Help! My gun is broke

After taking apart my Echo 1 Platinum M4 to upgrade the spring, I came across some problems with the reassembly, and now I can't get it back in working condition. Does anybody know how to reassembly a gearbox for a Echo1 M4, or does anybody know of a good repair company that will repair it?

Im sure it's like any other regular Version 2 gearbox. Don't send it away, it will come back in worse shape. If you let us know the symptoms we can be of better assistance in helping you. Most of us have jacked up a many of gearboxes.

Well, to start off.. Nothing was wrong with the gun, except I was getting 360FPS when I chronoed it last time, and I should be getting ~400FPS. I read on an Echo1 forum that upgrading the spring to a Madbull M120 will bump up the FPS. So, I took the gun apart all the way down to the gearbox and tried to put in the new spring. After it was clear that it didn't seem like it wanted to fit, I put the old spring back in. Meanwhile, all of the gears popped out, and I had to put them back into place. The tiny spring for the trigger and reverse lever thing is was took me forever to put back together. Finally just when I thought I had it all together, the negative lead that goes to the motor pops off, so now it won't even make a solid connection to the motor for it to work. On top of that, the gearbox casing has a crack in it from when I tried to put in the m120 spring.

So tell me... Am I screwed? I found a place in WI that can fix it for $30. $70, if I want the 1 year warranty.

put what ya got in a bag and bring it to the game .

I'm Sorry! I already packaged it up and sent it to that repair place. I'll definitely take you up on your offer the next time around. Hey, can I use one of those rental AEG's this Saturday?

next time bring it out to the field. between all of us you be amazed at what we can get fixed for ya

Bad move man. They're gonna charge you an arm and a leg and probably mess it up more than it was before. Don't be so hasty next time. We most likely could have got your gun fixed in less than an hour and had you shooting it the same day for the 17th.

yes i'll have one for you , and yes we could have fixed your gun i have spare parts even the gear box it self

I'm interested in what you paid? I do gun repair/upgrade at my shop in Panama City and try not to over charge. My rate is a straight $25 + parts. Thats for a basic rebuild to full upgrade. I check all components, airseal check, and will adjust fps to any personal designation. But I also offer, to anyone interested in working on their own stuff, to bring it to the shop and I'll teach you anything you want to know. I have no problem showing all the tricks and tips I've learned over the past few years. You do the work and I'll help with any hang ups you have along the way (no charge). Plus you can use my personal tools and see what is used to make the job a breeze. I've got several chronos on site, so everything I do is tested and proven to be what I say it is. In the past few months I've gotten a few AEG's that were worked on by repair guys, who installed a 120 spring and give it back only to have the gun shooting below 120fps. Not cool!!!

so nice

thats awesome mack.
