. I had to wield a bead on the magazine at the latch point then file it down to where the release lever would just engage the magazine with the magazine pushed up tight to the action. Then I had to file down the feed lips so that they would clear the bolt and at the same time bend them in to hold the rounds. Its a slow and tedious process and if it isn't done right you'll make the feed lips to short! Also you need a tool that looks like pliers that are about 2" wide so that you can bend the whole lip at once. Mine work fine now.
