two_zero Posted December 24, 2012 Share Posted December 24, 2012 In theory, I dont even mind this.. however, now the gearbox locked as it sometimes will do at semi.. the normal solution is to go onto auto and fire and bam you're ready to go.. obbiously I cannot do that now... so well, why does the full auto not work and how do I fix it? It a metal TM m4 (colt 733 commando) btw. Link to comment Share on other sites More sharing options...
Supporters Airsoft-Ed Posted December 25, 2012 Supporters Share Posted December 25, 2012 More often than not the opposite occurs and you're stuck with no semi auto, which happens because a part wears out, of which I forget the name... I imagine for you it'll just be something to do with the selector plate, which is external to the gearbox and is what the fire selector lever moves when you turn it, in order to change the fire mode. There's a similar problem with the M4 I'm selling. The selector plate on mine has slipped slightly, so when you switch to auto it still fires semi for the first shot, then auto afterwards because the selector lever doesn't move the selector plate far enough to properly engage auto. In short, you need to get the gearbox out and correct the seating position of the selector plate, a spring might've potentially fallen out of it as well. It doesn't require gearbox disassembly, just to take the gearbox out of the gun and all the parts you need to fiddle with are external. In all likelihood, simply taking the gearbox out, giving it a once over and putting it back in will probably sort it out, you probably won't even need to really do anything. Ought to be an easy enough fix. Good luck. Oh, and Merry Christmas Link to comment Share on other sites More sharing options...
two_zero Posted December 25, 2012 Author Share Posted December 25, 2012 hmn.. can only slide the top receiver half the way off for some reason.. tried wiggelin and everythin! systema gearbox btw if it makes any difference? Link to comment Share on other sites More sharing options...
two_zero Posted December 27, 2012 Author Share Posted December 27, 2012 bump.. anyone got any idea why I cant split it fully? Link to comment Share on other sites More sharing options...
Supporters M_P Posted December 27, 2012 Supporters Share Posted December 27, 2012 is it wired to the front and getting caught on the connector? Seems obvious but you never know Link to comment Share on other sites More sharing options...
Hudson Posted December 27, 2012 Share Posted December 27, 2012 Is the charging handle catching on the little nubs on the top of the gearbox? Try opening it and pulling the handle back. Link to comment Share on other sites More sharing options...
two_zero Posted December 29, 2012 Author Share Posted December 29, 2012 Neither I'm afraid. It is back wired and I pulled the charging handles and wiggled. Though a pic is better way to explain how far I can remove it. it looks like its the bolt release that prevents it, but it seems not to, it wiggles up n down a few millimeters..

Supporters M_P Posted December 29, 2012 Supporters Share Posted December 29, 2012 Does the hop leave the air nozzle ok? Love the lower receiver by the way Link to comment Share on other sites More sharing options...
RR01 Posted December 29, 2012 Share Posted December 29, 2012 With the upper as far forward as it will go, turn it over and look into the magwell. Can you still see the hop unit? If so, it's possibly that which is stopping it moving, as it should slide forward with the upper, not stay put. Otherwise, if the hop has moved, shine a torch in there to see if anything else is catching, as that may well be why you have a problem with it.

Supporters M_P Posted December 29, 2012 Supporters Share Posted December 29, 2012 How hard have you pulled it? It may just be the the gb is a little too wide for the receiver? Obviously don't rip it apart but yaknow what I mean Link to comment Share on other sites More sharing options...
geoffreym Posted December 29, 2012 Share Posted December 29, 2012 I've got the same body kit, only way I've been able to disassemble it is to take it apart bottom up, e.g remove the grip and motor, then take off the lower half, and then for some reason it frees up the top half, no idea what releases it. (just to prove I have one "https://plus.google.com/u/0/photos/102321626070351311138/albums/5575836519120718321") Link to comment Share on other sites More sharing options...

Hudson Posted December 29, 2012 Share Posted December 29, 2012 *Definitely* not the cocking handle then? I only ask; as when I take mine apart it gets exactly that far before getting caught on the top of the gearbox casing, pulling the cocking handle back about half an inch or so frees it up. Otherwise; no idea...Seems strange. :/ Link to comment Share on other sites More sharing options...

Otherwise; no idea...Seems strange. :/ *Definitely* not the cocking handle. Sure it was exactly this far? Just a few cm before that the cocking handle IS in the way and needs to be pulled to allow it to go further. Anyhow, seems a solution has been found!

(just to prove I have one "https://plus.google....36519120718321") *nods* was almost guessing this. I think I found the problem, it is that there is a "rail" on the ejecting side on the top receiver that wont come off. And yes, only solution, except for some mad dremel destruction would be just that... well, good thing I wanted to get the gearbox out of the lower anyway.. What make is the receiver? I would also like to know. Link to comment Share on other sites More sharing options...
geoffreym Posted December 29, 2012 Share Posted December 29, 2012 I might end up dremeling it then, and regarding the make, zeroone are the only people i can find who do them and i couldn't (beginning of 2010) get them to tell me what make they are, or if they are an own brand.

two_zero Posted December 29, 2012 Author Share Posted December 29, 2012 I might end up dremeling it then ...do that on your own responsibility and find out if the rail serves a purpose first. I wouldn't touch it. Link to comment Share on other sites More sharing options...

RR01 Posted December 29, 2012 Share Posted December 29, 2012 OK, just a thought, but have you tried pulling it forward with the ejection port cover open? If it's one of those that has the false cylinder cover in the top part as well, it may be that which is catching on the edge of the front of the gearbox. If it is one like that, try putting a small screwdriver inside the false cylinder at the front to ease it closer to the side of the receiver and see if that works.

two_zero Posted December 30, 2012 Author Share Posted December 30, 2012 Again, there is a "rail" on the inside making it impossible to move it any other way than up. Link to comment Share on other sites More sharing options...

(just to prove I have one "https://plus.google....36519120718321") motor, grip, magcatch, all romoved, but the upper wont come off and the gearbox wont come out of the lower:( nm, got it out, will prob demel the upper. will built it back up and see if its fixed!

two_zero Posted January 19, 2013 Author Share Posted January 19, 2013 taken it all down and put it together again. everything looks fine, the gearbox works on fullauto when I stick to motor straight into it. So I kept pulling the trigger on full auto at each stage. put the stocktube on. works fine. grib, works fine. motor, works fine. but then when I plug in the cables and the battery, I cannot press the trigger in any more, flip to semi, works. So the trigger wont even be pulled in fully on auto. any ideas? it all looks like its in fairly good condition! Link to comment Share on other sites More sharing options...

geoffreym Posted January 22, 2013 Share Posted January 22, 2013 is the gun front-wired or rear-wired through the mechbox, and how are you mounting the battery? did you do the wiring yourself? can you see any physical obstructions from looking inside through the bottom of the trigger? I'm assuming you don't have any mosfet? is the selector plate damaged? (my rifle once refused to go onto safe because it was cracked) Link to comment Share on other sites More sharing options...
two_zero Posted January 22, 2013 Author Share Posted January 22, 2013 I did not wire it myself, its back wired, and the battery I keep in a pouch on the stock. nothing looks cracked, and I can go into full auto on the selector, just no compress the trigger. aha! took some photos and noticed the selector plate is damages, a lil crack in the upper of the arch that makes it bend a bit, think that will be the cause?
