Long time; no fettling. Getting the MWS ready for next weekend and had a play about with some Guns Modify parts. There is an issue where the MWS can self-adjust the hop down as it cycles. This is due to the gas key / guide part rubbing on the hop wheel. I have had this with a very worn TM one (4-5years use) and a new AngryGun one (shocker!) Today I fitted a Guns Modify one and have put a couple of mags through it and found no loss of hop-up. Seems the little cut out at the front is deeper and wider than others. None in stock but sign up for a reminder: https://www.fire-support.co.uk/product/guns-modify-enhanced-nozzle-reset-for-marui-mws-m4-gbb-v2 The second fettling was with the rocket valve - I was running one that I had sanded down by 0.5mm and that worked well during winter temps (sub 10DegC) but was a bit spicy now spring is here! A full length, unmodified, one gave around 245fps, the 0.5mm shorter one around 279fps (ASG Gas, 0.32g BBs, your mileage WILL vary!) I carefully sanded a new one down approx 0.15mm on some medium wet&dry and that tested at around 258fps at 17DegC so exactly 1J With the mag warmed to 22DegC it was stable at 268fps so under the 276fps limit for 0.32g I am happy to run this during the summer without having to resort to very weak gas or lighter BBs. GM do these as a pack of three so you can have a play about with the power and not have to worry about set screws self adjusting and causing issues. Take it slow and keep checking with some digital calipers 😁 Available now: https://www.fire-support.co.uk/product/gun-modify-high-stability--fps-diy-valve-for-marui--gm-mws-m4-gbb-v3-nozzle-3pcs

TM MWS hop up clicker plunger got fired across the workshop earlier…..and I found it after only a few minutes searching! Bloody stupid design 😂

What are you're rig/vest recommendations
SSPKali replied to Gavin W's topic in Guns, Gear & Loadouts
While I have SADF M83 battle jacket and chest rig <flex> I find I am running my more minimal ones. Spiritus MkV (like the regular mini chest rig but only one pocket deep) with 3x M4 mags and a pistol-mag sized speed loader in a Esstac Kywi on the side to top up the M4 gas mags. Axle dangler plate holds a LBX blowout pouch underneath for a basic first aid kit (and protect my gut a bit!) -
ASG Beige gas is about the same as Nuprol 2.0 in terms of pressure. Abbey 144a is lower than Nuprol 1.0 “white gas” and should get it under the limit even on warm days.

Silent fill valve o-rings removed and fill tubes replaced with 7mm ID stainless steel tube, 50mm length from the brass threads. This is a bit less than stock but still gives a good space for the gas to fill above the liquid. The stainless tube is a snug push fit over the alu tube so with some grease and percussive maintenance it goes on and stays on 👍 I filled the mag with ASG beige gas until it spluttered, then tilted and got another 1s worth of fill. Bearing in mind it is quite cool today I was able to fire 140 shots and still have it lock back, the mag was pretty cold by then so I popped it in my pocket for 30sec while I got some BBs and turned on the chrono. It was putting out 230fps on 0.32g and locked back after the 14 shots I fired. Pretty damn amazing! Right, beer o’clock 🍺 “Tell me you know nothing about GBBRs, without telling me you know nothing about GBBRs” 😂

Anyone got tips for getting “silent fill o-rings” out of TM valves? Digging with a needle isn’t getting anywhere….

Tested ASG Beige gas against Abbey 144a in my MWS, probably about 18DegC.
ASG = 1.08J
Abbey = 0.86J.
(270fps vs 240fps on 0.32g)
Will keep a bottle on-hand for those warm summers days. ASG was reading 268 - 272fps yesterday at UCAP Gloucester when it was 20-22DegC so close to the limit. Nuprol white was 255 - 260ish.

You're costing me a fortune in gas dude! Seriously though, this is really useful. Hoping to get to the range next Saturday and will run through the three Vorsk gases I've got, and ASG orange and red. I'll use .32s as well as that's what I'll be running as standard.
In other news I've ordered a Titan nub from Jaeger so may fit that too if it gets here in time.

