G&G M14 MAX won't fire
 

I bought a G&G BLACK M14 MAX there is one month ago. I shoted around 2000 bbs with it and it was fine. And now it just wont fire even with fully charged battery , and with mag or no mag. It just won't fire. I can hear a king of jamming noise but there is no bbs jamming in the barrel.I also had mag feeding issue. I How dont know how to solve the problem and i am wondering if i could fix it with out spending a lot of money

Thx for your help

Does the mechbox cycle?
Is it just not shooting BBs?
Is your hopup all the way on/off?
what brand and weight of ammo?
How often have you been cleaning your barrel?

The mechbox do not cycle and It is not shooting , with mag or not.When i pull the trigger there is a 'click' sound. My hopup is all the way off. I adjusted my hopup to all the way on or on middle and it still not shoting. I'm using KA 0.25g bbs. I cleaned my barrel once. Is it the battery the problem ? This is a 9.6v that comes with the airsoft.

Thx for your help

if the mechbox doesn't cycle, it has nothing to do with anything outside the mechbox
most likely you broke the back end off the piston and it's jamming the gears, you'll have to take it to a gunsmith and get it fixed, or open it up yourself

This problem happened 3 days ago then i charged the battery and i shoted 30bbs then it jammed again

That may not completely be the case. Have you charged your battery? That 'click' might just be the sound of the motor not being able to pull the piston back against the spring.

Charge your battery, or if you have another rifle, try saucing it in there and seeing if it fires.

That'll isolate your battery as either problem or not, and you can move onto the gearbox.

Edit: loljk you just said you charged the battery

My M14 is shoting at 475fps with .20bbs , does the spring is too strong to be pulled by the piston ? Should I put the M100 Replacement Spring that comes with it. My battery seems to be not normal , it lose a lot of charge. I will try my M14 with a friend's battery.

See if you jammed a part inside your gearbox. Is your motor getting hot when you try and fire? If so, that's a surefire indication that there is some form of mechanical blockage inside.

When i try to fire my battery becomes hot. But i dont know if my motor becomes hot.

Are you willing to open up the gearbox? If so, take a few pics and we can probably diagnose the issue quite quickly.

Otherwise, sending it off to a gun doc would be your best option.

I could try to open the gearbox.But i dont know how to

Then it's best not to.

Try finding a gun doc closest to your location and have them take a look, unless someone else here can offer some wisdom.

Ok , thanks for your advices , but i have a airsoft game tomorrow so i wont be able to play with my M14 :(

Oof, that sucks. Maybe a rental?

Find a different battery. If you're shooting 475 on the shitty G&G purple 9.6v I could see why it isn't working.

the battery that comes with it is garbage.. mine died after 2 months.

it could be more serious too, there could have been a compression jam and now your gear is out of sequence with your piston so it's jamming at the back of the gearbox.

Don't keep pulling the trigger, it might cost you a piston... the stock piston is not bad, but it will strip if you aren't careful.

Take it to someone who knows how to fix it if you're too afraid of taking it apart.

What kind of charger do you have?
It's been a while since the last "your battery isn't powerful enough" problem on here lol

I'm using the smart charger that comes with the battery ^^. It charges 500mah per hour.

Alright ! My M14 is working , my battery is dead. I tried my M14 with a friend's battery and it is working. The Airsoft store where i bought my m14 is going to give me a new battery :p
Thanks for your help guyz.

You should be using a large type battery with that gun anyway, since it can fit one.

Im using a 9.6v 1600mag small type battery , is it ok ? Also , could you send me a link where to buy a cheap large type battery.

Most airsoft stores will offer a plethora (of varying magnitudes) of batteries. Check to see if your local store has one; if not, a quick Google should help quite a bit.

As for your battery, if you feel it is enough, go for it. Small-Type batteries are simply known to last a bit less and have less power than large-type batteries (someone correct me if I'm wrong there) because of their larger capacities. mA is milliamps, h is hours, so mAh is Milliamp-hours. It's been calculated that the average AEG consumes ~1mAh per shot, but higher-strength springs like the one you likely have will consume power faster.

Someone is gonna let you play with a 475fps aeg?
And yes its a combo of crappy battery and charger and a way too heavy spring.

I'm playing with friends in a forest field. So there is no FPS limit. Is it safe for my gun if i keep my 475fps spring ?

I hope the field you're talking about is big enough. A backyard forest doesn't count. You wouldn't want a passing pedestrian or car getting hit because the field wasn't remote enough.

On topic, no, it is not good for the weapon. It requires a lot of strength to pull that spring, and unless you really know what you do and finetune the gearbox to withstand the stress, it will eventually fail. I'd recommend bringing it to 400 which is both safer for your friends and your gearbox.

I would like to keep my 475fps spring. Is the gearbox already enought strong to withstand the stress ? beacause it is the M14 MAX series.
It says :
The G&G M14 MAX Series features:
Full Metal Upper and Lower Receiver
Torque-Up Reinforced Gears
G&G High Torque Motor
Metal Ball Bearing Spring Guide
Reinforced Piston
High Compression Metal Piston Head
Reinforced Metal Cylinder Head
Low Resistance Silver Wiring
Tight Bore Barrel (6.04mm)

And if it is not strong enought , what i should upgrade ?

