Abstract

The present invention relates to the field of tools used to modify the magazines of firearms. A die and anvil are configured to engage and form the lips of magazines, like that of the M16A4 and M4A1, to correct damage and enhance the feed angle of rounds to improve feeding and accuracy. The die and anvil are provided with a means to align them during the forming process to minimize the attempts necessary to complete the forming process. The anvil is configured to enter from the base of a magazine and to engage the side walls with sufficient tolerance to allow for free movement, but tight enough to detect deformation in the side walls. The anvil can be used as a rigid surface to correct deformation of the side walls with a non-marring tool. The preferred embodiment provides sufficient force to form the feed lips of the magazine without the need for additional tools.
