THE TM MWS thread

[jsmithski]

So basically, when it is cold gotta use a different gas. What I was just concerned about is that if you can own a MWS here in the UK and be able to use it most of the year, I do not mind if I need to upgrade it or use different gas, also. For CQB I guess it wont be as bad as the temperature inside is higher right? 

Thanks for everything.

Depends on the site, I played indoor cqb in the winter where the temp was same as outside. You do not need to upgrade internals for mapp gas if you use it when it’s cold - it will have the same effect on the gun as green gas when it’s warm. The fun starts when you’re looking for more recoil or FPS or both and switch to a more powerful gas when it’s warm thus increasing the wear on internals - then you need upgrades. Anyway, gas guns are so much fun I don’t mind the additional maintenance, fiddling with it it’s also part of this hobby (at least for me).

I am still trying to figure out how to quote someone as I am new to using forums, but I have the same thing, I think they are so much fun I really don´t care about all the extra stuff that they need done. I have to be careful with wanting more FPS as here in NI we have a law that they cant go over 328fps or 1 Joule which is quite annoying to be fair.

Today I made a DIY npas using stock floating valve and m3x8mm set screw. Works just like any other npas but I think 8mm is too long and eventually 5mm screw would be enough. I was able to get consistent FPS so I think it makes no sense in spending money on the commercial stuff. This is my second npas (first I made for the vfc mp5 gbb), it’s a simple job anyone can do.

An MWS at 1j is quite a tool, you really don’t need any more power.

For colder days run Red has / propane etc.

Upgrades wise a lightweight BCG will help cycle speeds around 0C.

Likewise you can run the above all year with an NPAS type valve and adjust it to suit time of year / site FPS regulations.

Thanks a lot Dave, Now with all of this semi lockdown going on in here, ill wait a bit to get my MWS but ill be getting one for sure, I will start looking into the upgrades world like the NPAS whenever I finally have it at home.

I don’t have any numbers, I can get it to you this weekend if I go out skirmishing as it’s going to be below 10C. Mapp gas brand does not matter, internal upgrades are not needed as mapp gas in cold weather will have same pressure output as green gas on a warm day. But indeed some math should be done here.

Cheers, I'm fairly stock internally just an npas that is relevant but the bit I'm really after is the figures as I'm running an original BCG with a bit of saving up for a lightweight option ( is the g&p a lightweight number as I don't like Angry Gun stuff - had a couple of gash items from them).

Anyway any knowledge would be great, perhaps if we could nail it down to ballpark figures for a stock gun we could add it the downloadable mws thread document that's on here to cut down on repeat questions as this thread is huge.

Well that’s quite interesting. Do you have any pics of the components you used and also the final assembly?

This is what you need to do.

Tech tip: if your original handguard wobbles, it is most likely a stripped screw at the bottom of the barrel. Using a few mm longer one will fix it, there’s much more room and the original screw is very short. Since original threading is short you will need use some force to screw in the longer one, but you can do that without a threading tool.

Ahhhhh I see what you mean now. That’s kinda similar to the Angry Gun MPA nozzle I’m trying it. You can adjust the screw using an Allen key and it has a washer attached to the screw to limit the gas flow.

Here there’s no washer, the screw positions the floating valve by pushing it off the nozzle spring retainer.

Question to you all, what’s the trick to make the MWS sound like Inokatsu? If you ever heard how Inokatsu m4 sounds then you know what I’m talking about. Anyone has an idea?

 

[AlphaBear]

Is this the floating valve which you have modified ?

Yes, the one on my pic is from the mp5, but that’s the same part just different shape. You insert the screw from the inside so that you can use an Allen key later to turn it just like the angry gun npas.

So I have realised that basically everybody here already has this gun and to be honest, I am my self close on getting one my self. But I have a few concerns that make me a bit unsure of getting it and I hope you fellow already owners can clear my doubts. 

Now, I have fallen in love with the gas blowback mechanic, and I heard about how good this m4 from tm was,  the problem is pretty simple, I have never worked with gas outside of using gas at home for cooking to be fair. I have no idea how well this sort of gun is going to be able to perform or even survive in the somewhat cold weather we have here in Nothern Ireland, I do not expect it to compare to AEG, or to be amazing in the field, but I don´t want the gun to die on me either because it is not made to work correctly in this temperatures. Is the temperature something that would end up being a terrible problem? Any sort of help towards this would be incredible appreciated as I am really just looking for any excuse to buy it, but I have a local airsoft store owner scare me away from getting a gbbr on here Belfast, I´ve heard that it also goes down to the rifle being good? Some brands and some rifles are made better therefore being able to still perform decently in cold weathers? 

