Tokyo Marui M870 Tactical Gas Tri-shot Shotgun- picture, text and video review

Recommended Posts

I might have to wait a few batches before I pick one up in Canada atleast, knowingly it'll be probably 400+tax(1.13) here, haha.

 

Would like to hear all the problems and solutions before getting into one.

 

Thanks for the detail feedback(s).

Good news, Tokyo-model took back my shotgun for inspection, so I'll just see what the verdict is.

Either they fix it, or I get a new one or maybe they are just going to give it back to me? Who knows!

I'll keep you all updated one they get back to me.

 

Also a good idea to wait a little later, while it seems like it can run on green gas, (even the redwolf youtube presenter was using it) both ehobbyasia and redwolf both caution about using it.

As it's originally built for 134a gas for the Japan market.

But from personal experience, the magazine is clearly feels and looks like it can handle green gas, whether that means it will lower the lifespan of your breacher (wear on internals) is yet to be seen.

So running on green gas is at your own risk.

Well I never had any feeding issues with mine but the gas tank was indeed *suitcasey*. I replaced the two pins with screws and they did hold the sides of the tank together, however the upper and lower part started leaking too later, so now Im thinking to use some kind of sealant. My breacher is in customs, here is hoping that tank is better on this one.

Your don't see any ballooning of the gas tank of the breacher, it's very solidly built, feels like a gas blow back glock magazine.

But it is a fact that my internals jammed after 70 shots while running on green gas.

So whether this is because of faulty internals or because I was using green gas, I'm not sure.

I did a shot count on an angry gun stock adapter today with green gas. I was about to get 120 shots out of it. Though you do hear a noticeable drop after 80 shots.

 

G&P stock, shot count is never consistent. I am going to attempt a disassembly of it. maybe it needs oiling, but my shot count always fluctuated since the day I got it.

That was 120 shots in a row, no break in between.

That's pretty awesome. Mine is working nicely, but I haven't done any tests.

Woah, that's steep.

Oh, I wouldn't recommend .25 in breacher, the grouping is tight up to 10m, heavier than .23 bb you ain't going to get much range, not to mention the spread is less in 3bb mode.

Pumped out a few shots out of my 870...feeds 3 rounds and 6 rounds on the selected setting.

 

That tank though...puffed up even with 134a....shouldnt have stored it for 4-5 months loaded. Lol. Oh well...its not leaking. Maybe ill just make a pull tab for it....or just get a new tank. Whatta drag...

So I replaced the sealing rubber on the bottom of the gas tank with a thicker one. I had to hammer the bottom back in because it was a bit too thick but with this and two screws holding the sides together the tank now holds gas fine.

Finally ordered the new loading arms.. hopefully they wont take long to arrive so I can get this back in the game. Ordered the Nebula reinforced plastic nozzle too. Anyone had any experience with it?

I got my breacher back from the shop, apparently some bb jammed inside, they didn't have to replace anything though.

They recommend higher quality bbs....

So that's that, problem was not related to the green gas and whether the jamming is a mechanical or bb quality problem, only time will tell.

 

So here is a finished version of my breacher

will be making a breacher belt waist holster for it, shamelessly copying the bladetech version (love how it holster the shotgun).

I'm only using kwa/KSC .25g bbs in my shotty as I've never had any feed issues with them in any gun

 

Depending on which bb I use, mags jam....even with bioval .25g bbs, my kwa m11 magazines jammed...same with my kwa mp9 mags.

 

If a specific brand/weight bbs need to be used for these things....so be it. It's a small price to pay so it operates well.

 

Supposedly my breacher is in Chicago....same with my m&p. Hopefully the party receiving and shipping my items out get it out soon. Last update for the m&p said that final delivery was made yesterday. If they shipped it overnight yesterday....it'd be in my doorstep today. Who knows....I'm at work anyway so I can't play with it. Lol

Oh I was thinking of getting the upper rail with side saddle, but that thing is about hk$550, milled aluminum.

I do like that stock though, Magpul is it?

Good luck on the holster; hopefully some Chinese company makes a replica since they are pretty hard to come by.  And maybe a replacement forend with the cutouts for a light.

Having read through this whole thread, hearing a lot about jamming and parts breaking, does anyone have a definite opinion either way on the full sized 870 and its overall quality?

 

Cheers
