My friend has the Marker and it will only fire one shot at a time at a very slow pace. whenever he tries to fire at a faster pace the gun stops shooting, the lights flash green and the trigger has a click from the solenoid but no shot. once he stops waits and fires one shot he can continue shooting only if he waits 2-3 seconds between shots. Air pressure is good. Gun was cleaned and Lubed. Although i didn't open up the reg. Any thoughts on what this could be and or how to fix this?
Thanks For the help
