i have the GJ M4 s-system, however after owning (and loving it!) for about 3 months, every time i try to fire it, it doesnt fire for a few trigger pulls then 2 or 3 BBs come out of the barrel at greatly reduced velocity. i take the magazine off and there’s always 1 BB left when i dry fire it. HELP!!!
Try to bring your aeg to your airsoft gunsmith. Your “hop-up rubber” might be worn out by now and needs to be replace. You may opt to insert a “sector chip” in your “sector gear” to eliminate misfeeds on your aeg.
worn out after 3 months??????????
That depends monty. Assuming you have a good piston/cylinder compression. We can point out that the problem is within your hop assembly. There are many instances when your hop rubber easily worns out. One problem with china-made AEG’s such as Jing Gong (JG)/A&K etc, their quality is not as good as the Japan or Taiwan made AEG’s (TM/Classic Army/ICS). If you have been playing airsoft 3 or 4 times a week for the past 3 months, your “stock” hop rubber may easily worn out. Try to check your hopup rubber to see if there are cuts around the lip. You may try changing it to Systema or Guarder brands. If you think its not your hopup rubber thats making your aeg misfeed, you may try to insert a sector chip in your sector gear and see if it eliminates the problem. We usually troubleshoot AEG’s by using the process of “elimination”. In that way, we can easily pinpoint the problem.
it appears that, without upgrading the jg m4 system internals, by using lipoly 11.1v it will reach to 410-430 fps, and it will not shortened the life span of the stocks or cause damage on it? is that possible sir?
The new JG units comes out with “plastic” and not the metal bushings, using lipoly increases the rate of fire (ROF) of the gun and you will be putting increased pressure and strain on your gears. This is why it is imperative to replace your stock gears and bushings with high strength steel gears(optional) and metal bushings.
one thing sir, on your opinion and base on your own experience,if you to uprgade a jg m4 s-stem out of the box that will garnered an 440-460 plus fps,what parts do you suggest to install on it to reach the said rate? the cheaper one,but durable and reliable, i openly appreciate your opinion on this sir and tnx.
PDI 190 Spring, Guarder Version 2 Spring Guide, Techpro Metal Bushings. Please remember that upgrading your AEG to have higher FPS is like going to the Dark Side of the Force. It is very alluring and sexy and a seemingly easy path to more kills. Upgraded AEG’s require more maintenance, are less reliable and more prone to catastrophic breakages. Often to change one part you need to change 5 others. Once you go down the path of of the Dark Side, the costs increase exponentially. Remember, it’s not the FPS of the AEG but the quality of the player that gets kills. May the Force be with you.
gave it a good boogie (clean) and it started working, played for about an hour last nite, no problems at all! thinking of changing the hop up rubber anyway. cheers for the advice
i bought an M4 Carbine just last week and did alot of test firing lately. Being a newbie to the sport, im scheduled to join my first war game next week, hopefully it will be a weekend thing for me from then on. How long will my JG M4 Carbine last using the stock parts if i normally play on a regular weekly basis? i agree on what you said that it is not the FPS of the AEG that counts but the quality of the player. Do you recommend that i keep my AEG “stock” forever if i have to replace worn out parts eventually?
Your AEG may last long using stock setup and proper care, but remember that JG do only use plastic bushings which you have to replace in a month or two.
the accuracy of my s-system is a bit… inconsistent…. to say the least. is this just because of the ‘cheap and nastiness’ of JG AEGs or is it something else. and would buying a precision barrel help at all?
many thanks
Buying precision barrel would really help the aegs accurancy. Try Prometheus 6.03 Barrel.
Based on the comments and suggestions you made on this forum, can you give me a ball park figure on how much will it cost to upgrade a JG M4 Carbine if ever i decide to do so? eg. metal gears, metal bushing, 11.1V batt, springs??.. will the upgrade amount to more than the actual cost of a stock JG? I bought mine for P4,500. Thank you sir!\
Est. Upgrade - Metal Bushings P500, Spring guide P900, PDI Spring P700, Lipoly bat P1,800.
roger copy! tnx good buddy!
Im thinking of getting an s-system. What would you say is better the d-boys one, the a&k one or the Jing Gong one?
To tell you honestly, I was not able to check the new DBOYS AEGs yet. I have tried the JG and A&K S-Sytems and I’m leaning towards the JG (2008 version) on this one.
Ah kl, thanks man i was leaning towards the JG too but the abs body was giving me 2nd thoughts. Il probs get the JG now n jus downgrade the spring, its too hot for uk airsoft sites
lol
Yes, the ABS body… if you want your external to remain stock then JG is for you. But if you want to upgrade to a metal body it will be hard since JG S-System has a Clam Type Upper Reciever which is very hard to find and if you do find some its expensive.
what is the cheap and reliable lipoly battery charger/balancer available in local market?
Hmmm… i’ve been using the Esky 2-3 cells Lipo Li-Po Battery Charger (7.4v 11.1v)$7-10. So far I have no problems with it
Should i buy the the JG M4A1 just because of its velocity or should i go with the durability of a classic army and buy the sportlne M15 A4?
