lolz. omfgbbq.

I've researched airsoft guns EXTENSIVELY. I like the data, but there are things I'd like to know from experienced JG M4 S-System users. Thankz guyz............ What size batteries should I go with? The JG uses small types.

yes so get a small... just get one with 2000+ mah for that guns massively strong spring.

The 1100's not good enough? What kind of spring do they have? M130?

i think it's like m110-120 but the whole combo of evrything in the gun requires a stronger battery to get a good rof & battery life

I see. Does the TM or CA m4's, m16's, AR15's use 2000+?

they have weaker stock springs and don't come with batteries, so what ever they use is what ever the owner has/buys for it. They need stronger batteries too though when you upgrade them.

Will a 2000 be enough for future upgrades?

well if your gonna game with it DO NOT upgrade the spring, some games it will already be too strong, I'm getting a JG too and I'm putting a weaker spring in it so in other words... a 2000 mah SHOULD be good enough (IMO) for most future upgrades though there may be some upgrades which require more battery strength that I am not aware of.

Is changing the spring relatively simple? Could I change one at field if I failed the chrono?

I would say no, not with a conventional V2 mechbox, an ICS like mechbox that splits you cold but not with a JG, you have to disassemble the gun, take out the mechbox, open it and replace the spring... It's not too hard really if you have the manual and are very carefull to rember where everything goes. First time might take you like 3-4 hours to put it back together though... Might just wanna contact a gun tech in your area and get him/her to do it for you.

Well, I live in Windsor, and will most likely be playin outta town...(hopefully FR outdoors )

well find out what their FPS limits are and if your guns too hot then you should try to find a gun tech to change the spring for you I'm sure if you post on one of their game threads that you might want to attend that you need to find a gun tech before you can play then you might find one that way.

Thanks man. Any quality issues anyone knows about, hit me up.

google Click it is your friend. USE IT.

FPS limits at FR are 400 AEG and 450 Bolt Action
most indoor is caped at 350 all around
I have a JG M4 and I put on a CAVS so now its like an S system and the JG has been great for me so far without any problems even the stock mini last all day in the summer however you mileage may vary as some folks are BB hoses

Mini's don't come in 2000 mAh.

I use 8.4V 1500 mAh mini's with my M120 spring, and they work fine.

Stock the JG should be bang on FPS wise for outdoor. Just buy a couple of batteries. It all depends on how heavy you are on the trigger too. I ran my m249 on 1500 mah mini's, just needed to change the battery a few times cause I was hoseing al day.

cheapbatterypacks.com I bought mine from there the elite cells work great.

I own four JG ,s and think they are all great!

love the jgs just lack of trades great gun for building up though

Agreed!

Thanks guys. What spring/battery can I use to put me just under 350? Thanks

Amazing what a little searching will do :rolleyes:

Someone has PM'd my answer. Probably wasn't that hard either.

I had an S-system, and it never worked right, I redid the gearbox a few times to no avail. The only thing I never did was change the spring out.

I used 1100mah packs on all my oher guns, but they wouldn't fire the S-system. It would stick and bind half way back, and it would never work on semi, only full auto at about 2 bb's per second on a full battery, warm or cold.

Get a smaller spring in the M100 range and be safe, you'll pick up some rate of fire, alot actually. Velocity isn't everything, the gun has a long barrel and it's going to be accurate no matter what.

Bummer about it is that it has no room for a battery any bigger than a mini 8.4v. If later on down the road you want a larger output battery, you'll have to buy a decoy LAM to install your 9.6 packs into. 9.6's will be just fine in the stock JG if you choose this route.

Thats why I prefer regular M4's now if I want armalite, more room in the forward grip for bigger batteries.

I'm on an HK kick now, love my TSD MP5A5. :D

Have fun with the gun!

You could also go for a battery crane stock, if you like the look (I find them a lot more comfortable as well), and don't mind rewiring it to the rear.

yeah the crane stock is just taking advantage of the fact that the RS M4s have better more comfortable cheek piece stock that coincidentally could fit a battery

And your point is?

Thanks guys...I've been chatting and I found a better gun for my needs.

The JG HK416. Crane stock. Droppin in a Systema 1 spring. Putting a 9.6 3800 or 4200 in the crane.

I think I'm going to get a KWA olive and black USP .45 GBB as well.

That's something of an overkill for a 1J spring.