The piston will be the failure point.

i noticed mine had a hard time turning with the spring after i changed it my battery was fine idk....didnt feel like shooting someone with a rifle that was shooting 409......with .28's lol

The only thing "MAX" means is that's a marketing term that some Canadian distributor came up with after they crammed 470fps springs into G&G guns. It's no different than other G&G's.

Also, I am getting in some high quality large type batteries, cost is around $60-$70 depending on capacity, and they're worth it.

Give your rifle to your friend. Tell said friend to shoot you from 5-10 feet, in you arm, back, leg, stomach, knee, groin, etc...then a burst of full auto from knees up to shoulders.

I don't recommend head shots but I can't stop your friend from fully testing your rifle out on YOU!

If you come out without crying for mommy, and only the odd bleeder, I'd say you're good to go with 475fps.

Agreed. If you feel okay after being shot with it then it should be fine to shoot your friends with.

I hope this forest isnt just a random forest someplace and that it is on private property

wow , i'm not the bad guy with a 475fps gun hurting my friends , WE ALL use g&g MAX airsoft guns 450-475fps. And yes the forest is on a private property, this forest is huge. We don't shoot ourselves from 5 feet ! We are normaly shoting ourselves from 50 feet +. Also we are not kids ; we know how to play safe , we know our airsoft guns are not toys.

Also English is not my 1st language

meanwhile, you're the one asking if it's safe to keep your 475FPS spring?

if your first language is french, type in french. plenty here understand it, as most of us were forced to learn it in school, and the rest would use google translate. :)

i think he meant is ok for the gun to be shooting that hot ie. will it kill the internals shooting that hot......these things shoot waaay to fast out of the box....first thing i did with mine was get a new spring

False: they definitely have improved internals over the clearsoft versions. Not sure about the standard asia/USA version, I haven't seen one of those in years.

Also: Why do you guys care so much how he plays? The fact that he's here probably means he is in the top 20% of responsible airsofters.

+1
He's here with a gun problem guys, focus on that.

Alors , es-ce que c'est si néfaste que ça pour mon airsoft de garder mon spring a 475fps ? Si jamais le piston est briser es-ce que c'est cher Ã* remplacer ?
À quel FPS ça serait OK pour mon airsoft ?

And the clear versions were made specifically for the Canadian market. Therefore the "MAX" line is their regular guns with 470fps springs stuffed in them.

The only reason the name G&G still leaves a bad taste in some people's mouths are people are hesistant to buy them now is because of the clearsoft versions. Their actual lineup is awesome, especially the Toptech stuff, it's up there with the higher quality guns available.

J'ai déjÃ* répondu en Anglais, mais ma réponse reste la même. Avec la force que ca demande, tu ajoutes un stress énorme Ã* la gearbox. Le piston va assurément échouer un jour ou l'autre. C'est pas garantie que les autres pièces ne seront pas touchés aussi. Si le piston bloque en plein millieu, ce qui arrive souvent en tirant rapidement en semi auto, tu pourrais briser le moteur ou les connections électriques en forçant trop sur un spring très puissant déja compressé, par exemple.

Again, false. Every max branded gun i have ever worked on has had the top notch g&g internals. I have even compared the max branded guns to regular usa bought g&g guns and the max internals are better. This includes their ump, scar, m4, and m14 max and non max series of guns. Top tech are just max internals in a phneumatic blowback gearbox. Again have owned and compared both.

To the OP. Lesser spring and better battery. Done.

OK , thx all
Also my M14 shot at 475 fps with .20g but , im using 0.25g so it shot around 425 fps. Sorry for this stupid question , does when im using .25bbs it deals less stress on the gears ?

no same stress on internals. it is exerting the same amount of force as the mechanics do not change from shooting a .2g and a .25g BB. the end result is that the BB will exit the barrel with the same amount of energy but will be traveling at a different speed.

changing BB weight will not make make a difference.

they way I like to put it is, they will both still hurt, but one will hurt sooner than the other.

Ok , so what is the perfect FPS for my gears without losing a lot of performance ? I have a m100 replacement spring but this is only 325 fps.

Usually springs are rated by meters per second, so 100 mps is around 325. Which means that a m120 spring should bring you around 400fps. That is subject to variation is your airseal isn't perfect. You could get a m130 if you want to go over 400, but even that may be too hard, so I recommend the m120.

I'm too lazy to write in two languages, so English it is.

And one will be able to hurt at a further range as well because the lighter bb will shed energy and velocity alot faster then the heavy one.

I had a guarder sp110 in my g&g socom max and it was doing about 415-420 with .2s how's that for airseal? it was shooting beautifully, but just a hair too high for local fields since the limit is 400. That same spring in my other guns does 400-405 on a really good day.

The m100 that came in my box gets me 360ish with .2s on my gun, so I just ended up leaving it in there. Good enough as a loaner gun for folks who want to try playing.
