There’s one for sale in the parts section I do believe. I had to google Maap gas if I’m being honest. it’s all beginning to look a tad ‘inflammable like my bbq lol. So why not just use black gas? Will that not work in colder temperatures?

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?

Is this the floating valve which you have modified ?

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.

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

News flash: Defcon have the MWS mags in... £49/pop. Get them whilst you can Oh and they have the new MK18 MWS in stock too....

Yes you will need a PTS adapter ring from Fire Support about a tenner. The ring goes on the Marui barrel and the MK18 nut screws onto it.... simples

Oh hello......... <porn> Those are magpul sites,,,, I do like that... as a matter of fact I have Magpul PTS Masada lost in the loft somewhere I can nab the sites of that but they are black.. However me being me, I'll probably get a black magpul grip, I'm just too conservative when it comes to mixing colours on my rifle lol... Do it... you know you want too ?. It just makes the rifle look sexy! Although an all black rail would look nice too. I have a 9 inch DD lite rail which I could plonk on to see what it looks like too.

MK18 rail added to my MWS. May get a tan CTR and switch out the grip for a tan RVG. Dunno yet. Judt need some MK18 iron sites now.

Added a MK18 rail. Can’t decide if I need a tan CTR stock now. Already have a tan RVG or shall I leave it as is?

Yeah this was shown earlier in the group... (scroll back a few hundred pages lol)... but seriously the concept is great but I hazard to guess you will need a custom G&P upper receiver as the title to this video suggests... Personally give me a HAO upper receiver and forgo this easy method of taking the HOP out..

Funny you should mention thredlock,.. Fortunately the nozzle I have has blue thread lock on it as standard... I've got it shooting at about 340 fps on Abbey gas at temperature 20c when tested this evening.... Anyway, my replacement Marui nozzle should be here in a couple of weeks along with other gubbins...

So I took the angry gun nozzle apart gave it a clean as it’s wasn’t moving efficiently in bolt. I lubed the rubber buffer with some silicon oil which KoA use for their pistons in their recoil gearboxes. Bloody hell what a difference that made. The nozzle moves effortlessly and you can even hear the air moving in the nozzle (well the suction type noise). The stock marui nozzle didn’t have the same affect. The stock marui nozzle just falls straight into the bolt whereas the Angry Gun has that suction resistance. Either the AA rubber buffer is a tad too big or the Marui one is a tad too worn. Dunno. Someone explain to me which is correct please? On to chrono time. Fully gassed up mag on Abbey Predator gas at room temperature of 20c. Using some 0.2s first shot 371, then consistently 366 for the next few slowly going down to 358 on average. The AA valve will need more adjusting to decrease the gas flow. Other than that she’s back to normal! Whoop! Happy days. Oh, the marui hop has 15 click positions. I know coz I counted each click lol. Twice. Using a stock marui rubber and a brass nub the 0.3s which I subsequently used needed 7 clicks of hop for a stable flight. Don’t know if that info is useful for anyone?

Another question... How does one attach a Mk18 rail or any rail as a matter of fact that has those attachment bolts on the collar nut... The bolts could potentially smack against the receiver causing damage. that's what happened to that chap that was selling his MWS on Prefired... Incidentally, I have a PTS barrel ring which fire support sell and I don't think that's appropriate to use? Or if it is how do you use it with the rails? https://www.fire-support.co.uk/product/pts-adapter-ring-for-marui-m4-mws-gbb

So whilst waiting for my bits to arrive from the Far East, I decided to try an Angry Gun MPA nozzle. It’s the one where you can vary the FPS. I put it into the bolt carrier with the valve opened fully (vary it use an Allen key which is supplied), pumped up mag with Abbey Ultra and stuck in some Geoff’s 0.30’s and it chrono 330-350fps!! This was on a full gassed up mag. Needless to say I was kinda surprised and the mag used its gas pretty fast. So, I adjusted the valve with a lot of trial and error and got it down to 280fps. Negatives: 1. There is a twang each time time the bolt cycles forward. It’s coming from the spring. I hazard to guess that there is no tubing in the spring which is this causes the spring to resonate 2. Bbs- It seems to be pushing a bb into the chamber perhaps a tad too far and it rolls out of the barrel. I was testing on zero hop using a marui bucking and the SixG nub. I’ll set the hop for 0.3s and try again. 3. The FPS consistency isn’t as good as I was expecting. There is way too much variation. I think this may need to go back!

Thank you. That was exactly the info I was looking for.

G&P npas, they make various versions like 3.5,4.0,4.5 etc.. Do these figures represent the maximum fps on 0.2's and is anyone using the npas valve kit? To get close to 350fps what 'type' of gas would be needed and of course I assume a npas flow valve will be needed in addition to some other more resilient upgrades over the stock parts?

They sell a gold edition of the MTR apparently if that is your thing. https://www.defconairsoft.co.uk/product/tokyo-marui-mtr16-g-edition-gbb-with-zet-system/

May I ask, are your MWS’s stock internals? And is there a power increase with Nuprol 3.0?

It should run fine on Abbey Ultra Predator gas (the red bottle)... the green bottle may just have a tad less power... Just keep the mags warmish Report back after the weekend with your findings

Now I'm thinking blingy gold but that would be too 'gangsta' right? Silver would be a nice colour option for the bolt... better than having a black bolt with it's paint getting all scratched off like what happens with the Marui one.....

@Speedbird_666look look

OK, best BB's to use in these beasts? I understand a GBBR is quite brutal in loading bb's one needs to use the hardest almost most perfect bb's out here. I foolishly used Nuprol RZR 0.28's which I believe shattered and caused my nozzle and rubber to go tit's up.... So without further adieu what is it you chaps recommend? Geoff's super precision I assume are the best to use? Incidentally, I spoke to firesupport and they said use a hard bb and said G&G 0.28's and higher are very good for GBBRs?

Chaps, is the bolt carrier group the same dimensions for all the MWS models. I’ve got the CQBR version so wanted to confirm that if something says compatable with MWS M4A1 it means by default CQBR too.

Standard service is normal airmail or in this case HK post so can take from 10 days plus. EMS and DHL will be here within 5 days. However due to Covid EMS times were well buggered so many people used the DHL route. You’ll be paying $30usd more the faster shipping. That’s lost beer money ? I’ve got a stock nozzle nozzle (to replace the one I buggered up) coming In from Taiwan as a matter of fact probably about 10 days or so. I used bang bang airsoft lol. However I’m seriously considering the whole G&P bolt carrier group too. In the U.K. the max limit is 350fps so the 3.5 npas I believe is what’s needed.
