ICS M4 Help

[GreenBastard745]

Ok, got my m4 today, traded for paintball stuff, all went well until i decided to open it up.....i got the top half of the gearbox off looked at afew of the internals for awhile. Then put back togeather..now it wont fire, the motor and gears all go fine but it seems it wont pull the spring back, any help?
I dont know if its my stupidity or the gun, iam leaning towards my fault haha :P

Make sure the flat section of the gear is facing up.

If you did not press the forward assist (in this case spring release) before removing the receiver, the gears won't be in the right position and your gun won't fire since it's locked out.

Ok. So its probs locked out then..now what? Haha

Fire the gun in semi

Open up the receiver and move the gears back to the proper position. You shouldn't have to take apart anything other than the pins holding the receiver together.

Ok. It went back togeaather. But when I fire it makes like a bad sounding noise and cuts out?

[heikis]

did you open the upper gearbox? is the tappet plate in one piece (not broken)?

[GreenBastard745]

Dident open the upper gearbox, could i have busted it?

[GreenBastard745]

Nope its good, its weird, i mustve busted somethin when i opened it but i cant see anything, it seems like itll pull the spring back but not fire, cause after it loks and i open it the spribg will shoot forward

Something's not lined up right and binding when you close up the gearbox. Youtube some take down videos and have a look.

Hmmm, just took apart, appears i dont have stock parts bearing spring guide and piston with 7 metal teeth

Ohhh and a Turbo 3000

[GreenBastard745]

so anyways......dunno if i should open lower gearbox or not

dont wanna dick it more

Watch some video's about opening up ICS gearboxes and standard gearboxes in general before you attempt it. Its not opening it up that is hard, its putting it back together properly that can be a real bitch if you are inexperienced.
