SAT Airsoft Taiwan-High Performance Output Valve for Tokyo Marui M870

We 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.

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...

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.

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...

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...

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.

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...
