Me too! but thanks for the concern. Right now, i've decided to take a break, still can't get to my original goal of getting to that forearm.A very tricky issue has come up. My G&P replacement will have to wait until tomorrow. If my theory is correct, seems like i need to get a new tool to get down that long barrel... Anyway, i hope i get it done tomorrow! i documented everything so far, but it seems like im still missing a spring...or something that suspiciously looks like it should have a spring in it. But i can't for the life of me find it, remember seeing it or see it in any of -
hmmm.....60% there! But how do i get the outer barrel and the forearm off? So troublesome.....

THe mag-extension is very easy, you just screw off the original cap at the end of your magazine tube and just screw on the bit. simple. but yeah, my experience with taking apart my maruzen and the ACM 500 is that you have to take the stock off then take out the internal, to get arms of the foregrip to come off, before you can even think about getting it off the magazine tube. For reference, im looking at dismantling guides of the original spring powered TM shotguns, as this is what the m870 is based upon. I'll get back to you if i feel confidence enough to start and get docume

Yeah, I need a take down guide, haven't fitted my g&p forearm yet. Still don't sure how to take it down.

Goddammit g&p! STOP TAKING MY MONEEEYYY. *goes down to get forearm A*

Me too blob face! Would love to have yours. Oh well, if it makes your feel any better, when i get one i'll post pictures here of how expensive and horrible it is. bask in the glory of how it ruins my shotty...eh?

there there.....

Dammit! I was in Tokyo model shop just yesterday could of got that.... Gah. I'll have a look again this Wednesday, I really been looking for a side saddle and something to stop my buttpad from falling off..

Got the front mount and the dytac extension tube. For everyone wondering why the laylax version is so effying expensive (HKD$360~) compared to the dytac (HKD$138~) its all down to the material. Laylax is made from thicker milled metal, while the dytac is from rolled metal. Personally i don't intended to use my m870 in any outdoor games so the dytac was fine for me. But if you intended to throw your shotty about and use it on skirmishes outdoors, perhaps the laylax version is better.

Fantastic! Best news to hear on pay day! I'll go drop by TMC retail shop after work. Thanks mate!

Which Hong Kong retailer?! I need this!!

I profess i have never dismantled any fill-valve and can only conclude from the observation i have seen so far. If however that method you describe is possible, i'll give it a go. Unfortunately, i didn't know that it'll take 30 seconds to fill the m870 gas magazine, i'm curious where did you hear this from? The m870 manual states no time and only list that when the gas fountains from the fill-valve, is a sign that the magazine is empty. On other gas magazines, i've learnt to fill up a little, wait until the gas has settled then fill up again. However this only applies to my o

Just an update from last Saturday skirmish with the m870 in ambient temperature of 28 degrees Celsius with green gas (WE brand). I have to say I was very disappointed, the gas mags were kept out of direct sunlight and were an average surface temp. Of 23~24c, first game the green gas filled the tanks for about 5 seconds before venting. With this amount . Got about 10 shots off, by the 3rd time I had to refill, the gas vented immediately from the inlet a sign that the valve has closed. After this . Could only get 3 or maybe 5 shots off. Seems like the gas immediately expanded inside and close

Cheers wingman! It's safe (well, not safe?) to say the minute . step out my flat, it'll be over 25C already! Ha!

NICE! Finally we can see inside! Thanks Zereck! I can see what you mean, the silicone rubber gasket is located on the inlet of the shell, in theory this should allow excess gas to leak if the container expands due to the pressure. But actually it might not, i can understand now why they mentioned not to use this magazine above 40 degrees C. Now this is only my personal theory, but the reason they put the gasket on the inlet, is because they are relying on the principle of cold welding between the gas reservoir lid and the shell to create a tight gas-proof joint. (The principle o

Unfortunately yes, that's because the aluminium will slag before the pot metal/steel and become unrecoverable to join unless you have the right flux. Of course if you do go ahead with just the normal flame and flux you can still "hold" them together, but it'll be a temporary one when both materials aren't bonded to the solder. Because all the strength will be carried by your solder and eventually when get a bang or drop it hard or/and by the constant racking and firing, it'll crack cleanly.
-
Easy answer? Yes. Long Answer? No. You can "braze" them together, but considering the quality of the material, the temperature and added use of additional specific flux to get aluminium and steel to work together so that it'll bond to your solder? Don't bother. just go with the JB Weld, it'll save you a lot of headaches.
-
Well, i was gonna say JB weld, as any blowtorching might ruin the finishing, but i dunno what colour the chemical epoxy of JB is like. I think whatever is easier for a spray paint to hold on, cos nothing worse then seeing an off colour weld on your baby when you out skirmishing

What a waste.....at least you could of taken it apart so that we can have a look inside.....

aluminium tubing, internally tapped so it can be screwed on?

I have to say, there is considerable dispute into how many shots the current tanks can give, my own experience with imne, has been over 30 shots on one full tank so far. Granted i'm not so sure personally how many i can get from my tank under green gas as i stopped after that (ran out of time). However you can see for yourself how many shots it is capable of, just watch the video below by KhanSeb: http://youtu.be/dwA1oIdLXMM?t=10m20s He managed to get 100+ shots in 3 round burst and 60+ shots in 6 Round burst.

Gas cannister are a circular shape for a reason, it can have thinner walls because it's stronger structurally. The TM tank on the other hand is a elongated oblong, naturally it'll be weaker than a circular shape, but on the other it is equally very easy to rectify reinforce with simply thicker walls. You only have to see a Maruzen pistol grip tank, a short oblong shape, but the thickness of the metal is clearly as tough as what you would find on a TM glock magazine. I don't think the problem is entirely a metallurgical issue, after inspecting it closely i see some merit in Baddbaz comment

Well, i learnt something new everyday. Thanks for the info! I'm not sure you can compare a general pattern gas cannister with design specification to comply with international transportation law and usage with the issue at hand, especially when you are comparing this to a gas tank that was designed for essentially a recreational replicate toy gun. But i agree, the previous models of Tokyo Marui gas products have been quite accommodating to the use of green gas, despite the obvious home market focus that Tokyo Marui modus operandi. I have to wonder if it's due to factory productio

You are certainly right, however it's not coincidence that Japan uses it's own standards, from paper size all the way down to gas tanks. By their standards, these tanks are within safety margins to HFC134a gas usage. But it's no coincidence that in the rest of Asia the commonly used engineering standards are BSI or DIN which are up to international scrutiny and are typically over specified (Something about British and German mentality that things are going to be abused so might as well factor it in!) No one uses JIS in this region outside of Japan, in fact not even the Japanese compan
