i never opend up my TM ak since i got it over a year ago except to put a tight bore in it. i have some shooting problems with it so thats what made me open it up and this is my question... i took out the gear box and took off the motor from it and i noticed alot of ,the best way to describe it, small shreads of somthing but when i rub it with my fingers it dosnt feel like shreads it feel like grease but it looks fiberous, theres alot of it right where the Pinion Gear meets the 1st gear in the box.. is it the gears grinding off or is it grease? should i take it all off? Not sure what it is cause my ics mp5 didnt have this when i opend that up..
