PureSilver Posted November 21, 2014 Report Share Posted November 21, 2014 Interesting. What sort of FPS are you getting? Does the valve leak when you use propane? Quote Link to post Share on other sites
danr Posted November 21, 2014 Report Share Posted November 21, 2014 Sadly the chrono just died. Hopefully should have access to a different one tomorrow. No leaks thus far on propane Quote Link to post Share on other sites
PureSilver Posted November 21, 2014 Report Share Posted November 21, 2014 Did the OEM valve leak when you used propane? Quote Link to post Share on other sites
danr Posted November 22, 2014 Report Share Posted November 22, 2014 I'm not sure where it was, but I developed a leak somewhere in the body of the gun before I changed the valve. I was able to stop it with a bit of silicone in the gas chamber. Quote Link to post Share on other sites
Trap Posted November 23, 2014 Report Share Posted November 23, 2014 Would be interesting to see what power gains you get from different types of gas. Quote Link to post Share on other sites
danr Posted December 2, 2014 Report Share Posted December 2, 2014 With the SAT valve and the SAT tightbore barrels, I chronoed at 355 with .25g BBs 2 Quote Link to post Share on other sites
PureSilver Posted December 2, 2014 Report Share Posted December 2, 2014 Thanks! So with the valve but without the barrels, sub-350fps should be achievable, which sounds CQB-ready to me... Quote Link to post Share on other sites
danr Posted December 2, 2014 Report Share Posted December 2, 2014 I was tempted to try the barrels alone and the valve alone but once I started taking apart I decided that I wasn't enthusiastic enough to deal with the complicated disassembly more Quote Link to post Share on other sites
Ryaw Posted December 10, 2014 Report Share Posted December 10, 2014 Everybody here is probably already aware, but there is a private Facebook group for M870 owners and it's a goldmine of knowledge - https://www.facebook.com/groups/1503954529842211/ Hopefully I've not broken any rules by posting this. I'm just trying to help other M870 owners out. Quote Link to post Share on other sites

Sir Stephen Posted December 13, 2014 Report Share Posted December 13, 2014 (edited) my shotgun has suddenly stopped cocking (completely jammed, maybe 1mm of flex form the pump), and when i try to take it apart the trigger section cant come out (also jammed on something) so i cant even get the gun apart. anybody had this issue? ***UPDATE*** the lefty hand side cocking handle arm (if that's what its even called) appears to have uncouple from the silver piece inside the receiver (how i have no idea) but its back in the correct position and racks' beautifully again.

CapnNukem Posted December 21, 2014 Report Share Posted December 21, 2014 Anyone had any experience in the cleanliness of the barrels causing 6-shot not to function? Quote Link to post Share on other sites
Trap Posted December 22, 2014 Report Share Posted December 22, 2014 My barrels looked like Marui had used them as a toilet from factory but it didn't stop my 6 shot mode from functioning. Quote Link to post Share on other sites
CapnNukem Posted December 22, 2014 Report Share Posted December 22, 2014 Thanks, appears Airsoft World is trying to pull a fast one. Second 870 tactical they've sent to me with the 6 shot not functioning and after telling me only certain brands of BB work properly (and nothing heavier than 0.2g) they are now saying its because the barrels were dirty..... I smell BS and a Paypal claim coming up... Quote Link to post Share on other sites
arne71 Posted December 23, 2014 Report Share Posted December 23, 2014 Sounds like bs. Read through this topic. I think the 6 shot issue is pretty well covered. Quote Link to post Share on other sites
Trap Posted December 24, 2014 Report Share Posted December 24, 2014 There's a wealth of knowledge about problems with 6 shot and what causes them available in the TM M870 Owners Group over on facebook. Mine has shot 5 or 6 shots depending on how it feels since purchase. Quote Link to post Share on other sites
CapnNukem Posted December 25, 2014 Report Share Posted December 25, 2014 Thanks for your help guys, I thought this was the case. After much arguing - them saying it was my fault because the barrels were dirty, the wrong brand and weight of BBs were used, and even the type of gas used was mentioned at one point.... I directed them to this thread (and 3 others along the same lines) & reminded them of their own sales policy and managed to get a refund of the gun minus a "restocking fee" (load of *suitcase*). They still maintain it was my fault for not cleaning the barrels on delivery of both M870s and that I'm the only person they've encountered that's had issues with the 6-shot not working. Seems pretty common to me but what do I know? My short time with the gun I was impressed by the externals, but I guess I expected more reliability from Marui, in the end it was a choice between no gun or a £290 tri-shot - I chose no gun and the money in my pocket for other things. I was itching to HPA it as well.... Quote Link to post Share on other sites
Trap Posted December 25, 2014 Report Share Posted December 25, 2014 In 16 years of Airsofting Iv never had a TM gun that has worked as it should from purchase, I still keep buying them tho :s Iv only skirmished my m870 once and absolutely loved it. Have done a lot to it since and can't wait to get back out with it again. It's a shame they are coming out of the factory the way they are really. Quote Link to post Share on other sites
CapnNukem Posted December 26, 2014 Report Share Posted December 26, 2014 I've had luck with a few of their AEGs when that's all you could buy from Airsoft Dynamics, Rebel Troop etc, but I've recently had a few bits and pieces from TM that have left me underwhelmed. I'll stick with the Chinese clones from now on I think. I had a go with another players 870 Breacher and loved the 6 shot (which performed flawlessly) on a whole they seem more reliable than the Tacticals going purely on internet reading. Maybe they ironed out some bugs in the internals of the Breachers, perhaps different spring strengths, slight reinforcement to certain parts? If they sold it as a trishot with £60-70 off the price then I would have kept it, the quality of the externals is a definite step up from the usual all plastic of the tri-shots, although the barrel had the slightest bit of movement on mine.

Trap Posted December 26, 2014 Report Share Posted December 26, 2014 That barrel movement has developed into quite a lot on mine. Mine is a cut down tactical. I guess Iv got quite lucky with mine tho in comparison to how others have turned up. Ah them were the days, my first AEG was a First Factory HK51 from airsoft dynamics. I had a fair few oddities from them, hunted out when one of them was over in Japan. Quote Link to post Share on other sites

PureSilver Posted December 30, 2014 Report Share Posted December 30, 2014 Isn't that exactly the same as the Angry Gun one, except that they've actually engraved 'Mesa Tactical' on it? 1 Quote Link to post Share on other sites
DeltaZero Posted December 30, 2014 Report Share Posted December 30, 2014 (edited) My thoughts too.. Infact didn't the angry gun ones eventually have "Mesa Tactical" on them too? Edited December 30, 2014 by DeltaZero Quote Link to post Share on other sites
BerserkDS Posted December 30, 2014 Report Share Posted December 30, 2014 It's a copy of it. The angry gun has two versions. One with trademarks, and one without. The nebula one looks like it made of some lightweight cheap aluminum. Possibly recycled coke cans. Quote Link to post Share on other sites
