If anyone remembers the old school days, tippmann had three Factory Full Auto, Non Electric, Non response trigger guns.
the VM-60, VM-68, and Tippmann Factory F/A (full auto)
here is a diagram of the Tippmann F/A

As you can see...tippmann has NOT changed their basic engineering of their guns for over 15 years...from their first semi autos, to the a-5's, tippmann has been using the basic, Bolt, Powertube / Valve, Hammer, Hammer spring, Spring Guide, Back plate, and connecting rod configuration for many, many years.
This same style of engineering applies to their Factory full auto guns. On their Factory F/A's, one could actually TUNE the Rate of Fire with the Brass ROF Adjustment screws.
If anyone has a Factory F/A, maybe they can enlighten us on how they managed to get their Full Auto to work.
