changeing springs?
 

Hello everyone, i need some help puting a new spring into my tm m4 (new version) if anyone has done this and knows how... can you please inform me on how to do it please and thank you

I use this and it works great for me.

Just make sure you take it slow when you take the gearbox apart. don't let things shoot around. Read through the guide before you start, then start and do it step by step.

After doing it, I think it's something anyone could do. I've never had a problem.

keeping in mind, even with a guide, Id say about 1/3 of the people who ask, come back here looking for a gun doctor because they screwed it up.

gewiz, it looks like im gona get somene ells to do this for me haha, cause i know i will map all the screws and everything, get it back together and something will be wrong :( thanks anyways for the information guys

Honestly, and no offense meant, that is why it's strongly suggested to find someone with experience and watch it being done the first time.
