Instructions
Unscrew the cocking rod that is at the back of the gun and remove it. The cocking rod looks like a long metal cylinder.
Insert the Allen wrench that was supplied with your Autococker Trilogy Pro into the hole you removed the cocking rod from and turn it to adjust your gun's velocity. By turning the wrench clockwise, you can increase the rate at which your Autococker Trilogy Pro fires; to decrease it, turn the Allen wrench counterclockwise.
Remove the Allen wrench and firmly screw the cocking rod back in place.
