If you are completely serious about upgrading "your" UTG MP5 then you should look at this. I am not sure if this would pertain to stealthmonkey's post (2 down) but here it goes. Credit to Airsoft Atlanta Blogspot.
Very interesting indeed. I guess the extra 0.5mm difference in the bushings and gears are to prevent any lawsuits from TM. But it would make an upgrade a PITA.
I found that a little while ago. I figure since I saw a post or two on here about "upgrading" the UTG MP5, why not post this. Just for those who are really curious (including me )
