This gun is so much fun :-)
But what is the best plan of attack to improve this?

This is at 9 meters. 9 in a 4,5cm group, and 1 flyer.

Gamed mine effectively for the first time. CQB in a barn with temps around 2c.

Wouldn't cycle at all on propane. Gave a touch of MAP and it ran fine.

Still need more hop but otherwise very near the sweet spot.

Be a dick, fill with duster, chrono, and switch back to propane.

Possibility 1:

Possibility 2:

1. Shim the floating valve forward
2. Trim/Weaken the floating valve spring
3. Make a custom flow restrictor for the nozzle

Duct tape it, Walmart has camouflage for 5$
If both same side up, you need spacer.
If reverse side, then just tape them

Anyone have the Angry Bird 120% recoispring120
Wondering how much stronger it actually is.
With the OEM spring with the bolt on top, I tare the scale and press the bolt down until just before it touches.
Gives me 1250g. Anyone tried that with the Angry Bird?

Greetings from Moscow!
I join you with my MP5A3 (ver. 1)
Thanks to the forum for the solution of many problems. I set the Azimuth bolt sliders and original reinforced nozzle (of VCF). Also i milled original loading ramp (v.1) to make smooth channels in both sides. The gun is no longer jammed balls and then I successfully played 2 CQB games. There was a problem with excessive release of gas, but I'm hope to solve it by changing the size of the inlet of bulb.

Best regards!

What's the temperature when the gas release is excessive?

Normal room, 18-20C. But is not permanent problem. From time to time, and i can't see any regularity.
The feeling that freezes the gas chamber . I think to reduce the rate of filling the chamber and slightly lower power . For CQB it would be even better (now the power 118-121m/s , is on the verge of the permitted) .
