The DM/PM "Top Hat Mod" Spacers work on any model Dye Matrix or Proto Matrix. They are designed to work with any bolt system. Whether you are using a stock bolt in your DM or PM marker, or you upgraded to the L7 bolt....this kit is a must have. We designed the spacers to give you maximum control over your marker's operating pressure.Using more spacers increases your marker's operating pressure which allows for lower dwell settings and better air efficiency.Just another nice,little way to fine tune your marker to your playing style and needs.
