Why do you want silent filling?
 
Marui valves dont have O rings.
 
Its easier to fill the Marui valves as they let expelled air out when gas goes in, so they fill faster, plus you know 100% when they are full as they burp out liquid.

Well congrats guys you've converted another. I already have a GBBR. It's a very nice very rare G&P WOC SR-15 in beautiful condition with 7 50 round mags and now all I can think about is how many mags I'd get with an MWS if I sold them all... You bastards

Someone correct me if I’m wrong, but I’m pretty sure you can’t use a RS charging handle in the MWS

I think you need some more mags.

Brothers

Finally got all my accessories for my sniper rifle
 

Selling “upgraded gun” - doesn’t mention any upgrades other than a hot spring 
 
What’s with the tape on the stock as well?? 😂

Marushin stainless 8mm Automag. Pictured next to my ky airsoft Colt traded WE CT25 just to emphasise it's enormity.
 

The modify tan is a great bucking and a good choice for the orga and SixG nub. Seems like the orga barrel window doesn’t like long contact patches like the TNT or maple leaf. 

Put a GG&G mount (courtesy of @Jacket) onto my MWS, and put the Magpul sling mount onto the MP7. MP7 now sports my Eotech, sadly too small for the magnifier.
 
Just waiting on a one-point S&S Precision sling for the MP7 and I might be happy with it...for the next week.
 
Happy with the MWS and aiming to use some Geoff's 0.30gs through it on Sunday.
 
D-bal and a light next for the MP7...
 
If anyone is in need of some pouches (MC and CB), hit me up. Need some funds now...

Got my replacement mag seals fitted to my FNX. I do love HK, but FN are right up there with them.
 

Realistically it seems to be about 3 (feet = yards), which http://www.age-converter.com/horse-age-calculator.html suggests is horse years.

Is a 40mike gonna even reach out to 30m?

Different crop plus Cat and grip box missing in 2nd shot...

Real steel magpul pistol grip. Exterior build is nearly finished 😎
 
Diesel May have had a paw in on it 👀

They’ll be doing the same from their suppliers😂 do patrolbase hold any stock at all?

I hear the USN are using parcel tape as camouflage for their new F-35s.
 
Easy to source, even a kid can apply it.

Just remembered, it’s school holidays 🤦🏻‍♂️

Nice one. Makes sense as there’s no proper trades on it. It just sits in my parts bin as I’ve never been one for mk18’s😂

Pretty sure you got a VFC mate.
I've a VFC myself and it look exactly the same color. I also got a madbull and this one is definitely not a madbull because off the color

As a lot of threads end up with one of us recommending the Tokyo Marui MWS, and i get PM's asking about it, i figured I'd start a thread to keep all of the information in one place. Here i plan on covering a general overview of the gun, as well as upgrade parts, general maintenance and tuning. If anyone else wants to share any information, guides or even gameplay with their MWS, here is the place to do it. With that being said, lets get on with it.
 
I've had my 2  Tm m4 GBBR's for a little over a year now, and they've got through dozens of changes to get them where they are today. Out of the box they are beautifully finished and boast impressive performance. I bought my first one from Zeroone, who price matched it for me. At the time the gun set me back £430 and the magazines £35, but they have risen quite a bit in price in most places. 

The gun is incredibly well finished and sports a Cerakoted receiver. Before opening the box, i didn't get what the big deal was about Cerakote, but that all changed after using it over time. The finish is VERY resistant to the hard life I've shown it, and is far more scratch resistant than any paint or anodization on any other gun I've owned. The two I have still don't have a scratch on them. At the rear is a standard m4 stock, which does its job with little wobble, but isn't the nicest one I've ever seen. The railed handguard is very solid and nicely finished with all of the correct numbered markings on the rails. From there you have your usual front triangle iron sight which DOES NOT have a sling attachment at the base.
 

