THE TM MWS thread

[AlphaBear]

Just a heads up for anybody after full size TM mags - Firesupport has had a batch in.  42 left as of this morning, but I have just bagged 3 of those...

I could also use some advice with upping the fps on my newly aquired mk18.  As a recent GBBR convert, I (possibly foolishly) hope to use my MWS as much as possible during the UK winter.  After testing 4 types of gas on Sunday, I was seeing unimpressive fps: around 300 on a .20 using Nuprol 4.0 at 9/10 degrees outside.  It's going to get much colder than this, and 300 fps is not going to cut it against AEG's at a 370 fps Stirling game.

I am really enjoying tinkering with the gun, but have so far just done the GG mod to the mags, which has helped somewhat.  The magazines do not seem to be the weak link, and the winter gases are doing the best they can.  I'm building up courage to have the front end off, but I need to be very careful as I plan to sell the furniture as a TM complete mk18 upgrade kit, as I have other plans for the base gun.

When I do get it apart, I have a 303mm 6.02 lapped barrel to try, and a nub and HSB from Dave on order.  In the meantime, I have borrowed a rocket valve from an old KWA MP9, and switched out the stock TM one.  After leaving mags in the fridge overnight, on Nuprol 3.0 on .20 bb's I chroned at 390 fps, then 380, 363, settling on 340 ish.  

Impressive, but not skirmishable.  Angry Gun adjustable nozzle kits are out of stock everywhere, and when I asked a UK seller about MWS NPAS kits, he said that would not help, as it would not add fps that wasn't there to begin with?

I have put the stock valve back in, but wanted to know if I can modify it to push a little more gas?  Other than this, I think I will have to order something from Hong Kong, but what?

Don’t use Nuprol bbs first point. Either G&G, BLS, Geoffs or Longbow. 
 

Secondly be careful taking the from RIS off I’ve heard it’s a pain to do and some specific tool is needed. I’m not sure if it’s just the normal laylax wrench or what?  It will be interesting to find out. 
 

Thirdly 390fps on 0.2 with Nuorol 3.0 wowzers.... mind you that’s not far off on me clocking in at 387fps on predator gas using a G&P bolt!!! 

I have an Angry Gun adjustable nozzle valve too. I’ve been tinkering with it and it’s now at that sweet spot where it seems happy. I’m getting 340 FPS give or take. Got it from Fire Support when they had stock. Although I’ve gone back to stock Marui and put the gun away till March now. I’ll probably stick it in the classifieds when I get my finger out.

I got a 6.03 370mm inner barrel and with that KWA mp9 valve I’m pushing 520 FPS at 0.20g.

BTW I just installed the Chinese UBR, looks ok but it’s heavy. Also I had to cut 1/3rd of the threaded part as it was going too far into the receiver and the bolt was catching sides (the tube has bit smaller diameter than stock).

I just tried reinstalling the green g&p valve again since I’ve got my own acetech chronograph now and am very bored. At a fairly middle setting as in the picture, I was getting 0.6J with a 0.25. I then tried setting it to the maximum possible setting and got a consistent 1.1J average over half a mag. I was using red gas.
 

If you’re looking to reduce the power of the gun then this valve seems to actually be very good, but at least for this 3.5 type, I am not able to get as much of an increase as I would have hoped over stock.

Weird question 

I know that you mod the full size mags for the green gas efficiency

What about the small 20 rnd mags 

Do you modify them or not

Interesting results. I wonder what affect a 4.0 or even a 4.5 valve would have with a stock length barrel?

And what are the differeces between them? Lenght, weight, stronger spring? These would increase the FPS.

Well I have the G&P springs, watermelon spring, and the G&P 4.5 nozzle but I have another G&P 1.0 nozzle coming as well as a "few" other parts.

Took apart and cleaned the trigger box last night for the first time thanks to the eagle six videos. A bit nerve wracking but I got through it ok.  I'd advise having a half dozen containers or a parts organiser for anyone trying it for the first time as it's easy to get springs mixed up and the trigger itself has two similar but different coil springs in it.

