SpankyTheDolphin Posted July 6, 2014 Report Share Posted July 6, 2014 Can someone post up the parts diagram for the 870? I lost mine. Quote Link to post Share on other sites
Norotor Posted July 7, 2014 Report Share Posted July 7, 2014 Wasn't the first batch, I think I bought it around 3 months ago. Quote Link to post Share on other sites
BerserkDS Posted July 7, 2014 Report Share Posted July 7, 2014 The gun immediately stopped feeding. Opened up the gun, and one of the posts on the side of the blade had snapped off. This was an early batch gun. Quote Link to post Share on other sites
DarkLite Posted July 7, 2014 Report Share Posted July 7, 2014 There have been a couple in HK that I know of where the pins on the side of the loading arms have snapped. Quote Link to post Share on other sites
onizuka-gto Posted July 7, 2014 Report Share Posted July 7, 2014 Both Angrygun and G&P version now available on EhobbyAsia: G&P Complete version: https://shop.ehobbyasia.com/g-p-gas-charging-collapsible-stock-seet-for-marui-m870-shotgun.html#.U7oX3PmSy4I Angrygun "barebone" version: https://shop.ehobbyasia.com/angry-gun-retractable-gas-tank-stock-for-marui-m870-shotgun.html#.U7oX4PmSy4I While the angrygun is cheaper, it'll be just the same (more likely more) as you need to purchase a pistol grip and but stock, but even so I'm tempted to get it as i'm hopelessly sill with customisation....

Habakure Posted July 7, 2014 Report Share Posted July 7, 2014 Regarding the loadng arm:- I wonder if it's a weak part or that there is a bit of quality control issue going on? The skeptic in me is tempted to buy a replacement part, just in case. But the superstitious part of me thinks that's playing with fire (buying a replacement is tempting fate). Uh-oh, I've said quality issue about a Tokyo Marui product. That's like firing up the bat signal, but this signal is for fireknife. Quote Link to post Share on other sites
BerserkDS Posted July 8, 2014 Report Share Posted July 8, 2014 I think it's the opposite. Stuff breaks when you don't have emergency parts on stand by. When you're ready for parts to break and have spares, it almost never breaks lol. 1 Quote Link to post Share on other sites

arne71 Posted July 9, 2014 Report Share Posted July 9, 2014 (edited) My Angry Gun stock kit arrived today. Looking very good. But have not had the time to mount it. Edit: Now mounted. Very happy! It`s looking good, and it even works. No leaks yet. Only fired one shell though. Edited July 9, 2014 by arne71 Quote Link to post Share on other sites
Bleedout Posted July 9, 2014 Report Share Posted July 9, 2014 Mine arrived the other day. How was yours to fit?. Mine took a little bit fiddeling to get it too seal fully. This going to mean everyones back to running these on propane?. Quote Link to post Share on other sites
arne71 Posted July 9, 2014 Report Share Posted July 9, 2014 (edited) Yeah, you really need to turn the stock screw quite hard to make it seal properly. Was not much of a problem. More kind of annoying that I did not get it right the first time. Now I`ll just have to fit the rail as well. Edited July 9, 2014 by arne71 Quote Link to post Share on other sites
Bleedout Posted July 9, 2014 Report Share Posted July 9, 2014 Least I know it wasnt just me. Was paranoid about cross threading something so 1st time it didnt seal just right. Qiite impressed at how much length it takes off the gun though Quote Link to post Share on other sites
mrsevenstars Posted July 9, 2014 Report Share Posted July 9, 2014 I also have one and have a slight leak that developed after a full days use. Bleedout, what type of fiddling have you done? My gun currently has a leak that soundslike the gas is running through the body and sometimes stops after being fired and then starts again a couple shots later.