The magazines hold 35 BB's and have a Cerakoted shell to keep them from scratching easily. They have very recently started coming with silent fill valves, but are mostly the normal kind that hiss when filling and spray liquid propane when full. Its worth noting that the valve sits at an angle to the baseplate. One modification i would highly recommend to do is the "green gas mod" which involves removing a long zinc tube from inside the magazine. This allows more gas into the magazine and upping your shots per gas fill dramatically, with some people reporting 150+ shots from a single gas charge. As a side note, i have started to just cut the zinc tube about 1 inch from the base instead of removing it entirely. A video showing how to do it: 
 
Chronograph Results:
using blaster .20 BB's and green gas i got around 298 fps with a deviation of 2FPS. yes, you heard that right, " FPS. This thing is incredibly consistent!
 
Important information:
The inner barrel is 250mm on the 10.5 " CQBR and the 14.5" carbine, meaning on the 14.5" outer you can fit a much longer 370mm inner barrel. The Hop up adjustment dial is similar to Tm pistols and can be located inside the upper receiver by locking the bolt back and looking down the magwell. Due to the way the outer barrel is cut, it's not possible to fit an aftermarket rail onto the gun without one of two things. A barrel adapter ring (PTS, ORGA and a couple of others make them and usually cost £10) or A dytac outer barrel, which has a wider lip, as shown below. Dytac on the left

 
First shots:
I took it down to the 20m range at the First and only shop and loaded it up with .28 blaster devils. They had multiple targets there, but i focused on the little spinning targets at the back wall. The orange discs must have been no more than 1.5 inches in diameter and i was hitting it virtually every time with the iron sights. So far, very impressed with the accuracy. So much so, I treated it to a new dress!

 
First internal upgrades:
After speaking with Dave about the gun, he explained that the gun wouldnt hop really heavy weight BB's with the standard nub. because it was hollow and squished when applying hop pressure. To remedy this he machined me a great little nub out of brass. Isn't it beautiful!?

This meant i could now lift much heavier BB's increasing my range and accuracy even further than the already impressive stock performance. Using this new nub and GEOFF .32 bb''s i was able to get the bb's out 60+M with a flat trajectory. They were making a 1.5-2ft grouping on the plastic bales as seen in the video below.
 
I have SOOO much move to cover, including barrel reviews, customs mods and a DMR build, but its 5;30 am and i need to be up in an hour, so we'll continue this tomorrow
 

I have (mostly) finished my mk18 build. I’m going to be looking at other torch options, mainly because I’m not happy with the one I have and I’ve also seem to have misplaced the pressure pad! 
 
The information in this thread has been really great, just a quick thanks to everyone!
 
The main upgrades are: 
 
Laylax 6.03 250mm inner barrel 
Modify hop rubber 
Laylax hop arm (will pick up a super nub in the future). 
Mad bull mk18 rail
a low profile gas block and spacer (both of which I can’t recall what they are exactly)
Magpul stock, AFG and grip
Raptor style charging handle 
Vortex crossfire red dot with back up irons 
 
There was a few issues with fitting the rail that took about 30 minutes to resolve. I’ll add my mistakes here:
 
- The coupling that has all the screw holes does not have a continuous gas tube hole. So you either have to drill a hole, or cut the gas tube down. I would really recommend against drilling the hole, as there is an internal step down that leaves no room for error and you may end up splitting the coupling. I started drilling and then stopped once I realised it wasn’t an easy exercise with the tools I had.
 
- The barrel nut has to be tightened a fair bit to stop the rail from twisting very slightly once it’s on. I also added card shims either side of the tabs of the coupling. The tabs slot against the receiver and the shims gave it a tighter fit. For now, it’s very sturdy and in line. 
 
I quite like like the black finish on the rail, but this is preference.
 
While it performs great, i have to say there isn’t hardly any difference from the stock barrel. Although I’ve only done some basic testing. The accuracy of the stock rifle (and barrel) is quite decent. Also, by adding the 6.03 barrel the fps stayed the same (around 295 on 0.25s). 
 
I’ll  keep the laylax hop arm for now, but will likely get a nub in the future. I know a lot in this thread use heavier bb’s and reach really long ranges, but for now I only stick to CQB and urban sites. I’m quite new to airsoft so that may change few months down the line. I’ll probably end up playing around with it more! 
 
Oh and I should also add she hasn’t been skirmish tested yet, but that’s coming up in three weeks. I only have a total of 3 mags though!
