Atlatl could be carried loaded at warrior's side, when ready to throw, simply hold over shoulder, depress trigger, projectile will pop out, telescope, and fling away. The finger guard will keep the projectile from impaling your hand. It should also be noted that the notch that holds the spear in place will keep it from launching off the atlatl under its own spring loaded power. Kind of like a trebuchet hook, it wont let go until the proper angle is reached. There will be 6 of them on a rotating spindle so they lock each spear in when they pop out.
