Reseated the hop nubber and my gun seemed fine for the first 10 or so shots then it started not firing the bb again, narrowed it down to the hop blocking the bb as the gun's feeding fine
gearbox case just above n below where nozzle is. place strips of tape to push hop unit further forward that should allow bb's to enter hop better - might lose a bit of fps but try a couple strips top/bottom
not saying it is a proper fix but more a test to see if nozzle is still not clearing 101% causing feed issue. Fix may involve 101% exact nozzle tappet plate shaving etc... but only by people who know and can fix the exact issue - like a techie but a good one
