Yep me too. I also put a homemade very nice mosfet into my AK M249 - so far so good. it was a little bit of a hassle with all the wires, but nothing more then it was on a regular ics m16.
Stock config, running on 2200mah 9.6V NICD battery, about 1k rounds, 2 first teeth from the sector gear snapped off from the bottom and due to that the hole piston shred in a few rounds or so. replaced the sector gear with G&P that was lying around and put a TM stock piston in. ATM have gone about 2k through, with ICS stock spring that gives 96m/s with 0.2g bb-s measured. Going good atm.

My fresh SL9 should be just over 1k i guess.

All the internals, spring is just a bit too much to discuss here, 2k mah battery etc..
Was it just me or you didnt mention anything about shooting it? Really would like to knoow about he fps and its consistency also the hopup and its reliability. Cheers.
