chas Posted March 4, 2015 Report Share Posted March 4, 2015 Would some be so kind to measure the distance between the two boy pins, the ones located above the rigger guard? I want to buy a side Shell holder for my newly arrived PPS 870 (Tanaka clone) and for now I would wantto go with the saddle made for the Marui M870, as the RS one is a bit expensive for a piece of metal, IMO. http://shop.ehobbyasia.com/angry-gun-cnc-6-shells-carrier-for-marui-m870-shotgun.html#.VPbydbc5Bdg If someone could somehow measure center hole to center hole (since they have different diameters), that would be great.

Zereck Posted March 4, 2015 Report Share Posted March 4, 2015 Taking measures on my breacher it was 51.5mm between the two pins(from center to center of the pins). Quote Link to post Share on other sites

mellvis Posted March 7, 2015 Report Share Posted March 7, 2015 So after more than 1 year in storage, I took out my 870 tactical today and noticed that my gas reservoir bloated to the point where it's difficult to remove from the stock. Damn shame as I only use 134a gas. Any fix for this? Not too keen on buying a new gas tank, unless Marui or someone tweaked the original design. Quote Link to post Share on other sites
renegadecow Posted March 7, 2015 Report Share Posted March 7, 2015 Replace the pins with nuts and bolts. Quote Link to post Share on other sites
Alias1983 Posted March 13, 2015 Report Share Posted March 13, 2015 My m870 shoots only 2 and 5 bbs, outer barrel is wobbly. I get 5 shells on 3 bb mode and the tank is cold enough to make warm jack cold enough to drink the disappointment down. Quote Link to post Share on other sites
Habakure Posted March 14, 2015 Report Share Posted March 14, 2015 Take it back to the shop. Quote Link to post Share on other sites
Alias1983 Posted March 14, 2015 Report Share Posted March 14, 2015 I'm not paying evikes restock fee, I will just upgrade it. So disappointing that this would of left the factory. Quote Link to post Share on other sites
Habakure Posted March 14, 2015 Report Share Posted March 14, 2015 Take some pictures of before and after to see what the fault is and how you fixed it. There's a thread for faults and fixes for the m870. Quote Link to post Share on other sites
Alias1983 Posted March 14, 2015 Report Share Posted March 14, 2015 I'm fairly certain its the transfer bar. So while I'm there I will get an enhanced nozzle. Shouldn't have to do any more for my needs Quote Link to post Share on other sites
Alias1983 Posted April 4, 2015 Report Share Posted April 4, 2015 Well I looked at the nozzle and hops and all is 100%. I used core(local maker of bbs, small of than norm) madbull and elite force. Mb and EF performed slightly better but its not feeding. I will replace the transfer bar but nothing seems odd or worn or broken at all. Worst part is I have people telling me I can't fix it myself. If the bar and lots of lube don't fix it I will trade it for a cam 870 Quote Link to post Share on other sites

Alias1983 Posted April 12, 2015 Report Share Posted April 12, 2015 My m870 does not feed worth a , barrel is loose. I felt taken To the cleaners Quote Link to post Share on other sites
yannourugby Posted April 26, 2015 Report Share Posted April 26, 2015 Thank's for reply @Alias1983 ! I have fix my missfeed issues but now I've got a problem to reassembling the gun, when I'm puting back the hanguard, the pump's arms are catch by a little silver hook and I can't push the handguard/pump to is initial position on the magazine tube. Anyone knows how to fix this thing ? The piece who's catching the arms each time, is the little silver piece, wich is screwed on the body by a black screw, on this photo : I hope you have understood my question, that's diffcult for a frenchie ! Many thanks Quote Link to post Share on other sites
DeltaZero Posted April 27, 2015 Report Share Posted April 27, 2015 Pop over to the M870 owners group on facebook. You might get a quicker response over there! https://www.facebook.com/groups/1503954529842211/?ref=ts&fref=ts Quote Link to post Share on other sites

Alias1983 Posted April 27, 2015 Report Share Posted April 27, 2015 I can't get mine to feed at all so guess it hits the local fs forum. Quote Link to post Share on other sites
Habakure Posted April 27, 2015 Report Share Posted April 27, 2015 Ooooohhhhhh, that's a closed group though. Might not let him in (I highly doubt they'll turn him away, every group I've tried to join has let me in). Quote Link to post Share on other sites
DeltaZero Posted April 27, 2015 Report Share Posted April 27, 2015 They'll let him in i'm sure! 1 Quote Link to post Share on other sites
Alias1983 Posted April 27, 2015 Report Share Posted April 27, 2015 Yeah may take a while for some. What bbs are you all using with your m870 and have it feed. I tried madbull, core and bleh elite force. Core feeds in my gbbr like a dream. So I don't know. Quote Link to post Share on other sites
yannourugby Posted April 29, 2015 Report Share Posted April 29, 2015 It's ok, I'm a TM870 owner's member ! @Alias my BB's are guarder 0.25, it's better but with some shells there is still some missfeed. 1 Quote Link to post Share on other sites
you can`t shoot me Posted May 3, 2015 Report Share Posted May 3, 2015 (edited) My tm m870 and ics m1 garand feed ok with guarder 0.28s most of the time but seem to jam up every so often but G&G 0.28s seem to be better and feed without issue. Saying that I have a tm 870 I bought from pro airsoft supplies which jammed up completely, the pump was stuck half way, sent it back and they replaced part number 870T-36 with a steel replacement and then stated it still wasn`t working so they had to use other parts from broken model to replace other parts which were damaged but since I got it back it never worked, it will not feed right at all no matter what bbs I use. Most of the time with a fully loaded shell it will not rack as the pump jams so I have to eject the shell the rack the pump to clear the bbs and try again until it pumps freely but even then it still only loads bbs half of the time and dryfires the other half randomly. At this point I just gave up on it and am keeping it for parts as I have another m870 and a breacher which I have had no issues with apart from the breacher completely destroying the valve oring on green gas. I did notice that some of the parts seem to be designed slightly different between my m870`s so tm may have changed the design of a few of the parts between batches and some of the parts maybe just don`t work well together or the steel 870t-36 part is slightly thicker than the orginal so it could be that but rather than replacing all these parts with more expensive aftermarket parts and hoping that fixes the problem it would cheaper to just buy a new m870.
