Yeah, that's a small minus for me too (since we can't buy cheap propane here in Finland and CO2 capsules are a lot cheaper alternative), but what I've heard about how well KJW operates even in cold weather, I can't say I'll miss the CO2 mags. KJW gas mags are said to be the most problem free in any GBBR. Just in comparison, an hour ago one of my standard WE gas mags started to leak again, after some testing with my NPAS. I just hate those WE mags...

 

And it seems that CO2 just speeds up the WE's inherent "self-destruction mechanism". It's like asking for an a55-kicking to use CO2.

 

I'm also kinda tired of screwing the damned capsule covers (either with fingers freezing or fumbling with gloves)... And not knowing which magazine had how much CO2 left in it. Topping off mags with a gas bottle at every reload is the preferred way for me. Simple and fast. And I know for sure that if mag has rounds in it, it has also gas.

 

If it's too cold for KJW (which ain't often), I'll either stay home or use an AEG.

Oh, I've actually never read any cold weather reports related to the KJW. Do you have any urls to share?

I bluntly assumed that propane/gg = propane/gg no matter what system it was used with, but I'm happy to be proven otherwise

 

When it comes to the whole reloading ordeal, I actually quite like the extra momentum due to the fact that I kinda like the extra stress during combat. A magazine shouldn't take 4 seconds to reload ... but then again, I'm a walty little wiener

You do have a point with the whole gas status deal. I find my self a bit to cheap from time to time and rather use a bulb that's been used than actually dumping it and insert a new one ... with the result of me ending up with a spent magazine like 10 BB's in. Insanely irritating

 

But, returning to the KJW even if its hugely off topic. When you say "too cold" and seeing you are from Finland; are we talking -10C or below, or more like 0C?

[Lupus78]

Some people have reported they've been able to use it just fine below freezing temperatures (sluggish but reloads ammo and shoots fine), even around -10 degrees Celsius. I live in southern Finland, where typically there's typically around 0-5 degrees minus in winter. Over 9 months of the year are typically on the + side.

 

But this winter has been exceptional...

 

I'd suggest starting to read KJW M4 thread here at Arnies.

 

I've usually never reloaded DURING the games unless they're very long duration. Not a spray-and-pray type of guy. I might switch to pistol when out of ammo with my rifle.

No. The M16 buffer tube is off course very different and it's longer. The buffer spring is the same, the buffer is the same but the spacer is off course bigger.

 

ah, so there is a spacer inside the m16a3 tube. i wonder what would be the effect if you take out the spacer and put in a longer buffer spring?

[julietcharlie]

Same with an M4 buffer without the spacer your bolt will get stuck in the buffer tube.

[dermonic]

isnt the spring function to push back the bolt?

[julietcharlie]

but the spacer prevents the bolt from travelling too far back the buffer tube

So someone people are talking about KJW mags and CO2. You guys know that theres a CO2 nozzle/adaptor in the market right? Knowing that KJW holds up propane/green gas exceptionally well...at -10C, you can try loading up the KJ mags with CO2 instead.

And potentially lose a hand? The difference between propane and CO2 is a good 650PSI.

That won't work. Unless you put raw liquid CO2 at a good 800/900PSI directly on the mag, using that adapter and putting CO2 in the mag at lower pressures it wouldn't have to enough co2 to fire more than a couple of shots.

Quick question for you guys that have these. I just got mine from RA-TECH and am completly blown away by how it functions. The question I have and that I assume is, this thing pretty much will only accept real steel parts? I'm looking for an Ambi mag catch (I'm left handed) and new stocks and from what I can tell there's very little to no crossover between AEG and GBB parts.

 

Thanks guys,

I'm no tech in GBBr's but as for stocks you have to take RS stocks or their airsoft-replicas which are made for WA or WE GBBr's

Hello !

 

I bought 4 co2 black mags "For SCAR and M4" on RSOV last week.

But my M4 can't keep the mag and it falls each times.

Do you have any idea to help me ?

 

Thank

[Ian24]

And your original mag's still hold well?

[jotohomomoto]

I got the WE KAC PDW GBB last week and the thing malfuntioned right out of the box!!!! The bolt locks back unexpectedly but more often the bolt locks and all the gas rushes out of the magazine. It does this with the green gas mag AND the CO2 mag and it takes forever to change the CO2. Any help would be appreciated.

You've got an old M4 which is not CO2 compatible.

Get the CO2 upgrade kit for your M4 and it should work.

the bolt locks and all the gas rushes out of the magazine

At what position is the bolt in when it does that? Is there plenty of resistance when you pull the bolt back? I'm thinking it's similar to how some CO2 nozzles have their tolerances out of whack and gets stuck in the hop chamber (part #117 on the M4), leaving the bolt stuck and the valve wide open.

Not to deviate this thread from the WE and not to down the platform, but in regards to the comments made on cold weather and the KJW rifle, I was personally able to skirmish with mine in rather cold weather. The coldest it had been during the winter when i played was 19 degrees F. The recoil was a little less remarkable, but I was able to go through 8 magazines each game with the bolt locking back every time. I dont know if this was needed information but I thought it would be good to explain my cold weather experiences with it. There is a vid of me shooting it on youtube somewhere in the cold (not recorded by me) on said 19 degree day, but I dont really have proof of the temp in the vid so it dosnt matter much.

My old mag still works with the rifle (wich is CO2 ready)

If you go some pages back, there's talk about the incompatibility between M4 and SCAR mags in that the SCAR mags have their rubber seal 1mm or so higher than the M4. What happens is you can't seat the SCAR mag in your M4 simply because the rubber part is thicker. Visually check your non-seating mags against the working one. If they're indeed higher, you could just take a sharp knife and file/sandpaper to it and reduce its height.

*remove material on the lower part, not the part that makes contact with the brass tube.

 

If it's not that, have a look at the magazine casing. The ledge that the mag catch engages might not be bent outward enough and just slips. Use a flat screwdriver and pry it out some.

[Anasaan]

Ok, thank you very much i'll try to reduce the height !

[Ian24]

Before begining to sand the thing, just unscrew the screw on top of your mag, pull the rubber seal that contacts with the brass tube out, remove the the little O-ring thats installed between the ruber seal and the gas chamber, put the rubber seal back in place and put the screw in. The whole thing takes maybe 2 minutes for 2 mags.

Your mag will now fit perfectly into your M4 (although sealing will be worse in a SCAR I'm afraid). I've done this for my newly arrived mag's and they work like a charm.

No need to sand anything...

Or he could unscrue one scrue on the top of the mag, lift the feedlip of the mag and remove the small o-ring, yes the diffrence of a scar mag to a M4 mag is ONE small o-ring under the rubber gas feeder lips.
