This board replaces the stock board on the ESP frame. dwell time is less than 4 miliseconds. There is no shot queuing at all. They say Anti-Chop eyes are compatible. They increased the feed rate of an Evolution 2 from 15 to 22 bps with this board. There is no scanning for trigger pulls so its faster. One pull=one shot.
Never entered production.
The Apocalypse Custom Paintball Kinetic Board is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