Hardest part by far was removal of the box from the lower which took all manner of gentle levering and tapping with a drift and rubber mallet.

All parts were soaked in rubbing alcohol, scrubbed with an old toothbrush, dried, lubed with wurth advanced dry chain lube and assembled.

I cannot believe how well built these weapons actually are though, the thickness off the lower walls must be 3-4mm and I'd have no fear stripping and doing it all again now.

So well pleased with myself, that's the entire gun stripped to component parts, by me of all people!

Now I know who to send mine to if it ever needs stripping

+1 for the Eagle 6 videos though..... those boys are pucker and hats off to them for all their past videos over the last 10 yrs or so....

Yeah, no way am I good enough to work on anyone elses gun, but thank you for the vote of confidence. I would in all honesty have a go yourself though as it is the final challenge on the MWS in my opinion! And if I'm able then I would imagine anyone could do it with the right tools, patience and above all a methodical work flow.

Yep, I try and buy from eagle six where possible just for that very reason.

Cheers

Redwolf have stock of the Marui nozzles in. About $14 plus $4 shipping to the UK. Great the keep a spare handy.

Will a “Magpul CTR mil-spec stock” fit onto the Tokyo Maruii stock tube?

Yup. But it will be a tad loose due to the variation in dimensions. I live with my wobble ?

Thanks dude, love this gun and can’t wait to skirmish with it after lockdown? I’ve gone through a few mags in the garden and it feels great. I’m fairly new to airsoft and It’s my first gun, I’ve only ever used high cap rentals of which you have to keep winding on the mag after a few shots. Everyone on site kept asking what gun I’m going to get first, I would tell them the MWS, and everyone was like “no,no,no,no, you should get a cheap AEG!” then I would look online and watch videos about the MWS and everyone’s raving about this platform, I’m so glad I was not influenced by the people at my local skirmish site. ? My heart was set on the MWS and I’ve been using a cheap AEG for the last 3 months ?

Welcome to the wolf-pack  And show us a pic of yours......Be wary of BB's. Only use good quality ones at that like G&G, Geoffs, BLS, Longbow.... I had a bad bad experience with Nuprol RZR! It's a great platform to play with and gives a smile each time you pull the trigger... there is a lot of knowledge on this forum and we are here to help as and when we can....

This is mine with a CTR on...

That thing looks incredible!

I have G&G .25 and .28 

I honestly can’t decide on the colour of attachments, after seeing yours I’m starting to lean towards black. I was going for FDE, but the problem with FDE is that some attachments appear really pale in colour and others look dark almost as if nothing is going to match. I was actually surprised at the colour of the original stock, in some pictures online it looked pale, when the gun arrived it was a lot darker, which was good because it suited the darkness of the DD rail.

All the colours never match, even in real steel, look at the HK series, uppers/lowers/rails all come out different shades due to different manufacturers, same applies in airsoft.

To be fair, even with the slight differences in colour shades they still look really nice

Has this been decided yet amongst the community......who makes the best Pmag for MWS?

Ace1Arms, but they still aren't as good as the stock magazines. Ironairsoft also do pmags but apparently they suck major ass. The Ace1Arms one are generally good, although one review I saw said they needed maintenance every 3-4 games? Which seems like a lot since I've used my gun for a few months and only cleaned + relubed the gun...

Well my G&p buffer kit arrived today and it must be me but I've had a nightmare with it, I've two options: either no bolt lock as the buffer tube is wound nearly all the way in with two threads remaining or wound all the way out so it can move up and down and jam on the lower causing a gas out then giving me the final two finger salute by stopping me from lifting the upper from the lower by protruding too far forward and not catching on the spring buffer retaining (stop?) So I have to remove the buffer tube to get it out.

additionally the modify tan hop rubber with super G nub does not seem to be as good as the original tm one to me the best I can get is an 80 to 90 mm group at 20 m. I'm going back to the original hop rubber with super G nub.

Winner winner chicken dinner!