I have settled on the stock TM bolt with: HAO steel bolt end, AG alu buffer and 110% buffer spring - this is great in warm weather, still lets me get 70+ shots from a mag and gives a nice kick. Winter set up is the stock bolt end, stock plastic buffer and G&P buffer spring (comparable to TM stock) - this gets maximum from the gas efficiency without removing all feedback and turning it into a glorified NGRS with extra steps. Unless you have shares in propane manufacturers I would steer clear of AG steel buffer and / or 130% buffer spring. It still isn’t close to the feel of a 5.56 M4 plus you will never have the “fun” of the 10” barrel fireball 😂 My MWS came with the Laylax hop arm with inbuilt nub so not played about with other options as happy with it. Think there is a ML MR hop in there at the moment, stock TM and Modify Tan are both good.

Need to drop some FPS? Superglue and baking powder on the back of the rocket valve will knock some power off. Mine went from 290 down to 240fps on a 0.32g
-
So if you have a TM MWS and you need to drop the FPS (maybe after a longer barrel or other changes that can tip it over the limit) try this one crazy trick!
Take out the plastic rocket valve and LIGHTLY rough up the flat back part, cover in thin layer of superglue and dip the end in baking powder. Dust off and repeat.
Clean up the edges to it moves freely in the nozzle and re-assemble.
Mine went from 290+ fps down to 240fps (0.32g) in 18DegC on ASG beige gas! Less than a mm of extra length makes all the difference! (Ooh err Matron!)
YMMV, messing about with internals like this might break things, get an adult to help, I am not liable for anything, ever. -
Hillbilly NVG mount.....he dangles a carrot off it 🤣
-
Finally finished faffing around with nozzles, valves, blockers and springs and the MWS. TM nozzles give 45fps LESS than the Guns Modify nozzles....DP aluminium valve adds 100fps over the GM plastic one...two identical valve springs vary by 15fps...
Steel bolt is shooting at 1.08J, spare nozzle gives 1.07J.
Spare Aluminium bolt has a NPAS in so can dial it up or down (and hopefully it won't self adjust!)- Show previous comments 2 more

Ah, interesting. I've always been happy with my stock MWS (apart from replacing the nub with a SixG) but my second one I'm happy having a bit of a play around with.
I'm fascinated by the stuff you've been doing so I'm really interested to see what else you're coming up with.
Incidentally, have you seen that BavTac are working on titanium bolt weights?
-
Mine came with a Crazyjet barrel (+20fps) and running 0.32g means you get Joule creep. In warm weather an NPAS or carefully selected nozzle parts are needed to keep it under 1.13J
I am surprised by the variance in output with things like rocket valves and nozzle brands. I would make a chart of them but given the seemingly random QA and materials in airsoft I am not sure it would be useful!

Having played at Warzone last weekend I realised my elderly eyes need some help on PIDing people at a distance. I have a Vortex red dot on the MWS and the obvious choice was the Vortex mini flip to side 3x …except it is £300! So there are others available for £50-100 which is probably the cost of a basic scope but without the hassle of swapping out and re-zeroing. So what alternatives do people recommend? Any brands to avoid like the plague? thanks, Mr Magoo 😂

30-50mm groupings at 25m? My MWS shooting 0.32g BBs makes a ~30mm grouping at 10m and is considered a pretty accurate and consistent RIF. Certainly able to make head&shoulders shots at 45m (verified) and upper body shots further than that if the target has the decency to stand still 😁 I have the red dot pretty much spot on for 15-30m (closer the person is a much bigger target and can use reflexive shooting and further is a bit of a crap shoot with wind / leaves / walking targets! Getting that level of grouping at 25m without it being an air gun with rifled barrel and lead pellets? Yeah....no.
-
I guess it compresses the top part of the magazine (feedlips and gas router end) so you can get the pins in. I usually push the mag against the edge of the work bench with my hip and tap the pins in 🤷🏽

There is a pretty regular core of players at UCAP Gloucester prison. I don’t know of any milsim teams as I have always just rocked up and joined a friendly bunch for the duration of the event. I am in a team but the rest are such slackers we haven’t had a game together since March 😂
-
ASG Ultrair, CrazyJet 250mm barrel, Laylax hop arm and 60deg ML rubber - possibly the MR one? I tested a lot of ammo from a 10m clamped rifle with Warhead & Geoffs 0.32g giving the tightest groupings by a fair margin. The 0.28g are best performers in my M733 AEG, but the MWS just gives them too much spin! I have a Manometer (0-300psi) and some brass fittings saved in my Amazon basket because I have an idea for a airsoft gas pressure tester 🤓
-
Looking good! Nothing wrong with a URG-I 😁 I tried to run my MWS on 0.28g today but even with the hop “off” they were skying at 30m! Purchased a bottle of Vorsk 0.32g (not my first choice but was a small bottle for £10) and with 4 clicks of hop I was hitting peeking heads at 45m+ 😁

