Picure Posted July 12, 2014 Report Share Posted July 12, 2014 SAT Airsoft Taiwan-High Performance Output Valve for Tokyo Marui M870We have completely redesigned the output valve of the Tokyo Marui M870 to withstand heavier gasses like green gas and red gas. Our product also greatly improves gas efficiency as it eliminates all valve leakage problems. This upgrade will also increase muzzle velocity significantly.

arne71 Posted July 12, 2014 Report Share Posted July 12, 2014 Would the shotgun still work with normal 134 gas if you install this valve? Link to post Share on other sites
harborne blue Posted July 12, 2014 Report Share Posted July 12, 2014 Am I the only one who can't see the point of a shotgun that shoots 400+ fps? It's no good for CQB and in woodland, your going to get 3-6 BBs winging off in all directions, with (if your in the UK) a minimum engagement distance of 20m. Sniper shotgun? Whaaat? Also can't the new Angry Gun and G&P stocks take green anyway... Link to post Share on other sites
Horsem4n Posted July 12, 2014 Report Share Posted July 12, 2014 well, it could be very useful outside with heavier BBs in the US at least. i imagine that you can still load it up with duster for CQB. but then again, im not sure id trust the chrono readings. it seems consistent, but chronoing multiple bbs at once is very rarely accurate.

blobface Posted July 13, 2014 Report Share Posted July 13, 2014 I did experience the occasional leak from the gun when using green gas, not from the gas tank (or AG stock) nor the connection between whatever gas reservoir to the body, but the leak is from the output valve, essentially coming out of the outer barrels, it's very audible, but usually goes away once after I fire a shot, so I assume that's what they set out to address, I agree that it's a bit pointless to make it more powerful, I can appreciate a kit that will fix the leak when using green gas, but not the extra power...

Picure Posted July 15, 2014 Author Report Share Posted July 15, 2014 Would the shotgun still work with normal 134 gas if you install this valve? Yes, it will still work with HFC134a or Duster. I recommend you use HFC134a or Duster for CQB and Green Gas for woodland/outdoor games. Link to post Share on other sites
GlockworkOrange Posted July 15, 2014 Report Share Posted July 15, 2014 Doesn't interest me, but it's always good to see new parts for the 870. I'm really exited about the Laylax wood kit coming out soon! Link to post Share on other sites
PureSilver Posted July 21, 2014 Report Share Posted July 21, 2014 I agree that it's a bit pointless to make it more powerful, I can appreciate a kit that will fix the leak when using green gas, but not the extra power... My thoughts exactly. For me the ideal situation would be a valve that doesn't leak with propane and maybe bumps the power just a little closer to 350fps. Running at 400fps is impressive but quite useless in the UK, especially with non-adjustable hop-ups... Link to post Share on other sites
Wingmann Posted July 22, 2014 Report Share Posted July 22, 2014 I agree fully with blobface and PureSilver. Mine does as blob's does, BTW. I haven't tried with 134a but I guess it'll hold normally. Link to post Share on other sites
mrsevenstars Posted July 22, 2014 Report Share Posted July 22, 2014 Well i for one being in the US would welcome the capability to run green gas even if it comes with a slight power spike. Mine does as others do and leaks gas out of the front of the gun. It seems to hold on 134a (duster) but i have yet to use it on 134a exclusively to see if it will leak again. I cant wait to try the SAT valve. Link to post Share on other sites
onizuka-gto Posted September 3, 2014 Report Share Posted September 3, 2014 I do like the idea of doing close to 400fps on 6-shot mode. Any idea of when this will come out and how much? Link to post Share on other sites
GSO-Geko Posted September 26, 2014 Report Share Posted September 26, 2014 BACK FROM THE DEAD! Anyone have any news on this? I'd love to combine this with my HPA setup. Link to post Share on other sites
onizuka-gto Posted September 26, 2014 Report Share Posted September 26, 2014 Funny enough I contacted the Taiwanese shop, they told me they will be sending stock to redwolf airsoft Hong Kong. Around end of September they said, if that's true then it should be ready around Octoberish. They didn't give a price though. Link to post Share on other sites

bradnuts Posted October 14, 2014 Report Share Posted October 14, 2014 It's available! But according to redwolf's description, it is not compatible with the angry gun stock? That is kind of a bummer. Not sure if I should purchase it now...http://www.redwolfairsoft.com/redwolf/airsoft/Accessories_GBB_Valves_Kits_SAT_High_Performance_Output_Valve_for_Tokyo_Marui_M870_Original_Stock_Series.htm Link to post Share on other sites
onizuka-gto Posted October 14, 2014 Report Share Posted October 14, 2014 But that means i can install it into my breacher and make it outdoor viable as well as indoors. Link to post Share on other sites
