AR15 Magwell Kit

The duMONT Company’s AR15 Magwell Lower Kit contains 3 holders, 3 types of inserts and a replacement set of inserts, 2 drivers, and an alignment tool all in a durable case. This kit allows all broaching of a magwell lower receiver to be done within the CNC cycle. The need for a secondary broaching process in a separate special purpose broaching machine is eliminated!
