    THE TM MWS thread

    uhm what key size do I need to open the magazine ? for the green gas mod. My keys are too big and I need to get a new one, smaller Also, for noobs like me, this looks pretty helpful (looks like a thorough assembly/disassembly tutorials for the mws): Later edit: Did the green gas mod and I learned two things: -it's much easier to use a guide (used a log screw driver) to reinsert the magazine spring, just insert the screw driver through the spring until it reaches the spring tube and then just push it along -even with using a pipe cutter, there can be aluminium shavings left that may reach the o-rings and cause a bad seal. Happened on one the the mags, tested it after and it was leaking and the cause was this, very small shavings (1mm or so) around the o-ring. Cleaned them up under a magnifier and problem solved Also, the prometheus barrel that I got ( reference: https://www.fire-support.co.uk/product/prometheus-603mm-eg-inner-barrel-for-m4a1-mws-370mm) fits perfectly, the hop up cut out and all the grooves are identical with the stock marui and length wise it ends exactly where the outer barrel ends, without the flash suppressor.

    Wait, won't increasing the BB weight drop the fps ? Or this is where the "infamous" joule creep ... creeps in ? Later edit : never mind, I thought you said 390 FPS with the heavy BBs but I assume it's 390 with .2s Also, to understand your previous post: Ideal shot = Ideal FPS+Ideally weighted BB @ Ideal hop spin and from here onward, increasing the FPS will make the BB travel faster but becoming unstable because it doesn't receive enough hop spin for that speed but then, if compensating with more hop spin, the BB will shoot to the moon as you said, because it's too light, hence a heavier BB is required but then the default TM bucking/nub are too soft to actually apply the hop spin and then we need a tougher rubber/sturdier nub .... that's the gist of it, right ?

    that makes a lot of sense actually, I never thought of the relation between fps/hopup/bb weight... TNX. And this is extended by hop-up style/rubber hardness and so on ... Anyway, I already ordered the barrel and an RA npas, the shop had only 2 left so I was like ... why not And for limits, I think I have 400 fps available to me so for now I will probably stay with the longer barrel and the 25s or 28s, get a feel for the gun, how it shoots/hops and so on. Also, I need to stop buying stuff for a while, otherwise my significant other will probably start using the guns .... on me

    Let's see if I get this right. Using .28s let's say, even with the longer barrel, I will see an increase in FPS but not in range/accuracy, because the BBs are too light and will just fall anyway at the same-ish distance ?

    K, so FINALLY my MWS is en route, should arrive tomorrow. Already I am thinking of upgrades and the 1st thing that I want to change is the barrel, it just itches my brain to have 12 cm of nothingness in the outer barrel, so I will go for a Prometheus/Laylax 370 cm 6.03 stainless steel beauty and I would like to kindly ask what changes can I expect ... I am planning to use .25/.28 BBs max, so probably will not change the hopup system. I assume the obvious effect will be an increase in FPS (wo1f was sayin smth about 35-40 for a 6.03 250 mm barrel ?) . How about accuracy, joule creep ? How about gas consumption ? will it go up/down ?other unforeseen consequences ? ... tnx

    Tnx for the answers ... so yeah, either stinky MAPP or those "magic" tabs then. Probably going to try the tabs. Meanwhile, my TM M9A1 arrived, pretty pretty pistol Random tip: I got and IMI defense polymer holster for it and it didn't quite fit. It would go in, but forcefully so I fixed it by putting the holster in the oven at 60 C, leaving it a good while and then sliding the gun repeatedly in/out and finishing with putting the holster with the gun in it, in the fridge, for the thing to cool down and retain the new shape. Works perfectly now

    found this crazy crazy product: https://www.amazon.de/Warmpack-Zehenwärmer-Wärmepads-Temperaturen-Fußwärmer/dp/B00P10GDRS/ref=pd_bxgy_200_img_2?_encoding=UTF8&pd_rd_i=B00P10GDRS&pd_rd_r=57e4dd0e-ca49-11e8-ad7e-013f963e194b&pd_rd_w=yGQd5&pd_rd_wg=CSqN3&pf_rd_i=desktop-dp-sims&pf_rd_m=A3JWKAKR8XB7XF&pf_rd_p=c16bc8ff-3133-444d-b32d-3575d0da89ee&pf_rd_r=83M4MMA2F3Q29VNRZQB0&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&psc=1&refRID=83M4MMA2F3Q29VNRZQB0 if these work, than it's just about sticking them on the mags, one to each side and should be good will definitely test them. Probably will be laughed at but whatever

    Ok, I found something extremely interesting: the video is in German but using google generated English subs does a pretty good job. In short, the guy fills up a gas pistol magazine, with green gas and then injects only a small amount of CO2, using that charger, maybe half a second to a second. Thing is, the result is very very nice and some people on the German Amazon review page for this product were reporting also good performance in cold weather. Any thoughts on this ? Sounds like a miracle cure for my cold weather anxieties

    found this pressure chart for MAPP: and comparing this with the Nuprol chart above, it would seem that MAPP is a bit more powerful than Nuprol 3.0 but less powerful than Nuprol 4.0 at 10 C degrees: MAPP 113 psia (psia is psi absolute, which means 124.7 psi at see level because +14.7 atmospheric pressure) Nuprol 3 111 (if it's psi or 125.7 if those figures are in psia) Nuprol 4 136 (if it's psi or 150.7 if those figures are in psia) Any thoughts on this ?

    incredibly, I can buy MAPP gas from amazon in Germany ... 13 euros for 750 ml can good to know. Meanwhile, flecktarn in the bathroom (still waiting for the guns... )

    I have a question, what is a decent low temperature to use a TM, with the green gas mod, and be able to shoot one full mag of BBs properly, in semi auto mode ? Let's say with green gas/propane (I bought ProTech green gas, any experience with it ? Is it propane lvl or below/above ? ). Would 0-5 degrees (Celsius) be ok ? With let's say mags kept on the chest side of a plate carrier, so hopefully "stealing" some body heat. And I have a crazy idea that pokes at my brain for a while. Does anybody know if somebody tried a CO2 mod for the TM ? Couldn't find anything with google search ... but I was thinking, how about taking a WE/GHK/others CO2 M4 mag, that has the same or a very close shaped outer shell with the TM one and maybe 3D print the inner top part (nylon or similarly strong plastic), so it still fits the original mag systems/shell but now has the upper part of the TM (gas outtake and BB loader lip). It would be necessary to check somehow the output of the valve on a trigger pull to see if it doesn't release too much pressure for the TM to handle and maybe replace it with a valve that has a lower output, if such a valve even exists but ... yeah, what do you guys think about this idea ? P.S.: still waiting for the gun to arrive, hopefully next week.... Later edit: I found this chart for nuprol: Comparing Nuprol 2.0 with this chart https://www.engineeringtoolbox.com/propane-butane-mix-d_1043.html it seems that it behaves like pure propane.

    yup, got this one 1,5 kilos ... pfff, also flecktarn because, when in Rome...

    Well, I went ahead and bought the stuff, gear and MWS (no sidearm for now) and besides getting over the dizziness of paying that much in one day ... I did a weight estimation, and it seems my beloved gear will weigh about 14.5 kilos (that's about 32 pounds) and if I get the pistol and mags, holster and what not, a red dot and a flashlight I will be at 17 kilos (~37.5 pounds) so .... HOLY SHIT