I apologise for asking so many questions, but thanks a lot if anybody does answer them.

Have an amazing day. 

Honestly, since I started playing with gas blowback, I've had precisely zero interest in AEGs.  My first was a GHK G5, then a G&G SMC9, and now the MWS.  The other two are fun and I suspect the GHK would run even coated in mud, but the MWS is a dramatically finer piece of equipment than either of the other two.  The only place where the "performance" lags an AEG in my opinion, is in the ability to just pull the trigger hundreds of times without swapping mags.  All that results in is wasting bbs, really.  The overall feel and experience of playing GBB makes the AEG pale in comparison and the MWS is about as good as it gets in GBBs.  Had I known then what I know now, I would have just gotten the MWS in the first place and save myself quite a lot of money.

I don't know about truly cold weather but I've played in temps down to about 45F (not cold, I know) with no issues at all.  Frankly as a Californian I'm spoiled to warmer weather and really wouldn't want to play in freezing temps anyway, as I haven't found a good way to keep my goggles from fogging at those lower temps.

Oh yes! When it worked it was such a ferocious beast. Lots of metal on metal. Good clunky AR trigger, bolt dragging over the hammer and it’s metal nozzle coming down on the chamber like a hammer on an anvil. I think that was one of the keys to its roar, the metal nozzle.  
 

The Marui M4 has too many plastic components that act like dampeners and those roller bearings don’t help.

Second outing with MWS today and after using red gas (nuprol 3) it was fantastic couldn't get enough.

Managed to get 2 full mags out of one gas (12c) which is what I'd expect, just looking for a good red dot now and should be perfect.

Oh and a rear sling plate.

 

[jsmithski]

Some info regarding Mapp Gas. Today I was out playing in the cold: 9C but no wind. I did a test using 3 different gases, so here are the results:

14kg Puff Dino: 1J

Smart Gas Power Green Gas (they claim it works in low temps): 1.16J

Mapp Gas: 1.2J

But the real difference was in recoil and cool down. Mapp had no issue firing on full auto even after I emptied the mag by releasing all gas at once (so the mag was really cold). Sorry for no pictures or video but I had no one to help me with that today. I will continue testing even in lower temp.

Sounds promising..... although I may leave my MWS for the warmer months. Unless that is next Sunday we have a heat wave? What’s the chances of that? Hmmmm?

By the way, why do you need a rear sling plate. The MWS comes with one already yeah?

My MWS didn't come with a sling plate able to put a sling through. Just a blank one.

Apologies for putting it here and not as a wanted in the classifieds, here just makes more sense to me!

Don't suppose any of you fine folks have a stock trigger (part number MGG2-44) and/or trigger guard pin (part number MGG2-145) going spare that you'd consider selling?

In the process of taking the GRY kit off mine and have found out the seller opted to not include a majority of the fittings or the stock trigger which was a LOVELY surprise. Not spotting the trigger wasn't there is admittedly my fault for missing something so obvious, and I'd foolishly assumed all the fittings were in the box of bits... silly me. PIcked up a few bits from the classifieds on here and was going to order these two parts from Eagle6 (both in stock this afternoon), only to find out the hammer unit is now out of stock. Another lovely surprise. On the verge of assuming this RIF is cursed and chucking it in the cupboard for the foreseeable future!

Links to the two parts I'm looking for are below, Impulse101 is the other option but I imagine I'm looking at a fair old wait for that to arrive so figured I'd chance it!

https://eagle6.co.uk/shop/catalog/product/view/id/3037/s/tokyo-marui-m4a1-mws-lower-frame-trigger-guard-pin-for-m4-gbbr-series/ (Yes, that's £6 for a bloody pin... but none of the ones in my box of tricks fit)

An another note, has anyone used the UAC Steel Hammer set? I've had to open the hammer unit as is and have one of these sets. Weighing up if it's worth throwing it in there while I've got it in bits.
