This is a simple macro that provides automatic firing for semi-automatic weapons. It is important to note that it does not affect returns. Given the shooting speed limit in Rainbow Six Siege, the delay is approximately 64 ms, which also allows for single shots. The macro is activated by clicking on the middle mouse button, which allows you to use the left button for a macro that already affects the return. Don't forget to reassign the middle button as the shooting button in the game settings.
