FRANKLIN ARMORY DFM Magazine 5rd

FRANKLIN ARMORY DFM Magazine 5rd. The Franklin Armory DFM Magazine easily converts your AR into a fixed magazine design with no permanent alterations required. The DFM is designed to be used with a magazine catch. This prevents the tabs from resting on the lower receiver. If the magazine is allowed to reside below the magazine catch, the tabs may mark the lower receiver. In addition, the feed lips of the DFM will likely sit too low for proper functioning.
