I lubed it up a lot ( A LOT AND EVERYWHERE) BUT IT DIddnt do anything. the barrel or/and the spring guide/or something else is getting stuck or somethings blocking the path. i searched everywhere for anything.i have been working on this for an hour and i am really pissed off. please answer..please i need help. if u wanna ask a question just ask it and i might get a new yahoo acount so i can answer it so please help anyone just give suggestions. note i shot it when i first got the gun and then i took it apart. i used propane and the hop up is still thare and i followed the booklet thing instructtions to take it apart so please help

• Answer:

  well make sure the take down flap/notch whatever it's called is rotated 90 degrees clockwise because if you put it back to the original position it does not allow it to be put back together. That sounds like what you did. Also replace your spring. You can buy replacement TM springs on airsofting websites for about 10 dollars for a whole set for your springs. Well I need more information. Give me some pics and I may be able to assist you further.