Hello Paul. That depends on your choice. The cheaper Chinese made AEG’s are new to the market and do not have the consistency in fit and finish than the older and more expensive Japanese/Taiwanese counterparts. But, this line is constantly becoming fainter between the three as the Chinese continue to better there manufacturing. In my own opinion, I say a “stock” Jing Gong M4A1 is better than the “stock” Classic Army M15A4 Sportline…. BUT, a well “upgraded” CA Sportline M15A4 is better than the “upgraded” JGM4A1.
I am going to purchase this gun with the A&K 5000 round drum and i was wondering what extra battery i should purchase with the gun. i must mention i have no means in spending money on an internal upgrade.
You gotta use a battery with high “mah”. But you gotta change that “bushings” if you’re gonna use a round drum.
using esky 2-3 cells lipo Li-po Battery Charger (7.4v-11.1v) is it ok even for 1500mah? i really appreciate ur comment sir,tnx
Yes, it is fine to charge an 11.1v, 1500mah with an esky 2-3 Lipo Battery Charger/Balancer. But please bear in mind that Esky Charges only up to 1000mah. So this means that you will still be able to use your battery but, you will not be able to get the maximum performance of the battery.
well .. i just oredered the jg m4 s system enhanced version from airsoftgi……..u think is a reliable weapon?……in other words, is it good ?
perfect choice, tiko
may i kow how much JG m4 s system cost in manila and where could i find it…
Prices now for Jing m4A1 ranges from 5.5k to 6k. You may find some dealers at filairsoft.com
i was given a 9.6v 1100mah battery and i have a jg m4a1..if i use it instead of the stock 8.4v battery will my internals last long? will changing the stock bushings to metal bushings enough?
Your internals will last long as expected if you use the stock 8.4v battery. Though we recommend later on to change still your plastic bushings to metal
Mate, you seem quite knowledgeable so maybe you can help me. I will be getting some of these 2008 JG M4 as soon as airsoft is legalized in Australia (december 200
and i want to downgrade the spring in the JG guns to be on par with tokyo marui, about 280-300 FPS.
I will use a guarder m85 spring, however do you know of any article, document, manual/e-book, or gunsmith forum where i can get a how-to on installing the new downgraded spring? I will be getting about 20 of the JG M4 as i will be opening a small shop and playing field, i need to learn how to be a gunsmith! Thanks mate, have a good one.
Hello mate, you might wanna check these troubleshooting videos about dismantling and assembling your airsoft gun. Click HERE.
Here is a link for AEG Spring Comparison
And an article on how to properly shim your gears
Hope this helps. Goodluck!
thanks mate, i’ll have a look at those and become a pro gunsmith lol. thanks for your time!
sir.. wr can i find som1 who could engraved serial number on my EAG. kuha kasi ako ng permit dito cdo?
I don’t have any idea sir, but we plan to have our guns engrave by our own selves.
greetings sir, just wana ask some opinion regarding which is a best buy… talking about over all performance… a JG M4 M733 or an A&K M4 M933? Thanks…

Hi Airsoft enthusiasts, i bought a second hand stock M4-CQB, its a month old when i bought it.. have a problem regarding misfires and often have slow firing BB’s. ive brought this to a specialist already, he placed a sector chip, and a hop up rubber. still the problem persist. any suggestions that might be helpfull? i would greatly appreciate it.. thank you
Try to clean your inner barrel with silicon spray. Some similar problems points to a defective magazine, try a different magazine and seal all “air-leaks”. Hope this helps
Thanks for the Quick response, il check on it as soon as possible.. T.Y.
sir if there is an air leak in the aeg, what is possible parts should be replaced or be repair? thank you sir.
This is an article from Warthog of Filipino Airsoft, you may want to check this out.
sir..nagsettle na po sa 380 fps ang jg m4a1 ko..balak ko lang pong palitan ng tight barrel, siguro yung 6.03 lang..ilang fps po ang maidadagdag nya?..at isa pa po..di-ne-cock ko yung m4 ko tapos ginawa ko yung ilawan ng flashlight sa pinapasukan ng bb at sinilip ko yung barrel..may ilaw sya eh..it means po ba na may leak aeg ko or may mali akong ginawa(hindi ko kasi alam kung papaano ipasok ang nozzle sa hopup eh..)? maraming salamat..
adding tight bore barrels may add-up distance to your range (around 10-20ft more). With regards to assembly and disassembly of inner barrel hop-up you may check this video for reference. http://youtube.com/watch?v=qai5sf76z-k
IT IS A BIG HELP. THANK YOU VERY SA SULAT MGA BOSING, GOD BLESS, ALLAHU AKBAR.
hi sir, I just bought a JG M4A1. About how many years do think it will last if i play a couple times a month and keep the stock internals and etc? Also should I buy a smart charger to help the battery last longer or are they just a waste of money?
