The Tadao PMR/PM7 board is a drop-in replacement for the Proto Matrix Rail and Proto Matrix 07 stock boards, and uses the feature-packed Musashi 7 software. The circuit board is the most important part of any electronic paintball marker, and upgrading it can enhance all the performance characteristics. Tadao's leading edge Musashi 7 software provides the user with the ultimate in adjustability and speed. Like most other Musashi 7 based boards, the Tadao PMR/PM7 board includes a simple trigger based programming interface for changing virtually any setting, and an ultra bright 7 color LED that is more visible through the grip frame.