HobbyKing UK is re-opening... special offers on backorders
SSPKali replied to RostokMcSpoons's topic in Latest News
Damn it! Their 7.4v skinny packs would have been great for the M733. Now have some LiFe 9.9v that JUST fit in the hand guard with some jiggling and swearing 🤬 -
Been researching different gas pressures for my TM MWS. Usually using ASG Ultrair (beige bottle) and found this handy video comparing different gasses.
“Airsoft Mike” Youtube video shows the following (amongst others):
Nuprol 1.0 - 320fps
ASG Ultrair - 345fps
V6 - 365fps
V8 - 375fps
Nuprol 3.0 - 375fps
Obviously it will vary from platform to platform but a handy guide to, in the words of “Play Your Cards Right”, higher or lower? 😁

Just to chime in, I'm chuffed the graph on the side of the can is being recognised as helpful for working out whats best for you. Just a heads up though, while the Orange & Red are silicone free, the new green does have a small element to it, so for your MWS stick to ultrair for the warmer days.
I posted a bit of a spreadsheet in the MWS thread of my comparison of all 4 of our gasses through my MWS at 23c if you havent seen that. Theres also the price. Ultrair red is available for under a tenner.

AEGs have a set volume of air in the cylinder they will force down the barrel. Gas guns (and I think HPA too. I don’t own one so no first hand experience) will keep pushing out gas to fill the volume behind the BB until it leaves the barrel and the pressure drops allowing the rocket valve to close and divert the pressure to cycle the action. TM gas rifles have 250mm barrels no matter the outer barrel length to limit Joule creep and keep within Japanese laws.
-
Videos are dead on that post ☹️ Got the Steel and Alu bolts set up with G&P stops and regular plastic valves. ~260fps and ~240fps respectively on 0.32g / ASG gas / 25DegC shed 😁 Taking less than half a mm off the back of a plastic valve gives a 20-30fps gain. Rub on some wet&dry on a flat surface….take it slow! G&P adjustable valve (green one) was showing some wear with the grub screw eating a hole in the brass stop - not all the way through but not ideal!
-
Built up a new nozzle tonight to replace the TM one with the broken screw and G&P NPAS that was adjusting its self (and trying to get me banned from the local site Luckily discovered testing at home!) Set up was the same for all gasses. Minimal Joule creep with 0.28 > 0.32g BBs (lighter ones omitted for clarity) 19DegC, 0.32g BBs from a Guns Modify nozzle / valve / valve spring. G&P adjustable valve stopper - three holes for the cross-nozzle screw to go through at different points so it moves the valve forward or back a set amount. MID setting: Nuprol White 265 - 272fps ASG Ultrair (beige bottle) 270 - 276fps So the low power gas is only ~5fps less. As it was close to the limit I changed it to the LOW setting and repeated. ASG Ultrair (beige bottle) 230 - 233fps Nuprol Red 235 - 240fps Bit too low (equivalent to 295fps on a 0.20g) but fine for CQB. So “Nuprol super power gas50000!!!!” only added ~6fps. iT wIlL kiLl Ur GuNz!!! 😂 Might try the mid setting with a cut down valve spring, or just wait for the weather to cool down 😁 According to Vorsk the V6 gas is equivalent to ASG Ultrair, V8 and V12 both higher pressure. Abbey 144a might be a handy one for warmer days when I don’t want to disassemble the nozzle in the safezone. What are others running and do they notice much difference in FPS?

Need help separating upper and lower receivers on TM M4
SSPKali replied to FMairsoft33's topic in Electric Guns
Is it a polymer body? It might be the older type with “rear ears” that the rear body pin goes through. These you only need to remove the rear pin and carefully pivot the upper around the front pin. Search out the TM M733 AEG manual for instructions and pictures.