For how much it cost's, isn't it worth it for the guaranteed life?

Higher battery power does not equal more guaranteed life. In fact, using a battery that's too powerful for the gun shortens its life. You should be looking at a 8.4v battery instead.

Is the 9.6 ROF worth the lower life? What size 8.4? 3800 or 4200? Thanks

8.4v would give you plenty high ROF. You're not "sacrificing" ROF by avoiding 9.6v, you're avoiding a silly ROF.

For NiMH batteries, anything between 1800 to 3800 is enough for such a modest spring.

Is the Systema 1 the only way to get a JG HK416 <350 fps?

Plenty of springs are rated for 350fps or less.

Knowledge leecher ! :D

Sorry. Is a different spring the only way to get under 350?

Okay, everybody just settle the hell down for a minute & stop talking about swapping out this spring for that spring & so on.

I took my new JG/Echo M4S to it's first outdoor game today & it smoked a lot of players.
Lots of comments & questions about it & a lot of surprised looks when they discovered what it was.

Now, the only thing I did, more out of frustration than anything else, was mount a PEQ battery box to the right side rail to incorporate a butterfly 9.6V x 1700 MaH battery - THAT"S IT!!

That's all!

You don't need to start swapping this that or the other thing - know why?

No, why, Uncle Haggis?

Because the JG M4S comes pre-tuned.

Really!?

Yes, really.

Case in point, my AEG has a factory installed tight bore (I checked upon arrival) & the new black systema clone mech box. (that's right kids, no shit.) that chronos at/around 410/425 FPS with .20's.

I haven't chroned this gun yet, BUT!! I was knocking down players at ranges exceeding my other riced guns using .25s. these weren't lobs, these were direct engagements of opposing players.

I was able to engage through dense pine boughs & heavy foliage & make hard & direct contact hits on other players. (They were damned surprised to have that happen!)

So relax - research a little more & understand that you don't have to immediately spend more money gutting a perfectly good little clone right out of the box.

Now, if you're concerned about a lower fps rating for different fields I suggest, & that's all I'm doing here, suggesting, you try a different make & model. You'd be doing yourself a real disservice of gutting the current JG V2 M4S system AEG. I was shocked, as were other players, of how hard it shot & how hard it hit at some pretty damn impressive ranges. Find a used TM or ICS for lower base fps limits.

Myself, this is my 3rd Jing Gong & I see their product as only getting better.

My 1st, a JG M16A4 shooting 380+ fps straight out of the box.

My 2nd, a JG M773 shooting 380+ fps straight out of the box.

But! My new JG M4S blows both of them right the hell outta of the water & all I did was incorporate a larger battery because I hate fighting to make that shitty little 8.4v fit under the barrel.

Merely an observation of past posts, a few suggestions & some opinions.

...here endeth the rant.

I like how I can change back to the stock spring when I want. Workin on guns is cool. For the price of my JG HK416, it seams like a great gun. Does the HK416 have the Systema clone as well? Or the TM clone?

http://www.airsoftcanada.com/SpringChart.html

find a big list and the approtimately the fps it will shoot, in ur gun it may shoot faster or slower, but this is to give u an ideal fps it will shoot

I was just wondering if there was an alternative to changing the spring. Thanks

nope ultimately, changing the spring is the easiest, cheapest way to lower the fps

Hey, Haggis, look like you got 2 more posts for nothing here. You can't help them if they don't help themself. Sorry about time you have lost.

You're apologizing to someone who, by all means, was not personally forced, required, contacted, or otherwise solicited to help me at all?

You indeed are the one who's time was wasted by replying for 3 reasons

a) see above

b) it offers no new or pertinent information relating to original thread

c) This reply will lead you to post again wasting more of your time

Thanks

Aside from your blatent disregard to what people have said on here, I'll try anyway. Maybe I'm in a good mood thismorning.

What Haggis is saying is that the JG M4S is very well tuned, from the factory, to perform as it does out of the box, and hence swapping out the spring will really hurt a really great performer. He suggests, if you want a lower FPS, purchase a gun with a lower initial FPS.

Now, you mentioned that you have no issue swapping springs and that it's easy. Well, yes, you are correct, but keep something in mind: Every single time you open the mechbox, you lower its durability. The first time it's opened, its durability goes WAY down, and every time thereafter. As a rule of thumb, avoide opening the mechbox unless you have to, especially if you're new (this isn't a slight on you or anything, it's just people who are new to AEGs don't always know how to spot signs of wear and early failure in a mechbox, etc. so they are better leaving them be until they learn more about them).

