Tokyo Marui MWS Magazine Mod - 3x More Gas!

[@ashir555]

Finally someone does this in a proper way: you don't need to cut all the way up to the brass piece! If you do it you will lose the spourting indication that yhe mag is full.

[@astragreen]

Thanks for the tip that’s really important in my view!.

[@ulmo17]

Okay you got 3x more gas but what about mag temp when you start using it? Does it effect efficiency?

[@astragreen]

Great job absolutely marvellous!.

[@FlightAce100]

I like it. I wonder though why they didn't just design them like this from the factory? Why did they make the stem go 2/3rds the way down to begin with? Seems like it would have been any easy way to gain an advantage over their opposition.

[@Bastyxx227]

Prolly because some rule in Japan, or maybe because they dont use green gas but "duster gas" which has less pressure, so the design makes sense with duster gas in mind Remember Tokyo Marui is based in Japan, and most Japanese companies don't give a crap about international market, they sell to us but don't consider us when making design decisions

[@astragreen]

I think you got a point there japan has some strange laws regarding Airsoft (adult toy ‘guns’)!.

[@Alex-vz2jz]

Probably to increase reliability? That's my guess

[@richielee5398]

It's probably so if your gun isn't upright that you would have liquid gas coming out when you are shooting it which could cool your hop rubber down. I've seen them modified by cutting the tube in half which still allows the gun to be used at a fair angle without it blasting gas. I've not done mine yet but be interesting to hear if people are getting this issue when the mag is full of gas.

[@federicozeni2882]

Is this modification also possible with the original Double Eagle magazines for N4?

[@jockeycorundum6949]

Great video mate, any tips for loading them with gas? you using any of the 'popular' methods such as 8/10 secs fill? :D

[@Jaeger-Precision]

Fill it till its full

[@hemek]

Just curious about it - I'm looking at doing this mod but my mate is saying you don't need to do this for V2 mags - I'm having ineffiency with gas in my mags but TLDR, how can I tell if I should do this mod or not....packaging didn't stand out to me (at least) to say it was V2 mags but they were "new"

[@Jaeger-Precision]

no such thing. I have magazines deignated as even later versions. It still needs doing.

[@jamesterry1341]

very imformative and well put together video, I was just wondering tho have u had any problems with the modified magazines spirting liquid gas into the replica? and are you still able to shoot quickly in semi afer the mod without dramatic cooldown? can you still use auto?

[@Jaeger-Precision]

Been using this for years. So far 0 problems. I do use propane though and not green gas

[@jamesterry1341]

@@Jaeger-Precision okay thank you for the reponse

[@cienfuegos569]

So helpful. Thanks for share it. 👌😉

[@fmpairsoft9039]

If I'm correct, the same thing can be accomplished by replacing the fill valves with the nine ball ones, right?

[@AkashBhambra]

Just wondering is there any replacement for the part MGG2-83? The part you saw in the video? I’ve been looking and have had no luck :(

[@GabSte1989]

What's that in the top right? Looks like a weird SVD type or a garand with magazine (M69 or whatever the italians named it)

[@jefferychow4765]

Does this increase the pressure? Is the magazine strong enough to handle it if so?

[@LuisPereira-fv3fh]

Thank you, it helped me. 👌🏻

[@postal5342]

Pro tip. Instead of using a saw use a small pipe cutter.

[@peter11256]

Nice, is it possible to increase the BB capacity as well ? Maybe to around 50 bbs or something.

[@Jaeger-Precision]

Unfortunately not

[@kiketorrenak47]

I'll try to add at least 5bbs with some mod

[@Alex-vz2jz]

You cut into your mag and make it curl like AEG magazine, then you'll have to block off and seal that area so no gas leaks out.

[@williamsalazar244]

Will this work for 300 blk L5 mws green gas mags?

[@robsmith2625]

I have done the mod successfully with all mags apart from 1 where the stem broke off and I'd now stuck in the housing, therefore when filling mags the gas is not penetrative properly. Is there anywhere I can purchase the valve and outer bit, basically the entire part that comes out with the valve with the tube attached? Look forward to your reply:)

[@Jaeger-Precision]

Send me an email with some pictures

[@FXTRT1-1]

On my mags, the inlet valve where you put the green gas nozzle in, they dont like that, if i put a 134a gas nuzzle on the valve it doesnt "leak" but on green gas cans, i think it spits out gas as i am filling up the mags...anyone else have this?

[@jpisback]

It's a common thing with the TM Stanags. Something to do with gg cans pushing more gas out than the fill valve is designed for, so the extra gas is forced outwards. an oring can help cut down on this.

[@messa.productions]

Just shake the mag?

[@edmundddd]

Hi mate, how do I ship my mags to you to perform this service ? I would like these done to my mags but I don't have the equipment myself and more than happy to pay you to do them for me. Let me know, thank you!

[@thisdewd007]

Great video!