Thanks in advance,
Adam
If you want your JG M4A1 to last long, you may want to change that plastic bushings to metal. I cannot guarantee that your aeg will last a year if you won’t change those bushings. Those stock springs needs to be changed too. After 5-10 games, the gun velocity would degrade by 20-30fps. So I would suggest to upgrade that aeg later on. Smart Chargers are good to your battery especially you are using NiCad, NiMh or Lipolies.
hello. gud pm.
Im newbie in this sport. what scope can you suggest to my m4 cqbr?
another thing, what part of my m4 will first worn out and any suggestion for quality and upgraded replacement it?
You might want to check some EOTECH or ACOG scopes. If you’re using Jing Gong brands, then you may change your plastic bushings to metal.
thanx.. a lot.
i just got the m4 cqb and i dont know how to put the battery in can anyone tell me!!!!!!!!!!!!!!!!!!!!!!!!!!
To insert a battery into a m4 cqb, you need to remove the rubber butt plate at the end of the stock, then push on two cheap plastic tabs to remove the back portion of the stock. There is a battery connector in the main tube and tubes to either side to insert the nunchuck shaped battery. Hope this help.
good day sir..which do you think is better? an m4 length tight barrel or a longer tight barrel in which the excess will be hidden inside a suppressor? i have a stock jg m4a1? and last thing, does the jg hk416 have a better spring than the jg m4a1 ver.2? thank you sir..
Q1: Which do you think is better? an m4 length tight barrel or a longer tight barrel in which the excess will be hidden inside a suppressor? Ans: The longer tight barrel would give you more distance than the standard tight barrel
Q2: Does the jg hk416 have a better spring than the jg m4a1 ver.2? Ans: Both are the same. But there are some instances the hk416 exceeds the fps power of the m4A1.
i just bought a jg m4 cqb 2008, the box says its 330
but by itself how far does it really go, and what upgrades should i buy for it and where can i get them.
Some countries have restriction when it comes to airsoft FPS. Some countries or states in Europe and the US limits their FPS to 360-390 fps only. As for the Philippines, we can go as high as 500 plus fps. If you want to upgrade your AEG, pls check your country’s restriction. You may visit rsov.com for your upgrade needs.
hi mate was just wondering what RIS handguard would fit in the M4A1 ? I recently bought a Dboys RIS handguard kit but it doesnt fit :S
What brand of M4A1 do you have? Make sure that if you buy external upgrade parts for your AEG it should be of the same brand. Ex. JingGong M4A1 should be installed with JG RIS upgrade.
good day sir..i installed a spring guide with bearing in my jg m4a1 together with a jg hk416 stock spring(it is longer than the jg m4 spring)..after a 600rounds of bb’s..it made a whirring sound and it seems that the piston body’s teeth broke..i opened the gear box and i was right..is there something wrong in the way i assembled my gear box? is there a proper way of aligning the gears when you put them back up? thank you sir..
You have to shim your gears properly. Check this page.
Hi I just received my JG M4A1. When I shoot the gun the bb’s fly way up and I adjust the hop up correctly and they still fly up. I switched to .25 bb’s and it didnt help much. Please help me. Thanks.
Check your barrel first if it is clean (Use silicon spray to remove bb residues). Check your hop-up bucking and replace it if there are any damage/cut around the lip. Check also the hop-up spacer (small rubber) if it is properly installed (straight and not side-ways). Hope this helps.
gUBA NA AKOA .oke pa dynamo pro ungot mga gear
can i upgrade the internal parts of my jg m4 s-system using other airsoft brands??, which brands can i use to upgrade it other than jg parts
You can use systema, guarder, techpro or ca brands as long as it is version 2 parts.
Sir:
Gud Pm. I am planning to change my bushing to metal bearing however I am not sure whats the size(mm). I would like to solicit your idea f what size, mine is JG M4CQB with version 2 mechbox. Thanks.
6mm bushings
Thanx sir.
sir i have a query regarding JG M4 S System…is the stock bushing of this unit already a metal bushing???? and what is the best upgrade for it…thanks in advance!!!
The latest JG M4 S System are with metal bushings. You just have to upgrade the spring guide if you wanna increase its spring.
gud day..would a pdi190 break my stock piston body? what about sp120/m120 or sp130/m130?..thank you..
I’m using PDI 190 with stock pistons. So far so good. The higher the spring, the higher the risk.
Hi,
just wondering about the new 2008 JG M4 CQB, is the stock bushing also already a metal bushing ?
thank you
The JG M4a1 2008 version has metal bushings. It should be with their CQB.
hello’
is JG gearbox or other gearbox compatible with ICS m4(the one with modular gearbox)?
TY<
ICS Gearbox are “split-gearbox” therefore not compatible with JG version 2 gearbox.
is JG or other brands of v2 gearbox compatible with an ICS M4 with a modular gearbox(the split type)?
ICS Gearbox are “split-gearbox” therefore not compatible with JG version 2 gearbox.