Now about the battery. If you want the battery to last (IE, long gaming time), you want to look at the millaps (mah), not the voltage. Voltage effects rate of fire, milliamps effects play time. 8.4v gives a respectable ROF... usually around the 12-15 rounds per second range, depending on the gun. Honestly, you don't really need any higher than that. So get yourself a good 8.4v battery (if it's a mini, go for 1500mah, if a large, anything above 2000mah should be fine).

There are options beyond the systema 1 joule for a spring. I prefer the guarder line of springs myself. The guarder sp90 is a decent spring and would give you something in the area under 350. Like someone else stated, a larger battery isnt always a good thing. Having to large a battery with to much juice and to weak a spring could possibly cause alot more wear and tear on the internals due to such a high speed.

Heres a another link to a list of springs, the first chart is what you should be looking at for under 350.

Like haggis linked earlier, here is a link to the JG HK 416 review, which is actually writen by myself. http://www.airsoftcanada.com/showthread.php?t=50930

I do believe the 416 reviewed in the review is a generation two in the 416 series. Systema clone mechbox, 417 style stock, well you get the idea, all the info in the review.

Well there's always the TM Velocity Reducer, which is easier, probably not cheaper, and I don't know how well it works.

Thanks for helping ( TokyoSeven & Styrak & kalnaren ). I read your review. Helped alot. I think you should edit your original post to include the latest mechbox info. It was a bitch looking through all those posts...lol JK.

A 8.4 4200mah would work just fine for me eh? Thanks again guys

just buy a couple of springs 1 for FR outdoors and 1 for Windsors feild...im sure someone in windsor will show you how to do it...

The JG HK416 stock spirng shoots around 400 so I should be alright for FR.

wow dont mess with the jg internals they are very well made. iv had problems with them once i got it if yours shoots dont take it arpart leave it be. just get the tm volicety reducer form ehobby 22 bucks shipped to you

Thanks, I'll check it out.

thats what i do i have mine fireinf just under 400 stock the new black mechbox and now when i go to indoor its used with a tm volivty reducer hope thats the right spelling. im a nub and wouldnt ever want to take apart that thing hard shit to get right

I just got my JG M4 S-SYSTEM .. i love it but was dissopointed to see my battery does not fit , there is no where to tuck away the stiff battery cords without messing up the placement of the battery , basically i just cannot close foregrip at all due to this , making my gun useless until i find a solution . Tips welcomed..

Thanks guys for your help. I have now confirmed payment of my JG HK416. I chose that because of the battery (crane stock), trades, and the reviews I've seen. I paid $185, but we won't talk about that. The M4 was my first choice, but the HK416 made more sense in the big picture. Thanks

Find & mount a ANPEQ battery box to the right, or left side rail. This will incorporate your 8.4v mini bat, or better yet, a 9.6v mini bat or butterfly type battery.

Problem solved

Like this example, for instance...

http://www.michiganairsoft.szm.sk/pics/m4h.jpg

The battery box sits on top of the rail, in front of the RDS (Red Dot Scope) & behind the front steel sight, holding your battery.

No fucking about trying to get it to fit in the underside.

FYI, you can mount on any given rail on the front hand guard, what ever floats your boat.

if its an s system it should fit in the SIR the gun pictured above is a ris vs i own the m4 but made it into a s system and i did go to a peqbox because i got a larger battery but the stock battery should fit in the grip that has two screws on either side that comes off.

The battery fits , but the wiring does not tuck away to the sides , its difficult to explain why but it doesnt and it makes it impossible to close.

Perhaps a ANPEQ is the way to go , the battery connector in my gun is very short though and there is no where it can fit thru on the forgrip to connect to a ANPEQ..

Gah this is quite frusterating, i just wanted to use my first gun without troubles.. now i need to drop more money to get the battery to fit.

I really dont want to tamper with wiring , ect. I really dont want to mess anything up... but now i want a PEQ. Maybe I should see if any locals can help me out in re-jigging this.

oh savage didn mean that though he was saying his was not fitting and didnt want him to get confuzzeled lol as i ddi once when i was a little nub and didnt even know how to plug in a battery lol.
