FULLY AUTOMATIC. I squeeze the trigger and it keeps shooting about 10 times automatically?

if you get a leak at the transfer port it'll blow gas back into the main tube, pushing the hammer back, and causing that extreme hammer bounce you're hearing. Check the transfer port seal. I think Roy does the poly-tube transfer port mod on his guns, that's the first thing I'd look at.
