V2 gear box break down?
 

the box itself is broken? it'll likely break after the first shot once reassembled, save up and buy a complete v2 box if that's the case, or just buy a real gun :D

mechbox.com would help. Other than that maybe make friends with a local gundoc and see if they can mentor you while you rebuild your gearbox.

The way it sounds the minimum you need to get is a new gearbox shell.

Something cheap like this:

clean everything of the old grease. then hop on over to mechbox.com and watch the v2 videos. hope you found all the pieces. lol

First of all, scrap the PDI 120% spring, it'll be a pain to install (likely), and it'll crack the front of your mechbox (a new reinforced mechbox, V2, can be had for $40) in a very short order. Don't know the fps you were hoping to get out of it, but get a Modify 90 spring from airsoftparts.com, it'll be easier to install, and make your mechbox happier too for longer. PDI has made crap inconsistant springs for the past years, I've dealt with a half dozen 150% springs, all ranged from 6 3/8" to 7", different metals and wire thicknesses, and have output between 350fps and 425fps. Go with Modify, and save yourself frustration and extra money to be spent for replacing more expensive parts.

A guide, lots out there, even videos, try youtube first, others here that are more familiar can link you with guides. I have a book for his, but also enough years with enough mechbox types and gun types under my belt that I don't need those references on my computer. I also know the inner workings on an intimate level, so it's easy for me to work my way around guns.

Best of luck, and enjoy your new puzzle!

hmmmm...... I know DamageInc does gundoc work however since the gearbox is in pieces (and you tried doing it yourself) the cost is probably going to be quite steep.

I guess fiddling around with it a bit more couldn't hurt (you got it a bit better fiddling around with it) however you might inadvertently break it even more.

This isn't even a V2 gearbox.

It's an all plastic gearbox with what looks to be plastic gears.

Don't upgrade this gun... Save up, new gun.

If you don't plan on playing any games anytime soon then u don't need this pos mpeg just save up and buy a real gun

Wow great advice pusangani.

He's already said he's not looking for that answer, he's looking for help to get his gun fixed. If you feel that this is an 'unfixable situation' than state so from your gundoctoring experience and suggest it's better left be.

Does it fire completely normally when held inverted? If so, it would sound like a magazine issue (mag spring not releasing the BB's)

If Amos is correct and this isn't even a V2 box but some random conjuration than buying any replacement parts is out of the question.(and if he says so I believe him, I've personally never experienced this gun)

After googling the gun and reading some reviews on it; if the mechbox is the same type of plastic I'm thinking of I think it'll be too brittle to last very long, sorry. (BTW, what kind of glue did you use?)

If you are looking to go to some more organized games in your areas, see if you can get in touch with guys and look into borrowing or renting until you can afford a new gun, I really think that'd be your best bet.

However, if this is just for backyard plinking, I hate to say it but I'm starting to think your pooched for now.

Best of luck!

Just to elaborate on the comment Amos made, the stunt studios M4 does not use a standard version 2 mechbox, it uses a smaller all plastic made mechbox which does not have the same dimensions of the standard V2.

Attempting to place an upgraded spring into the plastic mechbox will surely cause great stress on the already broken mechbox.

Options at this time are extremely limited, you cant even buy a new V2 mechbox and drop it in to the receiver due to the fact that the stunt studios body is smaller than that of a standard airsoft armalites.

wow, I didn't know it took years of gundoctoring experience to know how to use google properly :rolleyes:

Never said you needed years of gun doc experience to give advice. Just back up your statements by explaining them. Telling him why you suggest doing something willl do FAR more for helping him learn than saying "Your guns shit. Buy a new one". Especially considering he already admitted it wasn't the greatest gun, but for now was all he had.

Now if you had actually elaborated on why fixing it wouldn't work, than great. But as it was, that was a useless post, just like that last one.

This section of the board isn't for discussion or arrogant comments, it's for information.

And something to tinker with to learn the basic mechanics of an AEG with risking breaking something.

Bounces where in the chamber? Without seeing it firsthand, I'm not sure if I can help with this...

While he's right that this fps does seem to be the average in most new guns these days, you'd have gotten much longer life out of your gun if you had something like the modify M90, it wouldn't be so hard on your gun.

Ha, sounds like you made it stronger than it was before.

I'd hang onto that gun for now, and if you make it to a game before (and stilll want it working) see if there's a local gun doc who could at least look at it while you're there, give you some opinions. Although I'm not sure it'd be worth it to pay him to take it home and open it up (depending on his hourly rates I guess)

Sounds like the box is stronger than it was before :P.

Well I suppose theres a good chance that it is the same, hopefully the exact same. From what I recall on the topic I believe there could be issues with fitment with an actual metallic version 2 mechbox. However in airsoft as in life things do change, its more than possible that you could perform a straight out swap with little to no issues.
