One of the biggest complaints about the M-Press is the die blocks. These will replace a die block, and allow you to use you standard die lock ring sets. These will allow you to remove the die/lock ring and place a new die/lock ring in place, all without having to buy new die blocks or lock rings. These were designed to be able to adjust the die without the lock ring spinning. Print on the bottom face with the text. No supports needed.

Currently have the Lee Spline and Hex lock rings attached. Working on the RCBS and Hornady lock rings next.
