The OnneX Thumb is built off the culmination of all the thumb releases that STAN has ever made to give the best and fastest firing mechanism we have ever engineered. The OnneX Clicker is a completely new evolution of using a thumb button. Working with Joel Turner of Shot IQ, we were able to create the best combination of a thumb button with the huge benefits of a click. The proven Shot IQ techniques to calm the aiming and shooting process work perfectly with the OnneX Clicker!