[@Jaeger-Precision]

Glad you enjoyed it 😀

[@blusox78]

Has anyone chrono'd their gun before and after this mod? Surely adding that much more liquid gas means that as it expands into a gas the pressure in the mag increases, especially on a warm day, and therefore your gun could be running hot.

[@Jaeger-Precision]

Thats not how it works. The gas still expands at the same pressure. You are just filling it with more liquid.

[@astragreen]

Ollie Talks Airsoft does a video on that very subject!

[@Freman17]

Seems legit, but what about overflowing magazine? Bcos of this mod you have much more gas in magazine that manufacturer wanted, what about internal parts? I read that overflowing not modified magazines causes a lot of problems, whit this mod it seems it will get even worse?

[@Jaeger-Precision]

Ive been running this mod since the MWS was released all those years ago. Never had an issue

[@Freman17]

@@Jaeger-Precision thats quite good and very usefull information, thanks!

[@algebra358]

Any draw backs with this modification? As they say for every gain you lose something else. Please let me know..

[@Jaeger-Precision]

None

[@Bastyxx227]

@singlespeedpunk7744 With this method, leaving part of the rod in there, you should have plenty of gas in the mag without worrying about it, as long as you don't tilt the mag to "fill it up" even more. But if you fucked it and ripped off the whole thing, yeah only like 10-12 seconds of filling so you leave space for the gas

[@MrRiingo]

Should I do this with the Guns Modify EVO MWS mags too?

[@Jaeger-Precision]

no need to

[@CallsignHicks]

Is this for a gen mags or just the 1st?

[@Jaeger-Precision]

All magazines require it. The myth that mags with the number 2 stamped on them dont require it is false.

[@CallsignHicks]

@@Jaeger-Precision okay thank you for clarifying that as I wasn't sure :)

[@CompoundAirsoft]

Can this be done on Glock mags as well or..... nah?

[@Jaeger-Precision]

The glock magazines do not have this

[@nightscapechannel]

Nice!

[@ccc7596]

Very informative video. What gas would you recomend for a MWS?

[@Jaeger-Precision]

Propane was the best in all my tests. But at minimum use green gas.

[@Jayda08]

Just hold the mag right side up while filling it.

[@thememelord7684]

Hey bro one of my mags doesn’t want to take propane, like it immediately spits it out could you help?

[@Jaeger-Precision]

It wont be a propane issue it will be a magazine issue. Where does it leak from top or bottom?

[@thememelord7684]

@@Jaeger-Precision from the top on the fill valve it just leaks gas almost immediately

No

[@tex1297]

And the engineers at Tokyo Marui:🤦. People think that this part is just so long without any reason?

[@Jaeger-Precision]

I understand there is a reason as well as me having a reason for removing it.

[@gattosquad2241]

At the risk of sounding like an idiot, how does this increase capacity? aside from the tiny bit of material removed there shouldnt be a change... you shouldnt get a different capacity because the chamber is still at the same pressure no matter where it's feeding from, that's the whole reason why gas mags work. .5g of plastic/metal displacement shouldnt change it that much.

[@Jaeger-Precision]

If you pay attention I explain why

[@gattosquad2241]

@@Jaeger-Precision So why not just fill the mags at and angle rather than open them up and cut things?

[@Bastyxx227]

Bro it is literally explained in the first 4 minutes

[@gattosquad2241]

@@Bastyxx227 You can "explain" anything, from a gas physics point of view it makes dramatically less sense than you think.

[@sheepmasterrace]

It’s because of this concept called “vapor pressure.” At vapor pressure, a substance can exist as both a gas and a liquid. Below vapor pressure, a substance can only exist as a gas. (Think why Mars doesn’t have liquid water: Mars has such a low atmospheric pressure that it’s below the vapor pressure of water, so water can only exist as a gas) When filling a mag with propane, the gaseous propane builds up until it reaches the vapor pressure of propane. At 80 F, the vapor pressure of propane is 128 PSI. Once 128 PSI is reached, you could basically consider this as ‘maximum pressure’ (assuming the temperature remains constant). When you charge more propane past 128 PSI, the propane begins converting into a liquid The liquid begins to fill the magazine, and then reaches the metal tube. This blocks any more gas from entering the magazine, so the gas begins to spill out of the fill valve. Same concept as when you blow bubbles into a glass of water. It’s takes some force right? Gas always wants to take the path of least resistance, so rather than ‘forcing’ itself past the liquid, it will simple take the easy way out and leave the magazine

Hubiera sido bueno hacer la prueba de rendimiento! GRACIAS @airsoftcta

[@nightscapechannel]

Will this work on a guns modify v2 pmag?

[@Jaeger-Precision]

No

[@nightscapechannel]

​@Jaeger-Precision would you happen to know if the guns modify pmag holds just as much at the tm mags (post modded)? If not, is there a different method to do the same thing to the pmag so it could hold more gas?

[@Jaeger-Precision]

@nightscapechannel the pmag holds plenty of gas. It doesn't need modding.

[@nightscapechannel]

@Jaeger-Precision I have a single Type89 mws magazine. Will this work on that magazine as well?