GSO-Geko Posted July 10, 2014 Report Share Posted July 10, 2014 I also have one and have a slight leak that developed after a full days use. Bleedout, what type of fiddling have you done? My gun currently has a leak that soundslike the gas is running through the body and sometimes stops after being fired and then starts again a couple shots later. Probably the internal gas chamber leaking due to poorly lubricated valve orings. You'll have to take that bad boy apart. Quote Link to post Share on other sites
johnyew Posted July 10, 2014 Report Share Posted July 10, 2014 My 870 must be cursed as it has not worked properly since I bought it. Anyway, Replaced the nozzle yesterday as the top nozzle broke on the original one. Put back everything together and it worked beautifully for about half a dozen shots in 3-shot mode. Cycles smoothly and loads/chambers perfectly for those half dozen shots. Should have stayed there in 3-shot mode. Switched to 6-shot mode and everything goes downhill from there. FML!!! First rack and it gets stuck, misfeeds and unable to shoot. Took the shell out(all using Marui shells), it racks, BBs fall out, able to shoot. Reinsert Marui shell, try to rack it again but fails halfway. Strong armed it through and it fires. Strong arm it again and it shoots. Switched it back to 3-shot mode and everything goes to hell. Unable to rack it smoothly. Took it apart several times to check but cant find teh root cause. So today, went to Ehobby and got the CNC loading plate as a final resort in fixing this gun but only replacing it tomorrow morning to let my nerves settle down a bit. if this does not fix it, i'm going to sell this as a parts gun and get a new gun when Ehobby has their Xmas sale. Wish me luck. Quote Link to post Share on other sites

My gun currently has a leak that soundslike the gas is running through the body and sometimes stops after being fired and then starts again a couple shots later.Mine did that. As suggested quick spray of silicone oil on ALL o-rings. Also check your oring from the gas nozzle isemt in your old stock as its needed. To get mine to seal right infound I needed to standt the gun end-on and apply a bit pressure to the "top" of the adapter ( where it meets the top of the reciever) until the screw was fully tightened.

mrsevenstars Posted July 10, 2014 Report Share Posted July 10, 2014 Gso Geko Ive assembled it and fixed the leak at the joint where the main core section interfaced with the stock but now i have an intermittent firig issue. It will fire inconsistent amount of shots per pump or non at all, all the way through the shell. I had used this shell before and not had an issue with it but after the reaassembly it has developed this problem. Any ideas to what i had missed? Quote Link to post Share on other sites
mrsevenstars Posted July 10, 2014 Report Share Posted July 10, 2014 @bleedout thanks i was able to stop it from leaking... for now. Lol Quote Link to post Share on other sites
Bleedout Posted July 10, 2014 Report Share Posted July 10, 2014 Mine leaked at first and after tje above its been sitting 3days will a 5-6 second fill in it and seems fine. (I only Putva little in to force any leftover oil into the oring seals) Quote Link to post Share on other sites
Habakure Posted July 10, 2014 Report Share Posted July 10, 2014 Fingers crossed, I've had no issues with the G&P version (stock adaptor). It was easy to install and so far (touch wood) it has held it's gas and shoots the same as the original Tokyo Marui gas in mag system. I've even put the old stock back on to check it still worked and it did (it also let out a bit of gas on the first few shots). I hope that the problems the above users are having is an isolated incident (as angry gun products are generally good to go). Quote Link to post Share on other sites
Bleedout Posted July 10, 2014 Report Share Posted July 10, 2014 Think its just the fitting. Video makes it look easy but guys prob test fitted 100s so has the "knack ". Quote Link to post Share on other sites
Habakure Posted July 10, 2014 Report Share Posted July 10, 2014 Hopefully so (80% so), but it does make me happy that I went with the G&P as that was easy to install (even came with a o-ring). Though it would have been nice if the G&P version came in a box instead of their plastic bag packagings. Quote Link to post Share on other sites

Probably this You'll notice the selector spring is on a little nub. If the spring is not in this position, you will get inconsistent feeding. Quote Link to post Share on other sites
Bleedout Posted July 10, 2014 Report Share Posted July 10, 2014 True. Though I think g&p made a mistake in only selling there kit with a pistol grip and stock when most people will replace them anyway with what they want. Quote Link to post Share on other sites
Habakure Posted July 10, 2014 Report Share Posted July 10, 2014 (edited) If people are buying the angry gun just because of cost, then fair enough. If you don't like the stock and pistol grip, that comes with the G&P, again, fair enough. But a lot of products are released with parts that people change (grips, stocks and ris units etc), so it didn't put me off (and I like the grip, just not the stock tbh). I'd always said, if one of these had better gas efficiency, then I'd buy that one. But initial tests have shown that both hold about the same, or slightly less, as Marui's gas in mag system (even though people summer used that the angry gun should have more space for gas). So for me it comes down to looks. I prefer the higher stock tube position of the G&P model. Edited July 10, 2014 by Habakure Quote Link to post Share on other sites
