what do you guys think is the problem???

Sounds like either the piston rack gear is stripped or the sector gear, since you say the gears are still moving, it explains the multiple bb's due to the sector gear moving the tappet plate.

So you'll have to get that gearbox opened again.

yup i'll probably just bring it to a gun doc.
its probably time to upgrade the internals.
what do you guys recommend interns of reliability

anything by prometheus, modify or guarder will serve you just fine. assuming that the gears are fine, this is what id get if i was on a budget:

MASK Piston head
Modify Cylinder Head
Sorbo Pad
Modify Spring Guide
Modify Air nozzle
Metal bushings
If you need a new tappet plate, see if you can find one by the previously mentioned companies
(if you have more $$$ to spend, replace the modify stuff with Prometheus and you're golden)

If the gears are busted:
Modify gear set (they come pre-shimmed and everything, just a drop in replacement)

If i forgot anything, someone please say so. It feels like i did, but i just cant think of what.

Yup that sounds like stripped gears or a stripped piston. [This was in reference to the video that used to be in the first post]

Your piston head could have come off your piston...

I had something like that happen to me before... and the gun was shooting alot like what yours is doing.

the gun just stop working after that but i can still hear clicking sounds
seems like the motor tries to turn

Take it back to that doctor to finish the job!

Or send it to me :D

It's what happened to one of mine.

75% its the problem.

I have same problem on my aksu! I need doctor in Newmarket area! Pls help:(
